WEBVTT - Curing Concrete

0:00:00.360 --> 0:00:04.920
<v Speaker 1>Curing concrete. Concrete makes up half of all man made

0:00:04.960 --> 0:00:08.239
<v Speaker 1>stuff on our planet, and its use will double in

0:00:08.320 --> 0:00:11.080
<v Speaker 1>part to battle climate threats created by the production of

0:00:11.200 --> 0:00:16.080
<v Speaker 1>concrete itself. Industry can deliver cleaner versions, but how soon

0:00:16.800 --> 0:00:19.840
<v Speaker 1>the answer might lie? With four Indonesians from a tiny

0:00:20.040 --> 0:00:25.720
<v Speaker 1>disappearing island by Ted C. Fishman read aloud by Markleidorf,

0:00:27.000 --> 0:00:30.120
<v Speaker 1>People just don't realize we're still in the Stone Age,

0:00:30.560 --> 0:00:33.880
<v Speaker 1>or that humans will always live in the Stone Age.

0:00:34.560 --> 0:00:39.600
<v Speaker 1>Donald mccoolidge, retired senior paleontologist, University of Illinois at Urbana

0:00:39.720 --> 0:00:43.720
<v Speaker 1>Champaign I first learned about the legal challenge that would

0:00:43.760 --> 0:00:47.720
<v Speaker 1>become as Mania at All versus Wholesome in twenty twenty two.

0:00:47.960 --> 0:00:51.560
<v Speaker 1>I'd been reporting on Wholesome Limited at the company's headquarters

0:00:51.560 --> 0:00:56.000
<v Speaker 1>in Zoog, Switzerland. Wholesome, one of the world's biggest cement makers,

0:00:56.400 --> 0:00:59.040
<v Speaker 1>is both an industry innovator and a major emitter of

0:00:59.080 --> 0:01:03.520
<v Speaker 1>atmospheric carbon dioxide, the gas responsible for roughly two thirds

0:01:03.520 --> 0:01:07.560
<v Speaker 1>of human caused climate change. It had been facing aggressive

0:01:07.560 --> 0:01:12.720
<v Speaker 1>confrontations with climate activists. Protesters had occupied a quarry, blocked

0:01:12.760 --> 0:01:18.320
<v Speaker 1>company trucks, commandeered cement silos, vandalized plants and hurled molotov

0:01:18.400 --> 0:01:22.400
<v Speaker 1>cocktails at police. When I asked Wholesom's head of corporate

0:01:22.400 --> 0:01:26.600
<v Speaker 1>communications who the culprits were, she winced. Rather than uttering

0:01:26.640 --> 0:01:29.039
<v Speaker 1>the names of the bomb throwers, she steered me to

0:01:29.120 --> 0:01:33.600
<v Speaker 1>a group called h e Ks or HEX. It was

0:01:33.640 --> 0:01:36.600
<v Speaker 1>in the tidy, quiet Zurich office of HEX that I

0:01:36.640 --> 0:01:38.560
<v Speaker 1>heard about the suit that would soon be filed in

0:01:38.600 --> 0:01:44.000
<v Speaker 1>Switzerland by four struggling Indonesians, fishers, farmers and hostile operators

0:01:44.200 --> 0:01:48.600
<v Speaker 1>from tiny Piri Island. HEX, despite the witchy ring to

0:01:48.680 --> 0:01:52.080
<v Speaker 1>its name, is a church based, decidedly non violent aid

0:01:52.200 --> 0:01:57.160
<v Speaker 1>organization funded largely by Swiss taxpayers. It's a crucial partner

0:01:57.200 --> 0:02:00.480
<v Speaker 1>in the international coalition that conceived and backed the LA lawsuit.

0:02:01.160 --> 0:02:04.279
<v Speaker 1>Pari Island sits low in the Java Sea, about twenty

0:02:04.280 --> 0:02:08.720
<v Speaker 1>four miles from Jakarta, the overstuffed sinking capital of Indonesia.

0:02:09.400 --> 0:02:12.320
<v Speaker 1>Home to a single rural village, the island is three

0:02:12.360 --> 0:02:15.600
<v Speaker 1>miles long and a third is wide. Small though it is,

0:02:15.840 --> 0:02:18.160
<v Speaker 1>it's one of the biggest islets among the cluster of

0:02:18.200 --> 0:02:22.880
<v Speaker 1>three hundred and forty two constituting Indonesia's thousand islands. The

0:02:22.960 --> 0:02:25.800
<v Speaker 1>islanders argue wholesome played a part in warming the air

0:02:25.880 --> 0:02:29.600
<v Speaker 1>and water around their homes, and thus in stirring storms,

0:02:29.800 --> 0:02:33.160
<v Speaker 1>shifting currents that once routed fish to their nets, killing

0:02:33.240 --> 0:02:36.720
<v Speaker 1>sea crops they once farmed, flooding homes, and robbing their

0:02:36.840 --> 0:02:39.960
<v Speaker 1>children of a future on the island. The changes, they

0:02:40.000 --> 0:02:43.680
<v Speaker 1>say are driving them to desperation. About eleven percent of

0:02:43.720 --> 0:02:47.160
<v Speaker 1>Parri Island has disappeared in recent years. Most of the

0:02:47.200 --> 0:02:49.639
<v Speaker 1>rest is no more than five feet above sea level

0:02:49.880 --> 0:02:53.440
<v Speaker 1>and will likely be gone by twenty sixty. The islander's

0:02:53.520 --> 0:02:56.160
<v Speaker 1>case involves what might be called a perversion of the

0:02:56.240 --> 0:03:00.320
<v Speaker 1>natural carbon cycle around the globe. Carbon is true apped

0:03:00.320 --> 0:03:04.200
<v Speaker 1>in carbonate rock, particularly limestone, which is by far the

0:03:04.240 --> 0:03:08.440
<v Speaker 1>planet's single greatest store of the element. Absent human intervention,

0:03:08.639 --> 0:03:13.200
<v Speaker 1>this carbon is released slowly over geological time. This process

0:03:13.240 --> 0:03:16.720
<v Speaker 1>regulates the distribution of atmospheric carbon and in turn, the

0:03:16.760 --> 0:03:21.080
<v Speaker 1>temperature of the Earth. The industrialized economy has sped this up.

0:03:21.440 --> 0:03:23.920
<v Speaker 1>In the past one hundred and fifty years, hundreds of

0:03:23.919 --> 0:03:26.840
<v Speaker 1>thousands of years worth of atmospheric carbon has been released.

0:03:27.320 --> 0:03:31.280
<v Speaker 1>Cement manufacture isn't the most heat intensive industrial practice, but

0:03:31.320 --> 0:03:34.760
<v Speaker 1>it's one of them. It uses primarily fossil fuels to

0:03:34.800 --> 0:03:38.680
<v Speaker 1>heat giant furnaces to twenty seven hundred degrees fahrenheit, hot

0:03:38.760 --> 0:03:40.960
<v Speaker 1>enough to cook the carbon out of four point five

0:03:41.040 --> 0:03:45.000
<v Speaker 1>billion tons of limestone annually. About forty percent of the

0:03:45.040 --> 0:03:48.400
<v Speaker 1>cement industry's emissions result from its prodigious use of fuels.

0:03:48.800 --> 0:03:51.960
<v Speaker 1>The bigger share comes from the fugitive carbon released by

0:03:51.960 --> 0:03:55.760
<v Speaker 1>the chemical change that transforms limestone into the main ingredient

0:03:55.880 --> 0:03:59.600
<v Speaker 1>in cement. The cement industry produces seven to eight percent

0:03:59.640 --> 0:04:03.760
<v Speaker 1>of all human caused carbon emissions. So far, six of

0:04:03.800 --> 0:04:07.480
<v Speaker 1>the thousand islands are no more twenty will likely drown

0:04:07.560 --> 0:04:13.480
<v Speaker 1>over the next few years. Two. The legal climate as

0:04:13.560 --> 0:04:16.680
<v Speaker 1>Mania at Ol versus Wholesome was filed in twenty twenty three,

0:04:17.120 --> 0:04:20.680
<v Speaker 1>and on December seventeenth, twenty twenty five, a cantonal court

0:04:20.800 --> 0:04:23.360
<v Speaker 1>ruled that the bold legal theories behind the case were

0:04:23.440 --> 0:04:26.960
<v Speaker 1>sound and that a trial was warranted. The ruling was

0:04:27.000 --> 0:04:30.640
<v Speaker 1>a bombshell for a number of reasons. Most significantly, the

0:04:30.680 --> 0:04:35.160
<v Speaker 1>Swiss court accepted that individuals harmed by climate change deserve compensation.

0:04:35.800 --> 0:04:39.560
<v Speaker 1>Defendants in similar cases have in the past argued successfully

0:04:39.600 --> 0:04:42.800
<v Speaker 1>that individuals who suffer harm from climate change don't warrant

0:04:42.839 --> 0:04:46.240
<v Speaker 1>special consideration because everyone in the world deals with the

0:04:46.279 --> 0:04:49.520
<v Speaker 1>same climate reality, so it's a political issue at best.

0:04:50.160 --> 0:04:53.760
<v Speaker 1>The court, however, ruled that because Swiss law protects individual's

0:04:53.839 --> 0:04:58.600
<v Speaker 1>physical integrity, health and personal freedom, the islanders deserved compensation

0:04:58.760 --> 0:05:02.240
<v Speaker 1>for any direct harm they suffered. The court accepted that

0:05:02.320 --> 0:05:05.440
<v Speaker 1>climate policy is a matter for politics, but it ruled

0:05:05.480 --> 0:05:10.160
<v Speaker 1>that private lawsuits complement legislation, and though Wholesome hasn't operated

0:05:10.200 --> 0:05:13.760
<v Speaker 1>in Indonesia since twenty nineteen, the court is allowing the

0:05:13.880 --> 0:05:17.640
<v Speaker 1>argument that the harms of Wholesom's cumulative worldwide emissions were

0:05:17.720 --> 0:05:21.719
<v Speaker 1>unbounded by geography, and that even distant sufferers were entitled

0:05:21.720 --> 0:05:25.760
<v Speaker 1>to compensation from the company. When the case is finally heard,

0:05:25.880 --> 0:05:29.000
<v Speaker 1>the court will weigh the science that connects Wholesom's omissions

0:05:29.040 --> 0:05:32.719
<v Speaker 1>to climate change around Pari Island. At that stage, things

0:05:32.839 --> 0:05:36.080
<v Speaker 1>may not go the islander's way, but the progress already

0:05:36.080 --> 0:05:39.360
<v Speaker 1>made suggests the court's may ring changes from industry where

0:05:39.400 --> 0:05:43.680
<v Speaker 1>political action has faltered. Following the December ruling, thirty nine

0:05:43.720 --> 0:05:47.279
<v Speaker 1>Pakistani farmers filed a lawsuit in Germany against two companies,

0:05:47.720 --> 0:05:53.080
<v Speaker 1>including Wholesom's chief European rival, Heidelberg Materials, seeking partial compensation

0:05:53.279 --> 0:05:56.919
<v Speaker 1>for the loss of homes and livelihoods caused by devastating floods.

0:05:57.480 --> 0:06:00.480
<v Speaker 1>The wholesome case in effect puts the whole world production

0:06:00.600 --> 0:06:04.520
<v Speaker 1>and use of cement and concrete on trial. The vast

0:06:04.600 --> 0:06:08.360
<v Speaker 1>majority of the world's cement is Portland cement, a manufactured

0:06:08.440 --> 0:06:12.680
<v Speaker 1>chemical powder that's the crucial binding ingredient in most modern concrete.

0:06:13.000 --> 0:06:15.839
<v Speaker 1>Cement usually makes up ten percent to fifteen percent of

0:06:15.880 --> 0:06:19.279
<v Speaker 1>the volume in a basic concrete mix. The rest includes

0:06:19.400 --> 0:06:23.920
<v Speaker 1>hard bits called aggregate, usually stones of various sizes, and sand,

0:06:24.520 --> 0:06:26.880
<v Speaker 1>and the ingredient that kicks off the binding of it

0:06:26.960 --> 0:06:31.720
<v Speaker 1>all together. Water. Portland's cement was patented by Joseph Aspden

0:06:31.800 --> 0:06:35.960
<v Speaker 1>in England in eighteen twenty four. Aspden took dubious credit

0:06:36.040 --> 0:06:38.960
<v Speaker 1>for its invention, but he gave the smoky gray material

0:06:39.000 --> 0:06:42.640
<v Speaker 1>its durable name, meant to invoke a posh similarly colored

0:06:42.680 --> 0:06:46.240
<v Speaker 1>stone quarried on the isle of Portland. Today, cement and

0:06:46.320 --> 0:06:48.719
<v Speaker 1>the concrete made with it are the world's most widely

0:06:48.839 --> 0:06:52.080
<v Speaker 1>used human made materials, amounting to a one point four

0:06:52.160 --> 0:06:56.760
<v Speaker 1>trillion dollar global market. They enable modern living. They're deployed

0:06:56.760 --> 0:07:00.159
<v Speaker 1>to address almost every major human and natural challenge and

0:07:00.240 --> 0:07:04.159
<v Speaker 1>deliver immeasurable benefits, including a healthier, longer life for people

0:07:04.240 --> 0:07:08.000
<v Speaker 1>almost everywhere. But this progress has come at a cost

0:07:08.040 --> 0:07:11.800
<v Speaker 1>to the climate. At Wholesom's peak, the company has bought, sold,

0:07:11.840 --> 0:07:15.480
<v Speaker 1>and merged divisions often. It operated in ninety countries and

0:07:15.640 --> 0:07:19.000
<v Speaker 1>was the market leader in forty. The Pyre Islanders and

0:07:19.040 --> 0:07:22.080
<v Speaker 1>their backers assert that the company has produced point forty

0:07:22.120 --> 0:07:26.320
<v Speaker 1>two percent of all industrial CO two emissions since seventeen fifty,

0:07:26.880 --> 0:07:29.400
<v Speaker 1>so they're asking it to pay point forty two percent

0:07:29.440 --> 0:07:32.440
<v Speaker 1>of the damages caused to them and their families. The

0:07:32.560 --> 0:07:36.400
<v Speaker 1>requested sum, around twenty thousand dollars, would be a pittance

0:07:36.440 --> 0:07:39.000
<v Speaker 1>to a company with a market capitalization of fifty one

0:07:39.000 --> 0:07:43.240
<v Speaker 1>billion dollars, but Wholesom's lawyers have argued, using an apt metaphor,

0:07:43.560 --> 0:07:46.200
<v Speaker 1>that a ruling in favor of the plaintiffs would open

0:07:46.240 --> 0:07:50.320
<v Speaker 1>the floodgates to an endless queue of claimants. The islander's

0:07:50.440 --> 0:07:53.560
<v Speaker 1>non financial demands could be far more onerous for Wholesome.

0:07:54.000 --> 0:07:56.600
<v Speaker 1>The suit asks the court to require the company, which

0:07:56.600 --> 0:07:59.800
<v Speaker 1>has committed to eliminating all its carbon emissions by twenty fifty,

0:08:00.120 --> 0:08:03.680
<v Speaker 1>to roughly double the speed of its decarbonization by cutting

0:08:03.680 --> 0:08:07.160
<v Speaker 1>emissions forty three percent by twenty thirty and sixty nine

0:08:07.200 --> 0:08:10.960
<v Speaker 1>percent by twenty forty. Those figures matched the global reduction

0:08:11.040 --> 0:08:15.400
<v Speaker 1>targets established by the United Nations Intergovernmental Panel on Climate Change.

0:08:15.960 --> 0:08:18.720
<v Speaker 1>It also asks the court to compel Wholesome to cap

0:08:18.840 --> 0:08:23.600
<v Speaker 1>not only per volume emissions but also overall emissions. Wholesome,

0:08:23.840 --> 0:08:27.040
<v Speaker 1>like other cement makers, measures its success at cutting emissions

0:08:27.040 --> 0:08:29.920
<v Speaker 1>by counting the CO two released for a given volume

0:08:29.960 --> 0:08:33.840
<v Speaker 1>of cement produced. That leaves room for overall emissions to climb.

0:08:33.840 --> 0:08:37.240
<v Speaker 1>If sales of cement outpaced the per volume reductions, the

0:08:37.320 --> 0:08:40.040
<v Speaker 1>suit could impede the company's efforts to sell more cement

0:08:40.120 --> 0:08:44.800
<v Speaker 1>and grab market share amid its industry's ongoing consolidation. Prior

0:08:44.840 --> 0:08:48.160
<v Speaker 1>to the December ruling, Wholesom argued that mandating limits on

0:08:48.200 --> 0:08:50.800
<v Speaker 1>its output would be meaningless for the islanders and the

0:08:50.800 --> 0:08:53.760
<v Speaker 1>climate because other companies would provide the market with what

0:08:53.840 --> 0:08:58.040
<v Speaker 1>Wholesome couldn't. The Court reasoned that the opposite would be true. Rather,

0:08:58.160 --> 0:09:01.640
<v Speaker 1>it said, other co two would probably also have to

0:09:01.720 --> 0:09:04.760
<v Speaker 1>expect to be held accountable for their emissions. The threat

0:09:04.760 --> 0:09:07.400
<v Speaker 1>of an injunction may cause other actors in the cement

0:09:07.480 --> 0:09:11.680
<v Speaker 1>and concrete industry to reduce their emissions. Wholesome is a

0:09:11.720 --> 0:09:15.280
<v Speaker 1>bell weather in its industry. It wields formidable influence in

0:09:15.320 --> 0:09:18.560
<v Speaker 1>the trade associations and with governmental and other bodies that

0:09:18.600 --> 0:09:22.560
<v Speaker 1>set standards for cementing concrete. A final judgment in favor

0:09:22.600 --> 0:09:25.120
<v Speaker 1>of the Islanders would likely set in motion a test

0:09:25.160 --> 0:09:28.400
<v Speaker 1>of whether the cement industry can decarbonize far faster than

0:09:28.400 --> 0:09:31.640
<v Speaker 1>it claims as possible. Some of this could be accomplished

0:09:31.640 --> 0:09:35.040
<v Speaker 1>through new methods of building with less material Some could

0:09:35.160 --> 0:09:39.439
<v Speaker 1>entail accelerating the development of carbon negative materials which absorb

0:09:39.559 --> 0:09:42.920
<v Speaker 1>or sequester co too rather than emit it. That would

0:09:43.000 --> 0:09:46.520
<v Speaker 1>change how the world uses its favorite material. Because of

0:09:46.559 --> 0:09:49.000
<v Speaker 1>the unrivaled scale of its use and the pace of

0:09:49.000 --> 0:09:52.040
<v Speaker 1>innovation in the sector, concrete may prove to be the

0:09:52.040 --> 0:09:55.600
<v Speaker 1>most essential material for dialing back carbon dioxide emissions of

0:09:55.640 --> 0:09:59.679
<v Speaker 1>all kinds. In a twist, the Pari Islanders are suing

0:09:59.720 --> 0:10:02.080
<v Speaker 1>one of the the cement companies that's pushed the hardest

0:10:02.080 --> 0:10:05.640
<v Speaker 1>to decarbonize and spoken the loudest about the economic sense

0:10:05.679 --> 0:10:08.960
<v Speaker 1>of doing so. Over the past five years, Wholesome has

0:10:09.000 --> 0:10:12.240
<v Speaker 1>been remaking its business in service of governmental and corporate

0:10:12.240 --> 0:10:15.880
<v Speaker 1>sustainability goals. The optimistic case for the climate is that,

0:10:16.280 --> 0:10:20.120
<v Speaker 1>rather than handcuffing the company, the four Indonesian Islanders could

0:10:20.160 --> 0:10:23.160
<v Speaker 1>end up propelling its business into a new phase and

0:10:23.200 --> 0:10:28.480
<v Speaker 1>igniting a profound change for the planet. Three tropical Swiss

0:10:29.320 --> 0:10:33.880
<v Speaker 1>Hexa's office is in Cyric's quiet leafy Untustras neighborhood, set

0:10:33.920 --> 0:10:36.800
<v Speaker 1>among a mix of late nineteenth century Art Nouveaux homes,

0:10:37.080 --> 0:10:40.840
<v Speaker 1>mid century apartment houses, and university halls. It's hard to

0:10:40.840 --> 0:10:43.240
<v Speaker 1>walk the streets of a Swiss city and not marvel

0:10:43.280 --> 0:10:46.760
<v Speaker 1>at the country's use of concrete. Its engineers pioneered new

0:10:46.760 --> 0:10:50.360
<v Speaker 1>applications for the material throughout the twentieth century, and modern

0:10:50.480 --> 0:10:54.360
<v Speaker 1>concrete architecture took root there too, including the unfinished or

0:10:54.520 --> 0:10:58.600
<v Speaker 1>brute concrete that Le Corbusier championed, which spurred the rise

0:10:58.640 --> 0:11:02.840
<v Speaker 1>of brutalism. There's nothing brutish about it. Swiss workers are

0:11:02.880 --> 0:11:06.240
<v Speaker 1>among the world's best finishers of concrete, and the surfaces

0:11:06.280 --> 0:11:10.079
<v Speaker 1>on modern homes, schools, and offices are exquisite. The city

0:11:10.080 --> 0:11:14.440
<v Speaker 1>blocks around HEX are dotted with fine examples. HEX is

0:11:14.480 --> 0:11:17.520
<v Speaker 1>headquartered in a linear, blue and white office building circa

0:11:17.559 --> 0:11:21.400
<v Speaker 1>nineteen sixty three, with cargo bicycles at the door. I

0:11:21.520 --> 0:11:24.000
<v Speaker 1>arrived from my first visit back in twenty twenty two

0:11:24.200 --> 0:11:27.200
<v Speaker 1>during a coffee break and was led through angular modern

0:11:27.240 --> 0:11:30.959
<v Speaker 1>offices to a sitting area. There, casually dressed workers sat

0:11:31.000 --> 0:11:33.800
<v Speaker 1>around a low table, quietly enjoying drinks and a bowl

0:11:33.840 --> 0:11:37.160
<v Speaker 1>of pears and grapes. We don't talk about work during

0:11:37.200 --> 0:11:40.040
<v Speaker 1>these breaks, I was told, as the bowl came my way,

0:11:40.840 --> 0:11:43.920
<v Speaker 1>no evidence of bomb throwers here. Had the staff not

0:11:43.960 --> 0:11:46.880
<v Speaker 1>been speaking Swiss German, the office might have been mistaken

0:11:46.920 --> 0:11:49.720
<v Speaker 1>for the city hall of an affluent, progressive town somewhere

0:11:49.720 --> 0:11:53.760
<v Speaker 1>in say, the Pacific Northwest. Following the break, the workers

0:11:53.800 --> 0:11:57.640
<v Speaker 1>headed uninterrupted to their desks. Part of hex's mission is

0:11:57.679 --> 0:12:01.000
<v Speaker 1>to redress inequities between the affluent glos global North and

0:12:01.040 --> 0:12:04.720
<v Speaker 1>the poorer global South. On the office shelves were report

0:12:04.760 --> 0:12:08.720
<v Speaker 1>covers showing people stooping in fields to harvest crops, squatting

0:12:08.760 --> 0:12:12.960
<v Speaker 1>next to wells, wading through floods, carrying food to refugee tents,

0:12:13.320 --> 0:12:16.640
<v Speaker 1>or cupping seeds and beans in their hands. Good works,

0:12:17.120 --> 0:12:20.960
<v Speaker 1>God's work. I was there to discuss hex's views of

0:12:21.000 --> 0:12:24.560
<v Speaker 1>Switzerland's cement industry. I didn't yet know about the Pari

0:12:24.600 --> 0:12:27.920
<v Speaker 1>Island case, and it might have gone unmentioned. Following a

0:12:27.920 --> 0:12:31.240
<v Speaker 1>general overview on the dangers of carbon emissions, I was

0:12:31.280 --> 0:12:35.000
<v Speaker 1>told that HEX viewed Wholesome's green strategies as suspect and

0:12:35.040 --> 0:12:38.240
<v Speaker 1>that the company's public messaging masked a go slow approach.

0:12:38.800 --> 0:12:40.920
<v Speaker 1>On the way out, I noticed a poster of a

0:12:40.960 --> 0:12:44.559
<v Speaker 1>group in Indonesia. They wore the distinctive prints and headscarves

0:12:44.600 --> 0:12:46.880
<v Speaker 1>I knew from living and working in that country on

0:12:47.000 --> 0:12:49.880
<v Speaker 1>and off since the nineteen eighties. I asked about this

0:12:49.960 --> 0:12:52.560
<v Speaker 1>group and heard for the first time the story of

0:12:52.600 --> 0:12:56.079
<v Speaker 1>the Pari Islanders. Last summer, as I prepared for a

0:12:56.160 --> 0:12:59.240
<v Speaker 1>visit to Jakarta, I called Hex to see if anything

0:12:59.320 --> 0:13:02.560
<v Speaker 1>was stirring. My timing was good. I was told a

0:13:02.600 --> 0:13:06.600
<v Speaker 1>hearing was scheduled in soog for September. The Indonesians would

0:13:06.640 --> 0:13:09.080
<v Speaker 1>be coming to Switzerland to face Wholesome in person for

0:13:09.120 --> 0:13:12.120
<v Speaker 1>the first time. I told Hex, I'd like to interview

0:13:12.160 --> 0:13:14.559
<v Speaker 1>the plaintiffs there, but first I'd like to see them

0:13:14.600 --> 0:13:17.640
<v Speaker 1>on Pari Island. I could even speak to them in Indonesian,

0:13:17.880 --> 0:13:20.360
<v Speaker 1>especially if I had a translator for back up. We

0:13:20.480 --> 0:13:26.200
<v Speaker 1>had a deal four David and Goliath, Daoud and Jalout.

0:13:27.080 --> 0:13:30.880
<v Speaker 1>Parid Ridwanoudon was one of my first contacts. Parid is

0:13:30.920 --> 0:13:33.760
<v Speaker 1>a stout, energetic activist with a history of fighting for

0:13:33.840 --> 0:13:37.960
<v Speaker 1>small island fishers whose catches are threatened by mass excavations

0:13:38.000 --> 0:13:41.760
<v Speaker 1>by sand miners feeding the regions in satiable appetites for concrete,

0:13:41.760 --> 0:13:45.480
<v Speaker 1>aggregate and landfill material. There are no hard and fast

0:13:45.559 --> 0:13:49.000
<v Speaker 1>rules for citing Indonesian names in the press. I've adopted

0:13:49.000 --> 0:13:52.520
<v Speaker 1>the names the people themselves prefer. He lives in Jakarta

0:13:52.800 --> 0:13:55.920
<v Speaker 1>and works with the Indonesian Forum for Living Environment or

0:13:55.960 --> 0:13:59.400
<v Speaker 1>While He an environmental organization affiliated with Friends of the

0:13:59.440 --> 0:14:03.360
<v Speaker 1>Earth Internet. When the Swiss case first took shape, he

0:14:03.440 --> 0:14:05.679
<v Speaker 1>was enlisted to work with the Pari Islanders and their

0:14:05.720 --> 0:14:09.880
<v Speaker 1>European backers, organizing a public campaign and acting as an

0:14:09.920 --> 0:14:13.200
<v Speaker 1>English language interpreter for the plaintiffs. The main point of

0:14:13.240 --> 0:14:16.400
<v Speaker 1>the lawsuit is to focus on major carbon emitters, Piede

0:14:16.440 --> 0:14:18.720
<v Speaker 1>told me this is to send a message to the

0:14:18.720 --> 0:14:22.000
<v Speaker 1>global community that the fate of the Pari Islanders has

0:14:22.040 --> 0:14:24.960
<v Speaker 1>a connection to the global climate movement and is linked

0:14:25.000 --> 0:14:28.480
<v Speaker 1>to previous climate lawsuits. For while he Hex and the

0:14:28.520 --> 0:14:32.760
<v Speaker 1>European Center for Constitutional and Human Rights in Berlin, another backer.

0:14:32.920 --> 0:14:35.280
<v Speaker 1>The suit against Wholesome is part of a larger effort

0:14:35.400 --> 0:14:39.360
<v Speaker 1>by global non governmental organizations to hold to account big

0:14:39.400 --> 0:14:43.160
<v Speaker 1>emitters and the governments that failed to sufficiently curb them.

0:14:43.520 --> 0:14:46.520
<v Speaker 1>The case was brought in Switzerland in part because Indonesian

0:14:46.600 --> 0:14:50.360
<v Speaker 1>law leaves little room for climate lawsuits. Targeting a Swiss

0:14:50.400 --> 0:14:53.800
<v Speaker 1>company that no longer does business in Indonesia also allowed

0:14:53.800 --> 0:14:59.120
<v Speaker 1>the activists to sidestep some especially challenging political issues. Indonesia's

0:14:59.120 --> 0:15:02.880
<v Speaker 1>biggest carbon ima, including in the cement sector, are deeply

0:15:02.880 --> 0:15:07.760
<v Speaker 1>connected to the government. Among national legal systems, Indonesia's notoriously

0:15:07.800 --> 0:15:10.720
<v Speaker 1>corrupt courts rank a low sixty ninth in heeding the

0:15:10.840 --> 0:15:14.480
<v Speaker 1>rule of law. According to the World Justice Project. Swiss

0:15:14.560 --> 0:15:17.080
<v Speaker 1>courts might be half a world away, but they rank

0:15:17.120 --> 0:15:20.960
<v Speaker 1>among the least corrupt. When while he and Hex started

0:15:21.000 --> 0:15:25.840
<v Speaker 1>recruiting plaintiffs, many Pari Islanders came forward to volunteer, Slowly,

0:15:26.000 --> 0:15:30.160
<v Speaker 1>most dropped out, and only the four persevered. The story

0:15:30.240 --> 0:15:33.840
<v Speaker 1>is very good with the Daoud and Jalut element, says Pared,

0:15:34.280 --> 0:15:37.720
<v Speaker 1>invoking the Quran's version of David and Goliath. His role

0:15:37.760 --> 0:15:39.360
<v Speaker 1>in the case is to make the most of the

0:15:39.480 --> 0:15:42.640
<v Speaker 1>archetype with a bit of ayoub, the Islamic counterpart to

0:15:42.720 --> 0:15:49.480
<v Speaker 1>job thrown in five. How concrete disappears. Natives of concrete

0:15:49.480 --> 0:15:53.120
<v Speaker 1>places often don't notice how pervasive the stuff is. One

0:15:53.160 --> 0:15:57.040
<v Speaker 1>reason may be that humans are cognitive misers. We're wired

0:15:57.040 --> 0:16:00.440
<v Speaker 1>to edit out complications. We edit out conos crete from

0:16:00.440 --> 0:16:03.040
<v Speaker 1>our view the way we edit out our noses, though

0:16:03.040 --> 0:16:06.480
<v Speaker 1>they're both nearly always in our field of vision. Almost

0:16:06.560 --> 0:16:09.400
<v Speaker 1>every building erected in the past seventy five years in

0:16:09.440 --> 0:16:13.160
<v Speaker 1>an industrialized country has at the least a concrete foundation

0:16:13.640 --> 0:16:18.040
<v Speaker 1>and very likely concrete floors. Concrete can seem the dead

0:16:18.120 --> 0:16:22.320
<v Speaker 1>opposite of sexy architecture. Critic John Goodman notes that in

0:16:22.360 --> 0:16:26.680
<v Speaker 1>its raw form, it presents as primitive, even scatological, oozing

0:16:26.720 --> 0:16:29.600
<v Speaker 1>down the shoot of a mixer truck. Frank Lloyd Wright,

0:16:29.680 --> 0:16:34.080
<v Speaker 1>who used concrete beautifully the Guggenheim, wrestled with the material's

0:16:34.160 --> 0:16:39.280
<v Speaker 1>earth and blandness, calling cement characterless and concrete artificial stone

0:16:39.280 --> 0:16:43.320
<v Speaker 1>at best and a petrified sand heap at worst. Concrete

0:16:43.360 --> 0:16:48.720
<v Speaker 1>can be dull, hard, inert. Paradoxically, these very qualities have

0:16:48.840 --> 0:16:51.920
<v Speaker 1>made it one of the most transformative materials ever created.

0:16:52.560 --> 0:16:56.080
<v Speaker 1>The world has been remade with it. Measured by mass,

0:16:56.160 --> 0:16:58.800
<v Speaker 1>About half of the world's more than one trillion tons

0:16:58.840 --> 0:17:02.280
<v Speaker 1>of human made stuff is concrete. Most of that has

0:17:02.320 --> 0:17:06.080
<v Speaker 1>appeared in the past fifty years. In the late nineteenth century,

0:17:06.240 --> 0:17:10.040
<v Speaker 1>concrete was a niche product compared with other materials. It

0:17:10.119 --> 0:17:13.520
<v Speaker 1>was too expensive and inconsistent for most jobs in a

0:17:13.600 --> 0:17:16.879
<v Speaker 1>largely wood and masonry world. It was reserved mainly for

0:17:16.960 --> 0:17:21.000
<v Speaker 1>infrastructure projects, sewer systems, canals, the base of the Statue

0:17:21.000 --> 0:17:25.439
<v Speaker 1>of Liberty, and kept out of building architecture. Thomas Edison

0:17:25.480 --> 0:17:29.120
<v Speaker 1>helped change that. In nineteen o two, he applied lessons

0:17:29.119 --> 0:17:31.919
<v Speaker 1>from a failed iron milling business to the creation of

0:17:31.960 --> 0:17:34.920
<v Speaker 1>one hundred and fifty foot long rotary kilns that could

0:17:34.920 --> 0:17:39.240
<v Speaker 1>produce cement in large volumes continuously. He then created one

0:17:39.240 --> 0:17:42.399
<v Speaker 1>of the largest cement plants in the world in New Village,

0:17:42.440 --> 0:17:45.960
<v Speaker 1>New Jersey. The Edison Portland Cement Company's new method of

0:17:46.000 --> 0:17:50.440
<v Speaker 1>mass production turned Portland cement from an expensive, uncommon material

0:17:50.760 --> 0:17:55.800
<v Speaker 1>into an industrialized, abundant, affordable one. Edison tried unsuccessfully to

0:17:55.880 --> 0:17:59.600
<v Speaker 1>market single family concrete homes made by pouring the material

0:17:59.640 --> 0:18:03.399
<v Speaker 1>into a house size mold, but the equipment proved too expensive.

0:18:03.920 --> 0:18:07.040
<v Speaker 1>His cement company also failed, in part because a rash

0:18:07.080 --> 0:18:11.040
<v Speaker 1>of cement makers quickly adopted the technology he pioneered, creating

0:18:11.040 --> 0:18:15.320
<v Speaker 1>an oversupply that drove down prices. But the urbanizing, motorized,

0:18:15.400 --> 0:18:19.480
<v Speaker 1>electric and fossil fuel powered economy Edison helped create was

0:18:19.640 --> 0:18:23.439
<v Speaker 1>ripe for concrete. Last year, the world used close to

0:18:23.520 --> 0:18:26.919
<v Speaker 1>four billion tons of cement to produce about thirty billion

0:18:26.960 --> 0:18:30.320
<v Speaker 1>tons of concrete, three to four tons for everyone on

0:18:30.400 --> 0:18:34.320
<v Speaker 1>the planet. If Mick Jagger and Keith Richards, both eighty

0:18:34.320 --> 0:18:37.920
<v Speaker 1>two together were delivered there, per capita allotments, it would

0:18:37.960 --> 0:18:42.120
<v Speaker 1>take thirty four concrete trucks Portland. Cement is produced by

0:18:42.160 --> 0:18:45.440
<v Speaker 1>more than twelve hundred companies and thirty five hundred plants

0:18:45.440 --> 0:18:48.280
<v Speaker 1>in one hundred and sixty three countries, though ten of

0:18:48.280 --> 0:18:51.919
<v Speaker 1>the biggest producers, some state owned in China, account for

0:18:51.920 --> 0:18:54.800
<v Speaker 1>forty percent of the global supply. At the time the

0:18:54.880 --> 0:18:59.960
<v Speaker 1>lawsuit was filed, Wholesome was the biggest non Chinese producer.

0:19:00.080 --> 0:19:03.720
<v Speaker 1>Of most big challenges humankind faces, and you'll find we're

0:19:03.840 --> 0:19:07.480
<v Speaker 1>likely to face them with concrete habitation, of course, as

0:19:07.520 --> 0:19:09.639
<v Speaker 1>more than ninety percent of the world's new homes are

0:19:09.640 --> 0:19:12.800
<v Speaker 1>made with it. Most every office building and factory is

0:19:12.920 --> 0:19:16.440
<v Speaker 1>two pick up. Almost anything that was mass produced mechanically

0:19:16.720 --> 0:19:19.720
<v Speaker 1>a pen, a spoon, a circuit board, a motor, and

0:19:19.880 --> 0:19:23.280
<v Speaker 1>concrete was under the machine that made it. The gargantuan

0:19:23.359 --> 0:19:26.679
<v Speaker 1>machinery in steel mills must be anchored to concrete foundations

0:19:26.680 --> 0:19:29.919
<v Speaker 1>to hold it steady. Reciprocally, about one fifth of the

0:19:29.920 --> 0:19:34.720
<v Speaker 1>world's steel is used to reinforce concrete, and modern transportation

0:19:34.960 --> 0:19:38.400
<v Speaker 1>happens on concrete. There are three hundred and forty thousand

0:19:38.480 --> 0:19:41.480
<v Speaker 1>concrete bridges in the US and more than eight hundred

0:19:41.520 --> 0:19:45.080
<v Speaker 1>thousand in China. Canals, ports and airports are among the

0:19:45.119 --> 0:19:49.560
<v Speaker 1>most concrete intensive structures of all. Concrete is an almost

0:19:49.600 --> 0:19:53.400
<v Speaker 1>miraculous contributor to public health. It enabled the build out

0:19:53.480 --> 0:19:56.840
<v Speaker 1>of municipal systems that deliver safe drinking water and remove

0:19:56.880 --> 0:20:01.439
<v Speaker 1>and process waste. Concrete pipes and storm basins detain rushing

0:20:01.480 --> 0:20:05.879
<v Speaker 1>waters that would otherwise flood streets and homes with road grime, toxins, trash,

0:20:05.920 --> 0:20:09.359
<v Speaker 1>and sewer rats. When in poor neighborhoods and crowded Latin

0:20:09.400 --> 0:20:14.880
<v Speaker 1>American cities, Concrete replaces dirt floors, Parasitic infestations and anemia

0:20:14.960 --> 0:20:18.560
<v Speaker 1>in children both drop by around eighty percent, and cases

0:20:18.600 --> 0:20:23.080
<v Speaker 1>of diarrhea nearly have. A programme in Mexico called Piezoferme

0:20:23.440 --> 0:20:26.760
<v Speaker 1>Solid Floor installed concrete floors in the homes of more

0:20:26.800 --> 0:20:30.280
<v Speaker 1>than two point seven million families. It did more for

0:20:30.400 --> 0:20:35.160
<v Speaker 1>children's overall health than food aid or nutritional supplements. Concrete

0:20:35.200 --> 0:20:40.240
<v Speaker 1>isn't necessary for human reproduction. Indonesian readers kindly resist puns

0:20:40.280 --> 0:20:43.399
<v Speaker 1>with semen your word for cement, but its use in

0:20:43.520 --> 0:20:48.520
<v Speaker 1>hygienic maternity wards lowers infections and infant mortality. The world's

0:20:48.600 --> 0:20:54.200
<v Speaker 1>energy infrastructure, including dams, nuclear plants, and renewables, is heavily concrete.

0:20:54.560 --> 0:20:57.440
<v Speaker 1>It's the only affordable material with enough mass to hold

0:20:57.440 --> 0:21:01.119
<v Speaker 1>the towers of big wind turbines steady against gravity, torque,

0:21:01.160 --> 0:21:05.080
<v Speaker 1>and wind shear. Smaller turbine towers, the kind that dot

0:21:05.160 --> 0:21:09.000
<v Speaker 1>cornfields in the American Midwest each stand in one thousand

0:21:09.080 --> 0:21:13.360
<v Speaker 1>to two thousand tons of concrete. Newer nuclear plants use

0:21:13.440 --> 0:21:18.359
<v Speaker 1>seven hundred thousand tons of concrete. China's Midog hydropower station

0:21:18.640 --> 0:21:22.480
<v Speaker 1>and related infrastructure in Tibet is slated to begin operating

0:21:22.520 --> 0:21:25.760
<v Speaker 1>in twenty thirty three, it will be by far the

0:21:25.800 --> 0:21:30.080
<v Speaker 1>world's largest power plant, generating enough daily power for three

0:21:30.200 --> 0:21:33.680
<v Speaker 1>hundred million people. It will also be the world's most

0:21:33.720 --> 0:21:38.000
<v Speaker 1>massive concrete structure, built with an estimated three hundred million

0:21:38.160 --> 0:21:42.960
<v Speaker 1>tons worth. The security and defense industries depend on concrete. Two.

0:21:43.520 --> 0:21:46.639
<v Speaker 1>In twenty sixteen, the Modern War Institute at West Point

0:21:46.960 --> 0:21:51.399
<v Speaker 1>identified concrete, not weapons or vehicles or computers, as the U. S.

0:21:51.520 --> 0:21:56.399
<v Speaker 1>Army's most important strategic battle asset. The overarching fact about

0:21:56.440 --> 0:21:59.919
<v Speaker 1>concrete is that it's unavoidable, and the more it's used,

0:22:00.119 --> 0:22:03.679
<v Speaker 1>the more its use expands. Concrete is the material that

0:22:03.800 --> 0:22:10.840
<v Speaker 1>networks almost every other built network. Six. Escaping Jakarta. My

0:22:10.960 --> 0:22:13.320
<v Speaker 1>trip to the boat for Pari Island began with an

0:22:13.320 --> 0:22:16.760
<v Speaker 1>early morning taxi ride across Jakarta through a cityscape of

0:22:16.840 --> 0:22:21.159
<v Speaker 1>concrete and little els. Jakarta anchors the world's most populous

0:22:21.200 --> 0:22:25.679
<v Speaker 1>metro region, with forty two million people. Its surpassed Tokyos.

0:22:26.359 --> 0:22:29.000
<v Speaker 1>Although it sits in the tropics, it's wofully short of

0:22:29.040 --> 0:22:32.320
<v Speaker 1>green spaces. Ninety percent of its surface is paved or

0:22:32.400 --> 0:22:37.359
<v Speaker 1>otherwise concretised. Jakarta is the fastest sinking large city in

0:22:37.400 --> 0:22:40.680
<v Speaker 1>the world. It drops ten to thirty centimeters a year,

0:22:40.840 --> 0:22:44.080
<v Speaker 1>depending on the neighborhood. Two thirds of the city's water

0:22:44.200 --> 0:22:48.200
<v Speaker 1>is drawn from the ground below. Draining the groundwater compacts

0:22:48.200 --> 0:22:52.200
<v Speaker 1>the soil. The weight of Jakarta's buildings compacts it even more.

0:22:53.080 --> 0:22:58.159
<v Speaker 1>My car crawled through infamously choked city streets. Jakartans stuck

0:22:58.160 --> 0:23:01.920
<v Speaker 1>in traffic like to say they're study patients. The pace

0:23:02.000 --> 0:23:04.760
<v Speaker 1>finally accelerated as the car climbed a ramp to one

0:23:04.760 --> 0:23:08.360
<v Speaker 1>of the city's elevated highways. Above were the upper floors

0:23:08.359 --> 0:23:12.080
<v Speaker 1>of huge apartment towers, clustered into complexes that house tens

0:23:12.080 --> 0:23:15.320
<v Speaker 1>of thousands of people. Below lay a street level city

0:23:15.560 --> 0:23:19.720
<v Speaker 1>that's a perennially half built crush of homes, shops, mosques,

0:23:19.720 --> 0:23:23.000
<v Speaker 1>big and small food stalls, and the largest collection of

0:23:23.040 --> 0:23:26.560
<v Speaker 1>indoor malls of any city in the world. Across from

0:23:26.560 --> 0:23:29.640
<v Speaker 1>ankoal Port and the boat to the island were both

0:23:29.760 --> 0:23:34.080
<v Speaker 1>soaring modern buildings and the abandoned concrete skeletons of unfinished

0:23:34.119 --> 0:23:38.440
<v Speaker 1>apartment towers. The spongy land beneath couldn't support their weight.

0:23:39.040 --> 0:23:41.879
<v Speaker 1>The city is a hodgepodge of concrete done well and

0:23:41.960 --> 0:23:47.960
<v Speaker 1>concrete squandered locals sometimes crave an escape from the concrete everywhere,

0:23:48.240 --> 0:23:51.480
<v Speaker 1>and Pari Island makes for a quaint time out the boat.

0:23:51.520 --> 0:23:54.600
<v Speaker 1>Trip to the island can take one, two or three hours,

0:23:54.640 --> 0:23:57.280
<v Speaker 1>depending on whether you travel by a small bouncy boat

0:23:57.280 --> 0:23:59.920
<v Speaker 1>with a modest engine, a medium sized boat that makes

0:24:00.119 --> 0:24:02.720
<v Speaker 1>stop at a mall, or a fast boat that crashes

0:24:02.760 --> 0:24:06.080
<v Speaker 1>through the waves, soaks the passengers and is crushingly. Loud

0:24:06.800 --> 0:24:09.879
<v Speaker 1>I took the two hour trip the boat past the

0:24:09.960 --> 0:24:13.600
<v Speaker 1>remains of centuries old derelict Dutch forts that still dominate

0:24:13.680 --> 0:24:16.600
<v Speaker 1>several of the small islands in the chain. From such

0:24:16.760 --> 0:24:20.880
<v Speaker 1>hulking structures, some with walls twelve feet thick, the Netherlands

0:24:20.920 --> 0:24:24.000
<v Speaker 1>subdued its Indonesian colonies for more than three hundred and

0:24:24.040 --> 0:24:27.880
<v Speaker 1>fifty years. The Dutch fashioned a concrete like substance by

0:24:27.920 --> 0:24:31.600
<v Speaker 1>grinding up seashells to make quicklime, similar to that produced

0:24:31.600 --> 0:24:34.840
<v Speaker 1>from limestone in the making of Portland cement today. The

0:24:34.960 --> 0:24:39.600
<v Speaker 1>Dutch also used Indonesia's abundant volcanic ash, a functional double

0:24:39.640 --> 0:24:43.359
<v Speaker 1>of modern cement, and as with modern concrete, combined it

0:24:43.440 --> 0:24:46.560
<v Speaker 1>with sand and rock to make an almost indestructible mass.

0:24:47.480 --> 0:24:50.399
<v Speaker 1>The scenes along the sandy paths that thread through Pirie

0:24:50.480 --> 0:24:53.360
<v Speaker 1>Island appear like a throwback in time to the kind

0:24:53.359 --> 0:24:56.600
<v Speaker 1>of village life ja Cartan families often left behind the

0:24:56.680 --> 0:25:00.800
<v Speaker 1>rural Indonesia of palms, tiny shops, bare feet, no cars.

0:25:01.560 --> 0:25:05.680
<v Speaker 1>Hammocks are slung between palms on the beaches. Seaside stalls,

0:25:05.920 --> 0:25:07.800
<v Speaker 1>many no more than a couple of benches and a

0:25:07.800 --> 0:25:12.440
<v Speaker 1>makeshift table serve grilled fish. Beach volleyball games last past

0:25:12.600 --> 0:25:16.200
<v Speaker 1>dark card games go all night. There are no big

0:25:16.200 --> 0:25:19.520
<v Speaker 1>hotels on the island. Visitors either camp on the beach

0:25:19.720 --> 0:25:22.399
<v Speaker 1>or for twenty five dollars a night, rent a local

0:25:22.480 --> 0:25:24.720
<v Speaker 1>home and fill it with as many family members or

0:25:24.760 --> 0:25:27.960
<v Speaker 1>friends as are willing to pile in. The local term

0:25:28.040 --> 0:25:32.000
<v Speaker 1>for a rented house is homestay. It's odd to think

0:25:32.000 --> 0:25:34.080
<v Speaker 1>of a tourist economy that was borne out of an

0:25:34.080 --> 0:25:38.439
<v Speaker 1>ecological disaster. The shift away from fishing and farming, forced

0:25:38.440 --> 0:25:41.240
<v Speaker 1>by changing seas has brought a measure of low rent

0:25:41.240 --> 0:25:44.840
<v Speaker 1>prosperity to the island, even if the increased flooding brings

0:25:44.960 --> 0:25:49.600
<v Speaker 1>setbacks too. Mustaghfern, locally known as Bobby, is one of

0:25:49.640 --> 0:25:52.720
<v Speaker 1>the four plaintiffs. He's a community leader who as a

0:25:52.800 --> 0:25:57.080
<v Speaker 1>muazin at the local mosque calls worshippers to prayer. He

0:25:57.200 --> 0:26:01.159
<v Speaker 1>was instrumental in kickstarting local tourism worked to keep poshure

0:26:01.280 --> 0:26:06.040
<v Speaker 1>tourism and investors from the island. Bobby lichens Pari Island

0:26:06.119 --> 0:26:09.520
<v Speaker 1>to Jakarta's wartegs or hole in the wall, food stands

0:26:09.560 --> 0:26:14.679
<v Speaker 1>where motorcycle deliverymen, house cleaners, laborers and students sit, smoke

0:26:14.760 --> 0:26:18.600
<v Speaker 1>and linger, ordering curries and satis with their pocket change.

0:26:19.119 --> 0:26:22.359
<v Speaker 1>We're the wartag of resorts, he says. People without a

0:26:22.359 --> 0:26:24.760
<v Speaker 1>lot of money should have a place to go to too.

0:26:25.280 --> 0:26:28.480
<v Speaker 1>Bobby is barely five feet tall, but he's all muscle

0:26:28.640 --> 0:26:32.600
<v Speaker 1>and indefatigable. He created the island's most popular beach by

0:26:32.680 --> 0:26:36.119
<v Speaker 1>himself by clearing brush and debris from about three hundred

0:26:36.200 --> 0:26:39.640
<v Speaker 1>yards of waterfront and creating two more small islands near

0:26:39.680 --> 0:26:43.360
<v Speaker 1>the shore by carting sand over the water as planned.

0:26:43.440 --> 0:26:47.440
<v Speaker 1>The islands are now popular destinations for swimmers and sunset gazers.

0:26:47.920 --> 0:26:51.240
<v Speaker 1>When Bobby tried to collect a voluntary fee equivalent to

0:26:51.280 --> 0:26:54.760
<v Speaker 1>twenty six cents from tourists to help keep the beach tidy,

0:26:55.040 --> 0:26:57.760
<v Speaker 1>he was arrested and jailed for seven months while he

0:26:57.840 --> 0:27:01.280
<v Speaker 1>was prosecuted for extortion. There were rumors that he was

0:27:01.359 --> 0:27:04.199
<v Speaker 1>arrested at the request of developers who considered him an

0:27:04.240 --> 0:27:09.119
<v Speaker 1>impediment to their plans. Bobby was ultimately acquitted. The experience

0:27:09.200 --> 0:27:11.919
<v Speaker 1>proved his metal as a fighter, and for the backers

0:27:11.960 --> 0:27:14.480
<v Speaker 1>of the suit, made him attractive as a plaintiff in

0:27:14.520 --> 0:27:21.720
<v Speaker 1>a battle against Goliath seven. Concrete versus concrete. Until recently,

0:27:22.040 --> 0:27:25.520
<v Speaker 1>Powi Island was all but devoid of concrete, except for

0:27:25.560 --> 0:27:28.159
<v Speaker 1>the fuel that ran the low horsepower motors of the

0:27:28.160 --> 0:27:31.320
<v Speaker 1>island's small fleet of wooden fishing boats, and the fuel

0:27:31.400 --> 0:27:34.680
<v Speaker 1>used to transport the island's crops to Java. The residents

0:27:34.680 --> 0:27:38.399
<v Speaker 1>barely had any carbon footprint at all. Today, however, the

0:27:38.480 --> 0:27:41.960
<v Speaker 1>impact of concrete looms over almost everything on the island,

0:27:42.320 --> 0:27:44.919
<v Speaker 1>a measure of how quickly it can transform a place.

0:27:45.440 --> 0:27:48.520
<v Speaker 1>The islanders have been rushing to elevate their homes, including

0:27:48.560 --> 0:27:52.000
<v Speaker 1>newly built concrete ones, up onto concrete blocks above the

0:27:52.000 --> 0:27:55.920
<v Speaker 1>flood prone ground. Following one of the area's frequent storms,

0:27:56.160 --> 0:28:00.200
<v Speaker 1>Jakarta unleashes an eighteen mile wide flux of filth that

0:28:00.320 --> 0:28:04.000
<v Speaker 1>heads across the open water right toward Pari remnants of

0:28:04.080 --> 0:28:08.400
<v Speaker 1>forty two million residence consumption. Mounds of plastic water bottles,

0:28:08.600 --> 0:28:12.720
<v Speaker 1>old clothes, tires, lengths of rope, tangled fishing net, and

0:28:12.840 --> 0:28:17.639
<v Speaker 1>soggy cardboard creep all over the small island. The garbage

0:28:17.640 --> 0:28:20.960
<v Speaker 1>tide arrives here in part because next door Pulao h

0:28:21.160 --> 0:28:25.000
<v Speaker 1>or h Island has been developed for luxury homes, protected

0:28:25.040 --> 0:28:28.080
<v Speaker 1>by concrete walls that deflect the floe down stream and

0:28:28.200 --> 0:28:32.280
<v Speaker 1>down market. Arrif Pugianto may be the plaintiff, the rising

0:28:32.320 --> 0:28:35.320
<v Speaker 1>seas have punished most. A thin man in his mid

0:28:35.400 --> 0:28:39.840
<v Speaker 1>fifties aref has an angular face, a wispy mustache, and wide,

0:28:39.880 --> 0:28:44.040
<v Speaker 1>bloodshot eyes surrounded by deep character lines marking a lifetime

0:28:44.120 --> 0:28:47.800
<v Speaker 1>of squinting at water under the equatorial sun. He pulls

0:28:47.800 --> 0:28:50.360
<v Speaker 1>his black hair back in a well combed pony tail,

0:28:50.640 --> 0:28:53.800
<v Speaker 1>and often dons a baseball cap. The day we met,

0:28:54.080 --> 0:28:57.719
<v Speaker 1>he wore a football jersey emblazoned with Indonesia's national symbol,

0:28:58.080 --> 0:29:00.960
<v Speaker 1>the bird god Garuda. He walked me over to the

0:29:01.040 --> 0:29:04.280
<v Speaker 1>edge of the beach outside his pleated bamboo house. We

0:29:04.320 --> 0:29:06.960
<v Speaker 1>sat on a concrete bench that was partly wrecked and

0:29:07.040 --> 0:29:10.040
<v Speaker 1>partly buried in the sand. He pointed to a swing

0:29:10.120 --> 0:29:12.720
<v Speaker 1>about one hundred yards out in the water and said

0:29:12.720 --> 0:29:15.880
<v Speaker 1>it used to stand at the shoreline. As a child,

0:29:16.160 --> 0:29:19.440
<v Speaker 1>a reef traveled by sailboat to schools on neighboring islands.

0:29:19.880 --> 0:29:22.320
<v Speaker 1>In his third year of high school, his father fell

0:29:22.360 --> 0:29:26.920
<v Speaker 1>ill and was frequently hospitalized. Outside Jakarta, a reef dropped out.

0:29:27.320 --> 0:29:30.080
<v Speaker 1>When the Indonesian government set up a research station on

0:29:30.160 --> 0:29:33.200
<v Speaker 1>Pari Island. He joined the scientists on the water to

0:29:33.280 --> 0:29:36.640
<v Speaker 1>track fish and shrimp. I did research on coral and

0:29:36.680 --> 0:29:39.320
<v Speaker 1>could see the reefs were in good condition. He said

0:29:39.720 --> 0:29:44.080
<v Speaker 1>the coral supported marine life, including fish. When the government

0:29:44.160 --> 0:29:47.280
<v Speaker 1>transplanted a kind of seaweed from Bali that was valuable

0:29:47.320 --> 0:29:51.400
<v Speaker 1>to the cosmetics industry, areef became a seaweed and seagrass farmer.

0:29:51.920 --> 0:29:54.800
<v Speaker 1>It was, he said, with a smile, a vibrant business,

0:29:55.120 --> 0:29:57.760
<v Speaker 1>and the crops helped forge a strong local community of

0:29:57.800 --> 0:30:01.320
<v Speaker 1>sea farmers. When he described how the currents changed and

0:30:01.360 --> 0:30:04.360
<v Speaker 1>the coral died off, and the farmers tried and failed

0:30:04.360 --> 0:30:07.960
<v Speaker 1>to save their crops, his eyes welled up. He bowed

0:30:07.960 --> 0:30:10.840
<v Speaker 1>his head into his hands, wept, and spent a few

0:30:10.840 --> 0:30:15.160
<v Speaker 1>minutes gaining his composure. We don't have that community anymore,

0:30:15.440 --> 0:30:19.680
<v Speaker 1>he said. In twenty eighteen, then again in twenty twenty one,

0:30:20.120 --> 0:30:23.480
<v Speaker 1>Parie Island was hit by tidal floods so severe that

0:30:23.560 --> 0:30:27.320
<v Speaker 1>Aurife's home was overwhelmed by salt water. Sea rise and

0:30:27.440 --> 0:30:31.400
<v Speaker 1>rising ocean and atmospheric temperatures make tides more erratic and

0:30:31.480 --> 0:30:35.280
<v Speaker 1>floods more frequent and violent. When the water hit Aref's walls,

0:30:35.560 --> 0:30:40.040
<v Speaker 1>they collapsed. The house's rudimentary plumbing fell apart, too, leaving

0:30:40.080 --> 0:30:43.360
<v Speaker 1>the family with no toilet. His fresh water well, like

0:30:43.440 --> 0:30:47.160
<v Speaker 1>many on the island, was inundated and made unusable for weeks.

0:30:47.760 --> 0:30:51.280
<v Speaker 1>The salt water killed the chilies, tomatoes, papayas, and bananas

0:30:51.280 --> 0:30:53.920
<v Speaker 1>he grew on his land, and it overran the shop

0:30:53.960 --> 0:30:57.440
<v Speaker 1>where he sometimes worked as a mechanic. Over five years,

0:30:57.480 --> 0:31:00.880
<v Speaker 1>he said, the beach nearest his home lost nine meters

0:31:00.960 --> 0:31:04.960
<v Speaker 1>or thirty feet of land. When NGOs showed up to help,

0:31:05.240 --> 0:31:08.240
<v Speaker 1>they linked the rising waters and floods to climate change.

0:31:08.560 --> 0:31:11.240
<v Speaker 1>They asked for photos and videos, and a Reef showed

0:31:11.240 --> 0:31:14.200
<v Speaker 1>them many while he asked if the community wanted to

0:31:14.280 --> 0:31:16.720
<v Speaker 1>join a lawsuit, and that is how we started working

0:31:16.760 --> 0:31:20.400
<v Speaker 1>with HEX, he said from the NGO's point of view.

0:31:20.480 --> 0:31:24.280
<v Speaker 1>The Pari Island plaintiffs A Reef and Bobby, plus Asmania,

0:31:24.360 --> 0:31:29.480
<v Speaker 1>a shopkeeper, homestay operator, community organizer and mother, and Ed Mullono,

0:31:29.600 --> 0:31:32.040
<v Speaker 1>who works with and is an advocate for local fishermen,

0:31:32.520 --> 0:31:36.880
<v Speaker 1>have desirable profiles. They've gained little from industrial activity, but

0:31:37.000 --> 0:31:40.880
<v Speaker 1>nonetheless suffer from its consequences. Their minimal contact with the

0:31:40.920 --> 0:31:44.880
<v Speaker 1>carbon economy and their powerlessness against it gave them standing

0:31:44.920 --> 0:31:48.680
<v Speaker 1>to champion a global cause. I asked a Reef whether

0:31:48.760 --> 0:31:52.360
<v Speaker 1>Holsim's point forty two percent share of global carbon emissions

0:31:52.680 --> 0:31:55.880
<v Speaker 1>was really what made his blood boil. He acknowledged it

0:31:56.000 --> 0:31:59.680
<v Speaker 1>wasn't his top concern, but he said no one else

0:31:59.720 --> 0:32:02.360
<v Speaker 1>had come to help except for the Swiss, so we'd

0:32:02.440 --> 0:32:09.080
<v Speaker 1>joined them eight cold stops. In late August twenty twenty five,

0:32:09.440 --> 0:32:12.680
<v Speaker 1>a few days before their court hearing, Aarif and Asmania,

0:32:12.720 --> 0:32:15.760
<v Speaker 1>together with Pared and another while he official, were met

0:32:15.760 --> 0:32:19.080
<v Speaker 1>in Zurich by a team from hex Jetlag had hit

0:32:19.160 --> 0:32:22.200
<v Speaker 1>them hard, and they were ushered to their hotel to rest.

0:32:22.800 --> 0:32:25.800
<v Speaker 1>They'd anticipated that Swiss food would be too heavy and

0:32:25.840 --> 0:32:28.240
<v Speaker 1>bloating for them, so they set up a rice cooker

0:32:28.280 --> 0:32:30.560
<v Speaker 1>in one of the rooms. They had a week before

0:32:30.600 --> 0:32:34.160
<v Speaker 1>their procedural hearing Inzugue, but before then had a full

0:32:34.200 --> 0:32:37.960
<v Speaker 1>schedule of public campaigning. The next day, they stumbled half

0:32:38.000 --> 0:32:40.960
<v Speaker 1>awake into their first meeting, a strategy session at the

0:32:41.000 --> 0:32:45.040
<v Speaker 1>Heck's office. Even in summer, Switzerland felt cold to them,

0:32:45.440 --> 0:32:49.200
<v Speaker 1>as Mania bundled up in a fluffy blue fleece. One

0:32:49.280 --> 0:32:52.000
<v Speaker 1>of the first stops on the islander's publicity tour was

0:32:52.040 --> 0:32:55.720
<v Speaker 1>a snowy outlook at an ecologically threatened UNESCO World Heritage

0:32:55.800 --> 0:32:59.240
<v Speaker 1>site in the Bernese Alps above the Melting Alech Glacier

0:32:59.400 --> 0:33:03.800
<v Speaker 1>in Valais. Reporters and photographers from friendly press outlets followed

0:33:03.840 --> 0:33:07.080
<v Speaker 1>them up for the photoop. The site of frigid Islanders

0:33:07.080 --> 0:33:11.080
<v Speaker 1>who'd lost land drove home the complimentary challenge of landlocked

0:33:11.080 --> 0:33:14.520
<v Speaker 1>Swiss losing water. Later, the group traveled to a fish

0:33:14.520 --> 0:33:17.480
<v Speaker 1>house on a nearby lake and talked through a translator

0:33:17.680 --> 0:33:21.320
<v Speaker 1>to the fishermen there. Arf and Asmania joined the locals

0:33:21.320 --> 0:33:25.640
<v Speaker 1>detangling the day's catch from their nets. The house's gregarious owner,

0:33:25.800 --> 0:33:29.680
<v Speaker 1>who'd traveled to Bali, recited the names of some Indonesian dishes.

0:33:30.240 --> 0:33:33.680
<v Speaker 1>The visitors beamed at the welcome Although The stop was

0:33:33.680 --> 0:33:36.440
<v Speaker 1>meant to link climate change on Pari Island with that

0:33:36.560 --> 0:33:39.800
<v Speaker 1>in Switzerland. The happy host who owned this business said

0:33:39.800 --> 0:33:43.360
<v Speaker 1>the story is mixed. Some fish are disappearing from the waters,

0:33:43.720 --> 0:33:46.000
<v Speaker 1>but the warming of the lake has caused a population

0:33:46.120 --> 0:33:49.600
<v Speaker 1>boom in others that earn him more money. The Indonesians

0:33:49.640 --> 0:33:53.000
<v Speaker 1>had a wonderful time, but as propaganda for climate action,

0:33:53.360 --> 0:33:58.360
<v Speaker 1>the lake visit was a bust. Nine. The hard problem

0:33:58.720 --> 0:34:02.400
<v Speaker 1>the cement plants pumping carbon into the atmosphere vary widely

0:34:02.520 --> 0:34:06.200
<v Speaker 1>in size and output. Volumes from the biggest plants are

0:34:06.240 --> 0:34:10.560
<v Speaker 1>stackering and their production is unremitting. From its recently revamped

0:34:10.560 --> 0:34:14.160
<v Speaker 1>plant in Mitchell, Indiana, Heidelberg Materials can ship out one

0:34:14.239 --> 0:34:18.280
<v Speaker 1>thousand train cars filled with cement every day. The largest

0:34:18.360 --> 0:34:21.200
<v Speaker 1>US plant was built by Wholesome on the Mississippi River

0:34:21.360 --> 0:34:24.680
<v Speaker 1>in Bloomsdale, Missouri. It can now produce five point five

0:34:24.760 --> 0:34:28.000
<v Speaker 1>million tons a year, following a recent one hundred million

0:34:28.040 --> 0:34:32.040
<v Speaker 1>dollar expansion by its current owner, Amrise, which Wholesome spun

0:34:32.120 --> 0:34:34.680
<v Speaker 1>off in twenty twenty five to take over its US

0:34:34.719 --> 0:34:39.200
<v Speaker 1>and Canadian operations. Even before the expansion, the plant's cement

0:34:39.280 --> 0:34:42.560
<v Speaker 1>found its way into one in five US building projects.

0:34:43.440 --> 0:34:47.160
<v Speaker 1>The bigger plants are humblingly complex, looking like a jumble

0:34:47.200 --> 0:34:51.880
<v Speaker 1>of oil refineries, big city elevated train systems, domed sports arenas,

0:34:51.880 --> 0:34:55.279
<v Speaker 1>and mammoth silos. No matter the size or vintage of

0:34:55.280 --> 0:34:58.799
<v Speaker 1>the facility, though the basic chemistry is the same. Put

0:34:58.840 --> 0:35:01.040
<v Speaker 1>in lots of limestone, add a bit of clay and

0:35:01.120 --> 0:35:05.600
<v Speaker 1>gypsum get cement out. Many of the plants, including amorses,

0:35:05.800 --> 0:35:09.560
<v Speaker 1>are situated next to thick bedded limestone deposits to feed

0:35:09.600 --> 0:35:12.680
<v Speaker 1>the cement kilns. Limestone chunks are blasted out of the

0:35:12.760 --> 0:35:16.600
<v Speaker 1>quarry and excavated by huge diggers. The stone is dumped

0:35:16.600 --> 0:35:20.160
<v Speaker 1>into a powerful crusher that reduces the big pieces to chunks,

0:35:20.440 --> 0:35:23.040
<v Speaker 1>which are then fed into a grinder that further reduces

0:35:23.080 --> 0:35:26.400
<v Speaker 1>the stone to a finely powdered product called raw meal.

0:35:27.120 --> 0:35:30.040
<v Speaker 1>That powder, mixed with some clay, is conveyed to the

0:35:30.040 --> 0:35:33.239
<v Speaker 1>top of a steel preheater tower, where it travels through

0:35:33.280 --> 0:35:36.160
<v Speaker 1>several stages designed to drive most of the co two

0:35:36.320 --> 0:35:39.240
<v Speaker 1>out of the rock. Most of this happens by spinning

0:35:39.280 --> 0:35:42.120
<v Speaker 1>the stone and clay in a super hot cyclone that

0:35:42.480 --> 0:35:45.080
<v Speaker 1>cooks it in stages until it goes inside a furnace

0:35:45.120 --> 0:35:48.760
<v Speaker 1>called a calciner. The stone's temperature reaches about eighteen hundred

0:35:48.760 --> 0:35:53.800
<v Speaker 1>degrees fahrenheit, hot enough to release carbon dioxide unless captured,

0:35:53.880 --> 0:35:56.720
<v Speaker 1>the gas heads into the air. This is the process

0:35:56.760 --> 0:36:00.520
<v Speaker 1>that makes cement production so destructive to the environment. The

0:36:00.560 --> 0:36:05.240
<v Speaker 1>remaining solid calcium oxide, also known as quicklime, then travels

0:36:05.280 --> 0:36:09.319
<v Speaker 1>again to a giant tubular rotary kiln amorrhizes is three

0:36:09.360 --> 0:36:12.600
<v Speaker 1>hundred feet long that produces heat as high as twenty

0:36:12.640 --> 0:36:16.840
<v Speaker 1>seven hundred degrees fahrenheit. In time, small gray pellets of

0:36:16.840 --> 0:36:20.840
<v Speaker 1>a new material emerge. This is clinker, the ingredient that

0:36:20.880 --> 0:36:24.800
<v Speaker 1>makes Portland cement reactive. When the clinker is finely ground

0:36:24.800 --> 0:36:29.040
<v Speaker 1>and mixed with gypsum, the Portland cement is finished. Remember

0:36:29.160 --> 0:36:31.600
<v Speaker 1>that ten percent to fifteen per cent of a traditional

0:36:31.640 --> 0:36:35.240
<v Speaker 1>batch of concrete is made up of clinker based Portland cement.

0:36:35.800 --> 0:36:39.920
<v Speaker 1>Because its fabrication process leads to such prolific emissions, industry

0:36:39.960 --> 0:36:43.439
<v Speaker 1>decarbonization efforts most often focus on ways to use less

0:36:43.440 --> 0:36:47.319
<v Speaker 1>clinker in cement and less Portland cement in concrete. The

0:36:47.360 --> 0:36:52.120
<v Speaker 1>shorthand for this is lowering the clinker factor. To environmentalists

0:36:52.160 --> 0:36:56.440
<v Speaker 1>and corporate sustainability chiefs. Decarbonising cement is often called the

0:36:56.560 --> 0:37:01.200
<v Speaker 1>hard problem. There are three particular reasons. For one, there's

0:37:01.280 --> 0:37:04.160
<v Speaker 1>the roughly forty percent of the industry's CO two that

0:37:04.320 --> 0:37:07.719
<v Speaker 1>comes from burning fuel, usually coal, with some mix of

0:37:07.760 --> 0:37:12.640
<v Speaker 1>industrial waste to sustain requisite high temperatures. Efficient furnaces and

0:37:12.719 --> 0:37:16.239
<v Speaker 1>recycled fuels can reduce emissions, but the industry needs new

0:37:16.280 --> 0:37:20.319
<v Speaker 1>supply chains to provide alternative fuels. A second challenge is

0:37:20.360 --> 0:37:23.279
<v Speaker 1>that other sixty percent of emissions the result of the

0:37:23.360 --> 0:37:27.760
<v Speaker 1>chemical transformation of the stone. Although the intense energy required

0:37:27.800 --> 0:37:32.040
<v Speaker 1>to cook cement doesn't rely on electricity, the world's cement plants,

0:37:32.080 --> 0:37:36.160
<v Speaker 1>with their huge everturning crushers, grinders, conveyors, and other equipment,

0:37:36.600 --> 0:37:39.280
<v Speaker 1>drive as much as one point five percent of global

0:37:39.320 --> 0:37:44.520
<v Speaker 1>electricity demand. Electricity, however, isn't considered part of cement's hard

0:37:44.560 --> 0:37:49.000
<v Speaker 1>problem because renewable power sources can eventually meet the industry's needs.

0:37:49.600 --> 0:37:52.359
<v Speaker 1>The third challenge is the vast amount of cement the

0:37:52.400 --> 0:37:56.160
<v Speaker 1>world uses. The production of concrete made with Portland cement

0:37:56.480 --> 0:37:59.520
<v Speaker 1>emits far less CO two for any given volume than

0:37:59.520 --> 0:38:03.680
<v Speaker 1>the production of other major building materials, making steel amits

0:38:03.800 --> 0:38:07.640
<v Speaker 1>thirty eight times more and glass six times more producing

0:38:07.680 --> 0:38:11.399
<v Speaker 1>timber for construction. Yes, timber can in the near term

0:38:11.520 --> 0:38:15.120
<v Speaker 1>also emit more CO two than cement and concrete, especially

0:38:15.160 --> 0:38:18.760
<v Speaker 1>if the wood originates from clear cut forests. The decaying

0:38:18.800 --> 0:38:22.719
<v Speaker 1>material in clear cut boreal forests makes them net emitters

0:38:22.719 --> 0:38:25.640
<v Speaker 1>of greenhouse gases for as long as twenty five years

0:38:25.920 --> 0:38:30.600
<v Speaker 1>before new growth makes the forests net absorbers. In another paradox,

0:38:30.920 --> 0:38:34.759
<v Speaker 1>cement is so widely used because it's so benign. If

0:38:34.800 --> 0:38:38.160
<v Speaker 1>the world consumed equally high volumes of steel, the most

0:38:38.239 --> 0:38:42.120
<v Speaker 1>nightmarish climate change scenarios might already be in full swing.

0:38:43.280 --> 0:38:49.640
<v Speaker 1>We'll be right back with curing concrete. Welcome back to

0:38:50.239 --> 0:38:56.480
<v Speaker 1>curing concrete. Ten it's not a cement truck. One way

0:38:56.520 --> 0:38:59.200
<v Speaker 1>to really rankle someone in the cement business or the

0:38:59.239 --> 0:39:03.240
<v Speaker 1>concrete business is to confuse the two materials. Both trades

0:39:03.280 --> 0:39:06.319
<v Speaker 1>people and executives have reminded me at nauseum that most

0:39:06.400 --> 0:39:10.239
<v Speaker 1>people don't know the difference. Again, cement is a constituent

0:39:10.280 --> 0:39:14.040
<v Speaker 1>of concrete. Concrete is what we build with. About eighty

0:39:14.080 --> 0:39:16.680
<v Speaker 1>percent of the concrete business in the US is in

0:39:16.719 --> 0:39:20.160
<v Speaker 1>what the industry calls ready mix, the poorable variety that

0:39:20.200 --> 0:39:24.080
<v Speaker 1>travels wet and is shaped and finished at the job. Globally,

0:39:24.120 --> 0:39:27.360
<v Speaker 1>about half of all concrete is ready mix. It's usually

0:39:27.360 --> 0:39:31.279
<v Speaker 1>produced in compact industrial yards called batch plants, some of

0:39:31.280 --> 0:39:34.240
<v Speaker 1>which cover several acres and others of which are squeezed

0:39:34.280 --> 0:39:38.239
<v Speaker 1>into city blocks. Batch plants are more like depots than factories.

0:39:38.520 --> 0:39:41.760
<v Speaker 1>They have rows of bins to store raw materials cement,

0:39:42.040 --> 0:39:46.200
<v Speaker 1>sand stone, chemicals and coloring and dispense them into concrete

0:39:46.239 --> 0:39:50.080
<v Speaker 1>mixer trucks, the one with the big rotating barrels. The

0:39:50.120 --> 0:39:53.839
<v Speaker 1>mix comes together with water or sometimes liquid carbon dioxide

0:39:54.080 --> 0:39:57.080
<v Speaker 1>and begins to cure and harden inside the truck's barrels

0:39:57.080 --> 0:40:01.080
<v Speaker 1>as they travel to their destinations. Rary to popular belief,

0:40:01.400 --> 0:40:05.080
<v Speaker 1>concrete doesn't harden because it dries. It hardens because the

0:40:05.080 --> 0:40:09.080
<v Speaker 1>elements are pulled together by the chemistry of hydration. Concrete

0:40:09.280 --> 0:40:13.800
<v Speaker 1>dries because hydration hardens it. In fact, it will continue

0:40:13.800 --> 0:40:17.560
<v Speaker 1>to gain strength for decades as unreacted cement particles within

0:40:17.600 --> 0:40:21.240
<v Speaker 1>the mass continue to slowly hydrate whenever they meet moisture.

0:40:21.880 --> 0:40:25.480
<v Speaker 1>In addition, unfinished concrete, when left open to the elements,

0:40:25.719 --> 0:40:29.279
<v Speaker 1>slowly absorbs carbon dioxide from the atmosphere, which makes the

0:40:29.320 --> 0:40:33.080
<v Speaker 1>material a bit harder. Still, some concrete, like that used

0:40:33.120 --> 0:40:36.040
<v Speaker 1>by ancient Romans to build the Pantheon to millennia ago,

0:40:36.520 --> 0:40:39.839
<v Speaker 1>actually heals its own cracks and can continue to grow

0:40:39.920 --> 0:40:44.080
<v Speaker 1>harder over centuries on its way to becoming rock hard.

0:40:44.280 --> 0:40:47.920
<v Speaker 1>Concrete is highly perishable. It takes about ninety minutes of

0:40:47.960 --> 0:40:51.040
<v Speaker 1>turning in a truck before hydration goes too far and

0:40:51.160 --> 0:40:55.000
<v Speaker 1>concrete becomes too stiff to mold, smooth, or push into place.

0:40:55.560 --> 0:40:59.919
<v Speaker 1>That makes production highly local. In busy cities, dispatch center

0:41:00.160 --> 0:41:03.600
<v Speaker 1>look like air traffic control rooms as forty ton trucks

0:41:03.640 --> 0:41:06.799
<v Speaker 1>are timed and steered through packed streets and around road

0:41:06.840 --> 0:41:10.520
<v Speaker 1>construction and bridges unfit to carry their weight. There are

0:41:10.600 --> 0:41:14.239
<v Speaker 1>seven thousand ready mixed batch plants in the US by

0:41:14.320 --> 0:41:17.800
<v Speaker 1>rough estimate. There are at least one hundred thousand worldwide.

0:41:18.320 --> 0:41:21.680
<v Speaker 1>That's fifteen percent more than all branches of McDonald's and

0:41:21.760 --> 0:41:26.800
<v Speaker 1>Starbucks combined. Half of the world's concrete, though, isn't delivered

0:41:26.800 --> 0:41:29.960
<v Speaker 1>by mixer trucks. It's made from bags of cement that

0:41:30.000 --> 0:41:33.600
<v Speaker 1>are combined with other ingredients on site. The world purchases

0:41:33.640 --> 0:41:36.560
<v Speaker 1>the equivalent of thirty six billion, one hundred and ten

0:41:36.640 --> 0:41:40.319
<v Speaker 1>pound bags of cement annually. Much of that heads into

0:41:40.360 --> 0:41:45.839
<v Speaker 1>small projects in emerging economies, including family home construction. The favellas,

0:41:45.920 --> 0:41:49.560
<v Speaker 1>barrios and shantytowns that hug the developing worlds. Burgeoning big

0:41:49.640 --> 0:41:52.919
<v Speaker 1>cities are filled with makeshift homes that are slowly being

0:41:53.000 --> 0:41:57.360
<v Speaker 1>concretized by their owners. In twenty twenty four, I traveled

0:41:57.360 --> 0:42:01.000
<v Speaker 1>to Metazine, Columbia, to investigate the benefit of replacing dirt

0:42:01.040 --> 0:42:05.560
<v Speaker 1>floors with concrete in the city's poorest neighborhoods. As in Mexico,

0:42:05.760 --> 0:42:10.080
<v Speaker 1>the change was transformative. Cement for ten thousand floors, as

0:42:10.080 --> 0:42:12.279
<v Speaker 1>well as some of the stone and sand needed to

0:42:12.320 --> 0:42:16.600
<v Speaker 1>make concrete, had been donated by Cementos Argos, the country's

0:42:16.600 --> 0:42:20.759
<v Speaker 1>biggest cement producer. While there, I visited Argos's open air

0:42:20.800 --> 0:42:24.399
<v Speaker 1>warehouse for bagged cement. The sacks filled a floor about

0:42:24.400 --> 0:42:27.480
<v Speaker 1>a quarter mile long and three hundred yards wide. The

0:42:27.520 --> 0:42:30.640
<v Speaker 1>warehouse contained a total of about one hundred thousand bags,

0:42:31.040 --> 0:42:33.239
<v Speaker 1>which I was told would all be moved out and

0:42:33.280 --> 0:42:37.080
<v Speaker 1>replenished over the course of three days. The numbers seemed

0:42:37.120 --> 0:42:40.600
<v Speaker 1>inconceivable until I climbed the many miles of new concrete

0:42:40.640 --> 0:42:43.440
<v Speaker 1>stairs in one of the ever expanding slum zones that

0:42:43.520 --> 0:42:46.719
<v Speaker 1>snake up the hillsides on the city's edge. Cars and

0:42:46.760 --> 0:42:50.560
<v Speaker 1>motorbikes can't manage the steep inclines, so the residents joined

0:42:50.600 --> 0:42:54.320
<v Speaker 1>together to build steps connecting their neighborhood internally and to others.

0:42:54.880 --> 0:42:58.520
<v Speaker 1>In addition to making the hillsides habitable, this construction allows

0:42:58.520 --> 0:43:00.560
<v Speaker 1>the people to carry bags of a sa meant up

0:43:00.600 --> 0:43:04.560
<v Speaker 1>to the homes their building or reinforcing argos. Sacks lean

0:43:04.640 --> 0:43:07.919
<v Speaker 1>against half finished houses. One man told me he'd bought

0:43:07.960 --> 0:43:10.640
<v Speaker 1>the bag I saw near his home five years earlier

0:43:10.880 --> 0:43:13.480
<v Speaker 1>and had been building with it since. He said it

0:43:13.520 --> 0:43:15.560
<v Speaker 1>took him so long because he can afford to make

0:43:15.600 --> 0:43:18.680
<v Speaker 1>concrete only with the stones that collect in his wife's

0:43:18.719 --> 0:43:22.520
<v Speaker 1>bucket while she does laundry in a nearby creek. Workers

0:43:22.560 --> 0:43:25.200
<v Speaker 1>in the crews of construction companies building in the more

0:43:25.239 --> 0:43:29.239
<v Speaker 1>prosperous central zones of Metagine often hail from the informal

0:43:29.239 --> 0:43:32.399
<v Speaker 1>communities at the edges of the city. Skills learned at

0:43:32.400 --> 0:43:35.359
<v Speaker 1>work migrate back to their home building projects or those

0:43:35.400 --> 0:43:38.240
<v Speaker 1>of their neighbors. There are roughly two hundred and eighty

0:43:38.360 --> 0:43:42.040
<v Speaker 1>million construction workers in the world, and almost all construction

0:43:42.160 --> 0:43:47.000
<v Speaker 1>involves concrete. The International Finance Corporation estimates that cement and

0:43:47.080 --> 0:43:51.000
<v Speaker 1>concrete's long and diverse supply chain makes up five point

0:43:51.040 --> 0:43:53.920
<v Speaker 1>four percent of all the world's goods and services and

0:43:54.000 --> 0:44:01.840
<v Speaker 1>employs about one in thirteen workers eleven zero progress. Among

0:44:01.920 --> 0:44:06.320
<v Speaker 1>the top ten cement producers, Wholsim, together with Heidelberg Materials,

0:44:06.600 --> 0:44:10.560
<v Speaker 1>has the most comprehensive approach to decarbonizing its business. The

0:44:10.600 --> 0:44:14.680
<v Speaker 1>company nevertheless remains a top historical CO two emitter across

0:44:14.719 --> 0:44:18.799
<v Speaker 1>all industries. It's among the so called carbon Majors one

0:44:18.840 --> 0:44:21.960
<v Speaker 1>hundred twenty two companies that since the mid nineteenth century

0:44:22.239 --> 0:44:26.000
<v Speaker 1>have produced about eighty eight percent of industrial carbon emissions.

0:44:26.719 --> 0:44:30.640
<v Speaker 1>Carbon Majors, an organization that tracks top greenhouse gas emitters,

0:44:30.880 --> 0:44:35.719
<v Speaker 1>ranks Wholseam seventy seventh. Historically, fossil fuel producers dominate the

0:44:35.760 --> 0:44:39.440
<v Speaker 1>top of the list. Wholsim's recent record is better. For

0:44:39.520 --> 0:44:42.240
<v Speaker 1>the year twenty twenty four, the company was one hundred

0:44:42.239 --> 0:44:45.640
<v Speaker 1>and twenty sixth on the Carbon Major's list. Its emissions

0:44:45.640 --> 0:44:48.840
<v Speaker 1>have been dropping, in part because of the ongoing decarbonization

0:44:48.960 --> 0:44:51.759
<v Speaker 1>of its cement production, but in larger part because of

0:44:51.800 --> 0:44:55.239
<v Speaker 1>its spinoff of its North American operations and Amrise and

0:44:55.320 --> 0:44:58.120
<v Speaker 1>its sale of big subsidiaries in Brazil and Egypt for

0:44:58.200 --> 0:45:02.040
<v Speaker 1>seven point three billion dollars. Should one be cynical about

0:45:02.040 --> 0:45:06.520
<v Speaker 1>carbon reductions that result mostly from corporate restructuring rather than

0:45:06.520 --> 0:45:10.440
<v Speaker 1>from actual changes within high emitting divisions. That depends on

0:45:10.480 --> 0:45:14.080
<v Speaker 1>how a company applies the proceeds of the restructuring. Wholesome

0:45:14.280 --> 0:45:17.000
<v Speaker 1>used three point four billion dollars from the sales to

0:45:17.040 --> 0:45:21.399
<v Speaker 1>diversify into roofing the lower carbon industry. It used two

0:45:21.400 --> 0:45:24.320
<v Speaker 1>billion dollars to buy back shares, which has no effect

0:45:24.400 --> 0:45:28.120
<v Speaker 1>on emissions. In many ways. The cement industry has been

0:45:28.160 --> 0:45:31.560
<v Speaker 1>on trial for its carbon emissions since the mid nineteen nineties.

0:45:31.960 --> 0:45:35.520
<v Speaker 1>In nineteen ninety seven, the Kyoto Protocol committed developed nations

0:45:35.520 --> 0:45:40.200
<v Speaker 1>to significant cuts in greenhouse emissions. Around that time, European

0:45:40.239 --> 0:45:43.760
<v Speaker 1>countries were beginning to draft carbon tax laws and carbon

0:45:43.840 --> 0:45:47.000
<v Speaker 1>trading systems, some of which are now in place. The

0:45:47.000 --> 0:45:51.920
<v Speaker 1>twenty fifteen Paris Climate Agreement pushed governments, global institutional investors,

0:45:51.960 --> 0:45:55.759
<v Speaker 1>and big companies to commit to lower carbon emissions. Some

0:45:55.840 --> 0:45:59.120
<v Speaker 1>corporations began to regard climate risks as threats to their

0:45:59.120 --> 0:46:03.279
<v Speaker 1>bottom line. Cement and concrete producers, though, were slow to

0:46:03.320 --> 0:46:07.319
<v Speaker 1>act through the early two thousands. Jezus Subero, formerly head

0:46:07.360 --> 0:46:10.319
<v Speaker 1>of cement research and development at Wholsom, told me all

0:46:10.400 --> 0:46:14.120
<v Speaker 1>the cement majors wanted to ramp up capacity. Innovation was

0:46:14.160 --> 0:46:18.320
<v Speaker 1>not that important. People wanted cement to help concrete, set, harden,

0:46:18.600 --> 0:46:22.279
<v Speaker 1>provide compressive strength, and to never collapse. Cement was seen

0:46:22.280 --> 0:46:26.480
<v Speaker 1>as a commodity for decades. Repeatedly, people in the industry

0:46:26.520 --> 0:46:29.080
<v Speaker 1>told me their product was already making the world better

0:46:29.160 --> 0:46:32.719
<v Speaker 1>in innumerable ways. Building the world we have was a

0:46:32.800 --> 0:46:35.719
<v Speaker 1>huge point of pride for them. Casting their industry as

0:46:35.760 --> 0:46:41.040
<v Speaker 1>a planetary destroyer didn't compute. Eventually, the cement industry assembled

0:46:41.080 --> 0:46:45.239
<v Speaker 1>working groups and initiatives studying sustainability. In twenty twenty one,

0:46:45.440 --> 0:46:49.319
<v Speaker 1>the Global Cement and Concrete Association, an organization created and

0:46:49.360 --> 0:46:53.000
<v Speaker 1>funded by the world's leading cement producers, committed its members

0:46:53.000 --> 0:46:57.080
<v Speaker 1>to being net zero, not emitting any carbon by twenty fifty.

0:46:57.680 --> 0:47:00.160
<v Speaker 1>This made cement the first heavy industry to me make

0:47:00.200 --> 0:47:04.280
<v Speaker 1>a big climate commitment. The largest companies refitted old plants

0:47:04.280 --> 0:47:07.880
<v Speaker 1>to burn fossil fuels such as coal more efficiently and

0:47:08.040 --> 0:47:12.120
<v Speaker 1>use alternative fuels such as used tires and biomass. These

0:47:12.160 --> 0:47:15.200
<v Speaker 1>measures lowered both their costs and the emissions per ton

0:47:15.239 --> 0:47:18.160
<v Speaker 1>of cement, and gave them a claim to some climate action.

0:47:19.280 --> 0:47:22.960
<v Speaker 1>Wholesome calculated that from nineteen ninety to twenty twenty, even

0:47:23.040 --> 0:47:26.600
<v Speaker 1>before the GCCA pledge, it had slashed the CO two

0:47:26.640 --> 0:47:29.160
<v Speaker 1>emitted for every ton of cement by twenty eight percent.

0:47:29.880 --> 0:47:32.160
<v Speaker 1>Much of that reduction was the result of changes in

0:47:32.200 --> 0:47:35.120
<v Speaker 1>its energy diet, Though the carbon accounting used by the

0:47:35.120 --> 0:47:39.400
<v Speaker 1>cement industry is controversial. One issue is whether burning tires

0:47:39.440 --> 0:47:42.799
<v Speaker 1>as fuel is a low carbon strategy. Wholesome and the

0:47:42.800 --> 0:47:44.719
<v Speaker 1>rest of the industry make the case that it is

0:47:45.120 --> 0:47:48.360
<v Speaker 1>because it avoids the decomposition of the tires in landfills,

0:47:48.640 --> 0:47:51.400
<v Speaker 1>where they give off methane and even more potent greenhouse

0:47:51.440 --> 0:47:55.520
<v Speaker 1>gas than carbon dioxide. In any case, the sector's overall

0:47:55.600 --> 0:47:59.280
<v Speaker 1>carbon footprint didn't shrink. It was reaching all time highs

0:47:59.280 --> 0:48:03.680
<v Speaker 1>because the appetite for cement and concrete grew. Concrete producers

0:48:03.719 --> 0:48:06.680
<v Speaker 1>don't need to stick with their customary amounts of Portland

0:48:06.760 --> 0:48:10.240
<v Speaker 1>cement if other formulas reduce the use of Portland cement

0:48:10.320 --> 0:48:13.160
<v Speaker 1>or even eliminate it, but function as well or better

0:48:13.200 --> 0:48:16.640
<v Speaker 1>at a competitive price. The hard problem can be cracked,

0:48:17.239 --> 0:48:20.000
<v Speaker 1>but makers and users of cement and concrete have a

0:48:20.040 --> 0:48:24.400
<v Speaker 1>strong conservative streak. Concrete formulas that rely heavily on Portland

0:48:24.440 --> 0:48:26.879
<v Speaker 1>cement have track records that reach back more than one

0:48:26.920 --> 0:48:31.359
<v Speaker 1>hundred years. Their use is one of modernity's great natural experiments.

0:48:31.719 --> 0:48:34.399
<v Speaker 1>It's tough to simulate in a model or lab one

0:48:34.440 --> 0:48:37.239
<v Speaker 1>hundred years of stress in environmental wear and tear on

0:48:37.320 --> 0:48:42.000
<v Speaker 1>structures made with new, radically innovative materials, but Scotland's glenfen

0:48:42.080 --> 0:48:45.200
<v Speaker 1>And Viaduct from nineteen oh one, famous as the Harry

0:48:45.239 --> 0:48:49.080
<v Speaker 1>Potter Bridge, the locks of the Panama Canal nineteen fifteen

0:48:49.480 --> 0:48:52.920
<v Speaker 1>and the Hoover Dam nineteen thirty six attest to the

0:48:53.000 --> 0:48:57.440
<v Speaker 1>durability of the Portland cement concrete combo. Save for devastation

0:48:57.600 --> 0:49:01.680
<v Speaker 1>prompted by wars and natural disasters, structural failure of concrete

0:49:01.680 --> 0:49:05.879
<v Speaker 1>buildings built to code is statistically rare. New materials must

0:49:05.880 --> 0:49:10.800
<v Speaker 1>prove themselves against this record. Among heavy carbon emitting industries,

0:49:11.040 --> 0:49:14.320
<v Speaker 1>the decarbonization of the cement and concrete sector has fared

0:49:14.360 --> 0:49:17.360
<v Speaker 1>somewhere in the middle. It's been far better at reducing

0:49:17.400 --> 0:49:20.719
<v Speaker 1>its per volume emissions than the fossil fuel industry, but

0:49:20.880 --> 0:49:23.760
<v Speaker 1>notably worse than the power sector, which has been rapidly

0:49:23.800 --> 0:49:28.480
<v Speaker 1>transitioning to renewable sources. Wholesome and Heidelberg Materials have committed

0:49:28.560 --> 0:49:31.319
<v Speaker 1>hundreds of millions of dollars to further driving down their

0:49:31.320 --> 0:49:35.000
<v Speaker 1>emissions with a new generation of carbon capture systems that

0:49:35.080 --> 0:49:38.200
<v Speaker 1>snare carbon from cement plants before it's release into the air.

0:49:38.760 --> 0:49:42.040
<v Speaker 1>Billions in subsidies to the companies from the European Union

0:49:42.120 --> 0:49:45.800
<v Speaker 1>and European national governments and from Canada help foot the bill.

0:49:46.400 --> 0:49:50.080
<v Speaker 1>In June twenty twenty five, Heidelberg Materials open the cement

0:49:50.160 --> 0:49:54.440
<v Speaker 1>industry's first industrial scale carbon capture plant, is attached to

0:49:54.480 --> 0:49:56.520
<v Speaker 1>one of two production lines at a one hundred year

0:49:56.520 --> 0:50:00.239
<v Speaker 1>old cement works in Brevik, Norway. Still considered a pilot,

0:50:00.480 --> 0:50:03.560
<v Speaker 1>the system will capture four hundred thousand tons of carbon

0:50:03.600 --> 0:50:07.200
<v Speaker 1>dioxide a year. The gas will be liquefied and transported

0:50:07.239 --> 0:50:10.360
<v Speaker 1>to the North Sea, where the project's backers say it

0:50:10.400 --> 0:50:14.440
<v Speaker 1>will be permanently stored beneath the seabed. The Norwegian government

0:50:14.480 --> 0:50:16.840
<v Speaker 1>paid close to eighty percent of the plant's four hundred

0:50:16.840 --> 0:50:20.479
<v Speaker 1>and forty million dollar cost. Wholesome pledges to have eight

0:50:20.640 --> 0:50:25.000
<v Speaker 1>new carbon capture plants, also heavily subsidized, live in Europe

0:50:25.040 --> 0:50:28.960
<v Speaker 1>by twenty thirty. With half a megaton captured here and

0:50:29.000 --> 0:50:32.840
<v Speaker 1>a megaton captured there, carbon capture can't yet promise carbon

0:50:32.880 --> 0:50:35.719
<v Speaker 1>reductions close to the scale of the cement industry's one

0:50:35.800 --> 0:50:40.000
<v Speaker 1>point six gigatons of yearly emissions. A gigaton is one

0:50:40.040 --> 0:50:45.160
<v Speaker 1>thousand megatons, and carbon capture still needs huge subsidies, which

0:50:45.200 --> 0:50:49.279
<v Speaker 1>makes the technology vulnerable to fickle politics. Last year, the

0:50:49.360 --> 0:50:51.680
<v Speaker 1>US Department of Energy pulled the plug on a five

0:50:51.760 --> 0:50:55.239
<v Speaker 1>hundred million dollar grant Joe Biden's administration had signaled it

0:50:55.239 --> 0:50:58.759
<v Speaker 1>would fund for carbon capture at Heidelberg cement plant in Indiana.

0:50:59.360 --> 0:51:03.000
<v Speaker 1>In November, the Swedish Energy Agency refused to commit eight

0:51:03.080 --> 0:51:06.799
<v Speaker 1>hundred and seventy million dollars to a long planned project. Then,

0:51:06.960 --> 0:51:09.719
<v Speaker 1>in late May, in a move giving carbon capture an

0:51:09.840 --> 0:51:13.120
<v Speaker 1>enormous boost, the government of Denmark, together with the EU,

0:51:13.520 --> 0:51:16.480
<v Speaker 1>committed more than four billion dollars for a carbon capture

0:51:16.520 --> 0:51:20.680
<v Speaker 1>system for the company Aalborg Portland Holding. One selling point

0:51:20.719 --> 0:51:23.560
<v Speaker 1>for the big outlay was that given the country's commitment

0:51:23.640 --> 0:51:26.799
<v Speaker 1>under the twenty twenty Danish Climate Act to drive down

0:51:26.840 --> 0:51:30.680
<v Speaker 1>carbon emissions. Generally, it could keep its domestic cement production

0:51:30.960 --> 0:51:34.520
<v Speaker 1>only by building the system. Otherwise Denmark would end up

0:51:34.560 --> 0:51:38.760
<v Speaker 1>importing cement and in effect exporting its emissions. The cement

0:51:38.800 --> 0:51:42.080
<v Speaker 1>plant is both the country's biggest industrial emitter and a

0:51:42.080 --> 0:51:45.880
<v Speaker 1>crucial supplier to its industrial base. It's hard to predict

0:51:45.920 --> 0:51:49.440
<v Speaker 1>where support or opposition to climate action will come from.

0:51:49.719 --> 0:51:53.080
<v Speaker 1>In Denmark's support came from conservative industrial quarters and from

0:51:53.200 --> 0:51:57.360
<v Speaker 1>labor unions. The cement industry generally takes a progressive stance

0:51:57.400 --> 0:52:01.120
<v Speaker 1>on climate when it can benefit. During the Biden administration,

0:52:01.280 --> 0:52:04.319
<v Speaker 1>when incentives for sustainable construction were added to the one

0:52:04.320 --> 0:52:08.560
<v Speaker 1>point two trillion dollar Infrastructure Investment and Jobs Act, Wholesome,

0:52:08.840 --> 0:52:11.640
<v Speaker 1>then still active in the US, had its lobbyist push

0:52:11.760 --> 0:52:15.440
<v Speaker 1>hard for eleven provisions that gave government projects incentives to

0:52:15.600 --> 0:52:21.760
<v Speaker 1>use lower carbon materials. They all passed twelve waste knocked.

0:52:22.840 --> 0:52:27.040
<v Speaker 1>In twenty fifteen, Wholesome merged with the French cement giant LeFarge,

0:52:27.360 --> 0:52:30.920
<v Speaker 1>creating what was then the world's largest cement company outside China.

0:52:31.480 --> 0:52:35.440
<v Speaker 1>LaFarge's research center southeast of Lyone and San Quentin, Fallavier

0:52:35.840 --> 0:52:39.680
<v Speaker 1>came with the deal. It's a standing argument against concrete's

0:52:39.719 --> 0:52:44.680
<v Speaker 1>stigma for ugliness. Renzo Piano, the superstar Genoese architect famed

0:52:44.680 --> 0:52:48.759
<v Speaker 1>for buildings that maximize natural light, feel transparent, and use

0:52:48.880 --> 0:52:53.600
<v Speaker 1>materials sparingly designed the complex. He imbued all those qualities

0:52:53.640 --> 0:52:56.680
<v Speaker 1>in low lying white buildings set on a verdant site

0:52:56.719 --> 0:53:00.480
<v Speaker 1>near an ancient Roman road and recently amazon on France

0:53:00.560 --> 0:53:05.640
<v Speaker 1>logistique warehouses. The complex's primary hall, opened in nineteen ninety four,

0:53:05.960 --> 0:53:09.520
<v Speaker 1>has been redesigned in biophilic green and blue as an

0:53:09.520 --> 0:53:13.359
<v Speaker 1>exhibit of concrete's low carbon future. Behind the front hall

0:53:13.400 --> 0:53:16.719
<v Speaker 1>are the lab buildings where innovations are developed and tested.

0:53:17.320 --> 0:53:20.719
<v Speaker 1>The twenty twenty three reinvention of the complex, now called

0:53:20.760 --> 0:53:24.960
<v Speaker 1>the Wholesome Innovation Hub, was spearheaded by Idelio Burmejo, a

0:53:25.000 --> 0:53:28.360
<v Speaker 1>sturdy French Spanish material scientist with a full head of

0:53:28.400 --> 0:53:32.200
<v Speaker 1>white hair and sapphire eyes. Burmejo has a twenty five

0:53:32.280 --> 0:53:35.600
<v Speaker 1>year history weighing and witnessing the promise and hype of

0:53:35.719 --> 0:53:40.400
<v Speaker 1>hundreds of cement and concrete innovations. Almost every day, startups

0:53:40.400 --> 0:53:43.560
<v Speaker 1>and academic labs announce research results that claim to offer

0:53:43.640 --> 0:53:47.920
<v Speaker 1>materials that are stronger, cleaner, and faster curing. Some materials

0:53:47.920 --> 0:53:50.880
<v Speaker 1>are designed to slot seamlessly into the well established ways

0:53:50.920 --> 0:53:55.000
<v Speaker 1>people use concrete today. Others aim to accelerate more radical

0:53:55.080 --> 0:53:58.160
<v Speaker 1>changes in construction, such as the use of robots that

0:53:58.280 --> 0:54:02.280
<v Speaker 1>leverage digital technology to lower the construction sector's carbon footprint.

0:54:02.800 --> 0:54:06.640
<v Speaker 1>Burmeho's labs vet them, they choose which ones wholesome will

0:54:06.640 --> 0:54:10.239
<v Speaker 1>explore and through the company's venture capital arm invest in.

0:54:11.040 --> 0:54:13.520
<v Speaker 1>When I met Burmeho in early March for a tour,

0:54:13.840 --> 0:54:16.640
<v Speaker 1>he pointed to a small, arched bridge with spans that

0:54:16.719 --> 0:54:20.800
<v Speaker 1>stretched like a rigid cephalopod in four directions. The bridge

0:54:20.840 --> 0:54:24.280
<v Speaker 1>was built with modular concrete blocks that were three D printed.

0:54:25.000 --> 0:54:28.160
<v Speaker 1>They can be dismantled then reconfigured in a new location.

0:54:28.719 --> 0:54:32.160
<v Speaker 1>The most sustainable strategy with materials, after all, isn't to

0:54:32.200 --> 0:54:35.360
<v Speaker 1>make any more at all, but to reuse them. The

0:54:35.400 --> 0:54:38.040
<v Speaker 1>bridge was also built to demonstrate one of Wholsom's more

0:54:38.040 --> 0:54:42.520
<v Speaker 1>speculative Weirder strategies, in which the company would lease modular

0:54:42.600 --> 0:54:45.919
<v Speaker 1>concrete pieces of buildings to their owners and reclaim them,

0:54:46.040 --> 0:54:49.120
<v Speaker 1>perhaps after fifty years or more. When the buildings come down.

0:54:49.640 --> 0:54:52.360
<v Speaker 1>The pieces could then be leased out anew to projects

0:54:52.400 --> 0:54:56.360
<v Speaker 1>yet to come. Burmeho also wanted to highlight the sustainable

0:54:56.400 --> 0:55:00.520
<v Speaker 1>products and services Wholsom was already selling. Walk Through a

0:55:00.560 --> 0:55:04.200
<v Speaker 1>series of colorful physical exhibits designed in the clear, cheerful

0:55:04.239 --> 0:55:07.879
<v Speaker 1>style of a contemporary science museum. There's stuff to see,

0:55:08.239 --> 0:55:11.759
<v Speaker 1>things to touch, and well produced videos that explain technology

0:55:11.800 --> 0:55:15.000
<v Speaker 1>the company is rolling out or developing. The main objective,

0:55:15.120 --> 0:55:18.680
<v Speaker 1>Burmejo said, is to decarbonize cement and to make use

0:55:18.680 --> 0:55:21.360
<v Speaker 1>of as little clinker as possible. But once we have

0:55:21.440 --> 0:55:24.160
<v Speaker 1>reduced clinker as much as possible, we have to build

0:55:24.200 --> 0:55:26.960
<v Speaker 1>better with less and minimize the use of concrete with

0:55:27.080 --> 0:55:31.359
<v Speaker 1>better designs. Burmeho pointed out that carbon emissions don't come

0:55:31.480 --> 0:55:35.040
<v Speaker 1>only from construction materials. For most buildings, the majority of

0:55:35.080 --> 0:55:38.560
<v Speaker 1>emissions result from running the facility, heating it, cooling it,

0:55:38.719 --> 0:55:42.480
<v Speaker 1>lighting it over time. The built environment accounts for about

0:55:42.520 --> 0:55:46.560
<v Speaker 1>forty percent of global carbon emissions, with thirteen percent generated

0:55:46.600 --> 0:55:49.399
<v Speaker 1>by erecting and repairing structures and the rest from their

0:55:49.440 --> 0:55:54.040
<v Speaker 1>ongoing use. Innovative materials are one answer to reducing the

0:55:54.080 --> 0:55:58.120
<v Speaker 1>climate impact of construction. Innovating with old materials is another.

0:55:58.680 --> 0:56:01.200
<v Speaker 1>The big idea is to use the built environment in

0:56:01.200 --> 0:56:05.760
<v Speaker 1>today's cities. As the mines for tomorrow's buildings, crushed concrete

0:56:05.840 --> 0:56:09.160
<v Speaker 1>can be used for stone, there's cement to be mined too.

0:56:09.719 --> 0:56:13.080
<v Speaker 1>In a process called re clinkering, small particles of cement

0:56:13.239 --> 0:56:15.880
<v Speaker 1>or fines that have not fully mixed with the massive

0:56:15.880 --> 0:56:19.040
<v Speaker 1>concrete can be recovered and used to reduce the amount

0:56:19.080 --> 0:56:21.880
<v Speaker 1>of new cement in a mix. Getting the technology to

0:56:21.960 --> 0:56:25.920
<v Speaker 1>produce cement at scale is a work in progress. Urban

0:56:26.080 --> 0:56:29.480
<v Speaker 1>mining with late model recycling plants that can separate and

0:56:29.560 --> 0:56:32.640
<v Speaker 1>process materials so they can be incorporated into products that

0:56:32.719 --> 0:56:35.680
<v Speaker 1>meet modern codes is growing into a big business for

0:56:35.680 --> 0:56:38.319
<v Speaker 1>Wholesome in Europe, where it has one hundred and nine

0:56:38.400 --> 0:56:43.040
<v Speaker 1>plants to recycle building materials. In Western Europe, chronically short

0:56:43.040 --> 0:56:46.680
<v Speaker 1>of space for landfill, construction and demolition, debris historically make

0:56:46.800 --> 0:56:49.920
<v Speaker 1>up about thirty eight percent of all waste that's almost

0:56:49.960 --> 0:56:53.480
<v Speaker 1>one billion tons a scale. Wholesome knows how to handle

0:56:54.040 --> 0:56:57.040
<v Speaker 1>with waste. It earns gate fees for receiving material for

0:56:57.080 --> 0:57:00.080
<v Speaker 1>its recycling plants, and it earns again when it converts

0:57:00.120 --> 0:57:04.600
<v Speaker 1>the waste into low carbon resources for construction. Burmeho saved

0:57:04.600 --> 0:57:08.720
<v Speaker 1>for last a material. Wholesome has high hopes for biochar.

0:57:09.280 --> 0:57:12.120
<v Speaker 1>A charcoal made from heating plant waste in the absence

0:57:12.120 --> 0:57:16.440
<v Speaker 1>of oxygen, leaves, sticks, tree bark, corn, cobs, manure, and

0:57:16.560 --> 0:57:20.600
<v Speaker 1>more can be converted to biochar because plants absorb CO

0:57:20.880 --> 0:57:24.920
<v Speaker 1>two through photosynthesis as they grow. Biochar made from plant

0:57:24.960 --> 0:57:30.400
<v Speaker 1>material contains carbon, making biochar usually but not always, releases

0:57:30.480 --> 0:57:33.600
<v Speaker 1>some CO two, but as much as ten times more

0:57:33.640 --> 0:57:37.040
<v Speaker 1>carbon is sequestered in It lock biochar up in the

0:57:37.040 --> 0:57:40.919
<v Speaker 1>massive concrete, and the carbon is entombed too. It also

0:57:41.000 --> 0:57:44.440
<v Speaker 1>makes concrete stronger, more durable, and more resistant to the

0:57:44.520 --> 0:57:48.560
<v Speaker 1>kind of cracking that afflicts concrete reinforced with steel. What

0:57:48.640 --> 0:57:51.560
<v Speaker 1>excites bur Maho most is that the concrete produced with

0:57:51.640 --> 0:57:56.440
<v Speaker 1>biochar can help make concrete carbon negative, sequestering more carbon

0:57:56.520 --> 0:57:59.480
<v Speaker 1>than is emitted in its production. The company has already

0:57:59.520 --> 0:58:03.400
<v Speaker 1>produced a carbon neutral concrete with three percent biochar made

0:58:03.440 --> 0:58:07.200
<v Speaker 1>from wastewood from tree trimmings and coffee grounds. The mix

0:58:07.280 --> 0:58:12.600
<v Speaker 1>also incorporated some low carbon sementitious materials. A newly patented

0:58:12.640 --> 0:58:16.280
<v Speaker 1>technology developed at Washington State University by Shan Ming Shi

0:58:16.720 --> 0:58:19.760
<v Speaker 1>can pre treat biochar chemically so that a mix with

0:58:19.840 --> 0:58:22.960
<v Speaker 1>ten percent biochar can negate all the co two in

0:58:23.000 --> 0:58:26.720
<v Speaker 1>an otherwise standard Portland cemit concrete. It's yet to be

0:58:26.800 --> 0:58:31.000
<v Speaker 1>tried in the wild Burmejo set. Using biochar has one

0:58:31.160 --> 0:58:34.600
<v Speaker 1>very big catch. There isn't enough of it available. The

0:58:34.640 --> 0:58:38.080
<v Speaker 1>world supply of bio waste is huge, but there's little

0:58:38.080 --> 0:58:41.400
<v Speaker 1>infrastructure to move and process it. In the future, we

0:58:41.520 --> 0:58:44.360
<v Speaker 1>might be saving our lawn waste, coffee grounds and even

0:58:44.440 --> 0:58:48.680
<v Speaker 1>dog feces to send for biochar conversion. Thus, will we

0:58:48.800 --> 0:58:55.280
<v Speaker 1>do our bit to decarbonize construction? Thirteen shopping concrete streaked.

0:58:56.240 --> 0:58:59.560
<v Speaker 1>Watching the Poi Islanders shore up their island with concrete

0:58:59.680 --> 0:59:01.880
<v Speaker 1>feel it's a bit like viewing a time lapse movie

0:59:01.960 --> 0:59:04.640
<v Speaker 1>of how the material spread so quickly around the world.

0:59:05.360 --> 0:59:08.680
<v Speaker 1>Every day, converted wooden fishing boats pull into the island's

0:59:08.800 --> 0:59:12.480
<v Speaker 1>narrow port, where men in shorts, football jerseys and flip

0:59:12.480 --> 0:59:17.040
<v Speaker 1>flops unload bags of cement and aerated lightweight concrete bricks.

0:59:17.720 --> 0:59:20.920
<v Speaker 1>Concrete is the stuff of the islander's aspirations for a

0:59:20.960 --> 0:59:25.240
<v Speaker 1>better life. It's also indispensable to their security. They need

0:59:25.280 --> 0:59:27.360
<v Speaker 1>it to protect Pari from the grip of the sea,

0:59:27.720 --> 0:59:30.200
<v Speaker 1>from the harms of the world. Using ever more of it.

0:59:30.800 --> 0:59:34.480
<v Speaker 1>Almost all of Parri Island's traditional wood and bamboo houses

0:59:34.680 --> 0:59:38.240
<v Speaker 1>have been replaced with small, hard walled, hard floored ones,

0:59:38.800 --> 0:59:41.760
<v Speaker 1>with concrete made from bag cement for the foundations and

0:59:41.840 --> 0:59:44.640
<v Speaker 1>blocks for the walls. Workers can build a sturdy home

0:59:44.720 --> 0:59:48.520
<v Speaker 1>in days. The island's fishermen and farmers can surrender these

0:59:48.640 --> 0:59:52.200
<v Speaker 1>when booked to the growing throngs of frugal Jakarta tourists.

0:59:52.760 --> 0:59:56.280
<v Speaker 1>These people need electrical outlets to charge their phones. They

0:59:56.280 --> 0:59:59.480
<v Speaker 1>want Wi Fi and air conditioning. They expect hard surfaced

0:59:59.560 --> 1:00:05.320
<v Speaker 1>lavatory and walls. Concrete enables those amenities. A future of

1:00:05.400 --> 1:00:08.480
<v Speaker 1>rising seas is also a future of enormous sea walls,

1:00:08.840 --> 1:00:13.360
<v Speaker 1>human made barrier islands, infrastructure for flood control, and resilient

1:00:13.400 --> 1:00:17.880
<v Speaker 1>homes for the world's one billion coastal residents. Population centers

1:00:17.920 --> 1:00:21.160
<v Speaker 1>with threatened coasts are or will be embarking on some

1:00:21.200 --> 1:00:24.680
<v Speaker 1>of the most expensive and concrete intensive projects of all time.

1:00:25.320 --> 1:00:28.480
<v Speaker 1>A recently completed twelve billion dollar network of sea walls

1:00:28.480 --> 1:00:31.960
<v Speaker 1>in Japan is two hundred and fifty miles long, forty

1:00:32.040 --> 1:00:34.840
<v Speaker 1>nine feet high above the water and eighty two feet

1:00:34.880 --> 1:00:39.160
<v Speaker 1>below the seafloor. Over the next fifty to one hundred years. Singapore,

1:00:39.400 --> 1:00:42.320
<v Speaker 1>in the same climate zone as Pari Island, expects to

1:00:42.320 --> 1:00:46.600
<v Speaker 1>spend one hundred billion dollars on defenses, including seawalls, tidal gates,

1:00:46.840 --> 1:00:50.919
<v Speaker 1>pumping stations, and coastal barriers. Other cities, such as New York,

1:00:51.120 --> 1:00:54.120
<v Speaker 1>are in similar need. Both Singapore and New York have

1:00:54.200 --> 1:00:58.800
<v Speaker 1>pledged to use more sustainable concrete mixes. How much cement

1:00:58.880 --> 1:01:01.320
<v Speaker 1>the world will produce in the coming decades is an

1:01:01.360 --> 1:01:05.600
<v Speaker 1>open question. Production has dropped almost ten percent since twenty twenty,

1:01:06.000 --> 1:01:09.320
<v Speaker 1>largely because of the scaling back of Chinese demand, but

1:01:09.440 --> 1:01:12.520
<v Speaker 1>population growth and the expansion of the global middle class

1:01:12.760 --> 1:01:17.080
<v Speaker 1>suggests the reversal runs against the longer term trend. Architecture

1:01:17.080 --> 1:01:20.480
<v Speaker 1>twenty thirty, a research organization that set the climate goals

1:01:20.480 --> 1:01:23.680
<v Speaker 1>for the American Institute of Architects, estimates that by twenty

1:01:23.760 --> 1:01:26.840
<v Speaker 1>sixty the world will have constructed enough new buildings to

1:01:26.880 --> 1:01:30.080
<v Speaker 1>add two point six trillion square feet of floor space.

1:01:30.480 --> 1:01:33.280
<v Speaker 1>That's roughly double the floor area of all buildings that

1:01:33.360 --> 1:01:37.600
<v Speaker 1>exist today. The UN Environment Program estimates the world cities

1:01:37.600 --> 1:01:39.920
<v Speaker 1>will be home to two and a half billion additional

1:01:39.920 --> 1:01:45.040
<v Speaker 1>inhabitants by twenty fifty Extrapolating from that figure, engineering software

1:01:45.040 --> 1:01:48.800
<v Speaker 1>maker Autodesk has calculated that the construction industry will need

1:01:48.840 --> 1:01:52.200
<v Speaker 1>to build an average of thirteen thousand buildings every day

1:01:52.640 --> 1:01:56.040
<v Speaker 1>and construct seven hundred thousand miles of roads and nearly

1:01:56.160 --> 1:02:00.320
<v Speaker 1>ninety thousand bridges every year by mid century. More than

1:02:00.400 --> 1:02:03.880
<v Speaker 1>half the mass of what's coming will likely be concrete,

1:02:04.160 --> 1:02:06.920
<v Speaker 1>and that doesn't include the cement and concrete needed to

1:02:06.960 --> 1:02:12.439
<v Speaker 1>fix what the world has already built. Fourteen alt Rock

1:02:13.400 --> 1:02:17.760
<v Speaker 1>can wholesome decarbonize faster as the Pari Islander's lawsuit demands.

1:02:18.360 --> 1:02:22.480
<v Speaker 1>A universe of natural and post industrial materials already lowers

1:02:22.480 --> 1:02:25.560
<v Speaker 1>the clinker factor in the company's cement and concrete, as

1:02:25.600 --> 1:02:28.680
<v Speaker 1>well as in much of the worlds. Like clinker, these

1:02:28.720 --> 1:02:32.720
<v Speaker 1>materials are cementitious. They react and bind materials in a

1:02:32.760 --> 1:02:37.560
<v Speaker 1>concrete mix in ways that ape Portland cement. These materials don't, however,

1:02:37.840 --> 1:02:42.120
<v Speaker 1>require additional carbon intensive preparation to work. Many of these

1:02:42.200 --> 1:02:45.920
<v Speaker 1>materials are in the broad class called pozzolans, after the

1:02:45.960 --> 1:02:50.240
<v Speaker 1>Italian town of Potswooli, a source of ash for Roman concrete.

1:02:50.600 --> 1:02:54.600
<v Speaker 1>The most used natural pozzolands are some form of volcanic ash.

1:02:55.040 --> 1:02:58.360
<v Speaker 1>They are abundant where volcanoes still erupt and also where

1:02:58.480 --> 1:03:02.560
<v Speaker 1>volcanoes were active in previews as geological ages. Southern Europe

1:03:02.560 --> 1:03:06.280
<v Speaker 1>and the western US are rich in them. Potzolins generally

1:03:06.280 --> 1:03:08.919
<v Speaker 1>can't act like cement on their own, but they take

1:03:08.960 --> 1:03:12.600
<v Speaker 1>on binding powers when mixed with cement and water. A

1:03:12.640 --> 1:03:17.120
<v Speaker 1>potzelan can also be manufactured by kilning kolin clay, including

1:03:17.200 --> 1:03:21.240
<v Speaker 1>varieties already widely used in ceramics and other industrial products.

1:03:21.840 --> 1:03:25.160
<v Speaker 1>The world has an abundant supply of klin clay, even

1:03:25.200 --> 1:03:29.320
<v Speaker 1>in places where limestone is scarce. Raw klin clays don't

1:03:29.320 --> 1:03:33.080
<v Speaker 1>contain carbon, but baking them changes their molecular structure, and

1:03:33.480 --> 1:03:36.200
<v Speaker 1>with the addition of some Portland cement to kick them off,

1:03:36.520 --> 1:03:40.320
<v Speaker 1>makes them reactive in a concrete mix. Once reactive, it's

1:03:40.400 --> 1:03:44.360
<v Speaker 1>called meadow kalin. Not only does it start carbon free,

1:03:44.520 --> 1:03:47.560
<v Speaker 1>but it's processed in kilns heated no higher than fifteen

1:03:47.640 --> 1:03:50.840
<v Speaker 1>hundred and sixty degrees fahrenheit, which means the kilns can

1:03:50.920 --> 1:03:56.200
<v Speaker 1>run on renewable electric power. Even raw, unprocessed limestone, though

1:03:56.200 --> 1:04:00.160
<v Speaker 1>not a pozzolin, can become cementitious when finely ground and

1:04:00.240 --> 1:04:04.720
<v Speaker 1>mixed with Portland cement in Western Europe, ground limestone routinely

1:04:04.760 --> 1:04:08.480
<v Speaker 1>replaces six to thirty five percent of Portland cement. In

1:04:08.520 --> 1:04:12.320
<v Speaker 1>the US, it often replaces five to fifteen percent. A

1:04:12.360 --> 1:04:16.080
<v Speaker 1>recent breakthrough allows a mixture of ground limestone and medocalin

1:04:16.200 --> 1:04:20.920
<v Speaker 1>clay to replace half of Portland cement. Other reactive supplements

1:04:20.920 --> 1:04:25.240
<v Speaker 1>are being created with micronization, a process that grinds materials

1:04:25.280 --> 1:04:29.600
<v Speaker 1>into ultrafine particles. A concrete blockmaker in Brooklyn, New York,

1:04:29.880 --> 1:04:34.240
<v Speaker 1>Glenwood Mason Supply used micronized waste glass to make more

<v Speaker 1>Lower Manhattan. Ozinga Brothers, a large concrete producer based outside Chicago,

1:04:42.320 --> 1:04:46.560
<v Speaker 1>is building America's first large micronizing grinder for slag to

1:04:46.640 --> 1:04:51.600
<v Speaker 1>replace large portions of Portland cement used optimally. Materials on

<v Speaker 1>US states, however, including California, Colorado, New York, and Washington,

1:05:20.600 --> 1:05:25.640
<v Speaker 1>specify low carbon concrete for public works. Other influential buyers

<v Speaker 1>of low carbon materials today are so called hyperscalers alphabet Amazon,

1:05:30.840 --> 1:05:35.880
<v Speaker 1>Web services, meta platforms, Microsoft and Oracle, among others, rushing

1:05:35.920 --> 1:05:39.160
<v Speaker 1>to build huge, concrete heavy data centers for their artificial

1:05:39.200 --> 1:05:43.160
<v Speaker 1>intelligence infrastructure. The US operations of a company such as

1:05:43.240 --> 1:05:46.920
<v Speaker 1>Amrise can sell lower carbon cement to the American projects

1:05:46.920 --> 1:05:50.200
<v Speaker 1>that demand it, and higher carbon cement where clients choose

1:05:50.240 --> 1:05:54.400
<v Speaker 1>that It's possible and probably likely that the global cement

1:05:54.440 --> 1:05:58.800
<v Speaker 1>industry won't get to net zero emissions by twenty fifty. Still,

1:05:59.000 --> 1:06:02.920
<v Speaker 1>there's cause for optimism that decarbonization, not just of cement,

1:06:03.040 --> 1:06:07.440
<v Speaker 1>but more generally, can progress. Concrete will certainly be needed

1:06:07.440 --> 1:06:10.040
<v Speaker 1>if other industries are going to be powered by sources

1:06:10.120 --> 1:06:14.720
<v Speaker 1>other than fossil fuels. The infrastructures of wind energy, nuclear power,

1:06:14.760 --> 1:06:19.120
<v Speaker 1>and hydroelectric power all require enormous amounts of concrete. In

1:06:19.160 --> 1:06:22.600
<v Speaker 1>each case, the carbon emissions associated with the manufacture of

1:06:22.640 --> 1:06:26.080
<v Speaker 1>that concrete is trivial compared with the far greater carbon

1:06:26.080 --> 1:06:33.600
<v Speaker 1>emissions averted fifteen good bones imagine now if concrete were

1:06:33.680 --> 1:06:36.800
<v Speaker 1>far more than a structural material, that it also could

1:06:36.840 --> 1:06:41.320
<v Speaker 1>be used to store and generate renewable energy. Admere Message,

1:06:41.480 --> 1:06:45.280
<v Speaker 1>a leading investigator at the Massachusetts Institute of Technologies Concrete

1:06:45.320 --> 1:06:49.880
<v Speaker 1>sustainability hub lichens concrete to living bones in the body.

1:06:50.520 --> 1:06:53.960
<v Speaker 1>I need bones for strength, he says. They're load bearing,

1:06:54.320 --> 1:06:57.680
<v Speaker 1>but their functions arose after millennia of trial and error,

1:06:57.960 --> 1:07:02.600
<v Speaker 1>and their multifunctional bones channel energy. They give us transportation,

1:07:03.000 --> 1:07:05.680
<v Speaker 1>and they are the engines for blood making. We can

1:07:05.720 --> 1:07:10.960
<v Speaker 1>think about concrete the same way as multifunctional. Massach's work

1:07:11.040 --> 1:07:14.160
<v Speaker 1>on the structure of concrete led him together with MIT

1:07:14.200 --> 1:07:18.160
<v Speaker 1>colleagues Franz Joseph Ulm and Hissam Azari Jafari, to seek

1:07:18.200 --> 1:07:21.440
<v Speaker 1>ways to use the material for energy storage. The idea,

1:07:21.520 --> 1:07:25.200
<v Speaker 1>in effect, is to turn buildings into giant supercapacitors that

1:07:25.320 --> 1:07:30.120
<v Speaker 1>can store energy for renewable sources. Despite its solidity, concrete

1:07:30.200 --> 1:07:34.520
<v Speaker 1>is replete with tiny spaces distributed throughout its mass. These,

1:07:34.720 --> 1:07:38.040
<v Speaker 1>the scientists discovered, can be filled with electrolytes and an

1:07:38.080 --> 1:07:42.840
<v Speaker 1>ultrafined carbon powder called carbon black. Their materials that can,

1:07:42.920 --> 1:07:46.400
<v Speaker 1>for instance, store power generated in the daytime by wind

1:07:46.440 --> 1:07:50.000
<v Speaker 1>and solar sources, then release it at night. The floor

1:07:50.040 --> 1:07:53.280
<v Speaker 1>slab of a typical American basement could hold enough energy

1:07:53.320 --> 1:07:56.320
<v Speaker 1>to power a home for a full day. The bases

1:07:56.360 --> 1:08:00.400
<v Speaker 1>of wind turbines could be turned into batteries roads too.

1:08:00.560 --> 1:08:04.800
<v Speaker 1>Concrete highways impregnated with energy storing carbon can be engineered

1:08:04.840 --> 1:08:07.960
<v Speaker 1>to emit power to charge electric cars as they speed by.

1:08:08.680 --> 1:08:12.320
<v Speaker 1>The concrete in effect becomes a huge wireless power block.

1:08:13.040 --> 1:08:16.280
<v Speaker 1>MIT has set up a new hub to commercialize the innovation.

1:08:17.520 --> 1:08:21.200
<v Speaker 1>Concrete may be the world's most used manufactured product, but

1:08:21.360 --> 1:08:24.519
<v Speaker 1>crushed stone, gravel, and sand are the most used raw

1:08:24.600 --> 1:08:28.759
<v Speaker 1>resources together, totaling forty four to fifty four billion tons

1:08:28.800 --> 1:08:32.160
<v Speaker 1>a year. What if instead of mining limestone, we made

1:08:32.200 --> 1:08:36.600
<v Speaker 1>it from industrial carbon dioxide emissions. Blue Planet Systems, a

1:08:36.640 --> 1:08:40.920
<v Speaker 1>company in California, has patented technology that mimics how organisms

1:08:40.920 --> 1:08:45.519
<v Speaker 1>biomineralize carbon and calcium into shells and exoskeletons that, over

1:08:45.560 --> 1:08:48.600
<v Speaker 1>time turn into the limestone that's out in the wild.

1:08:48.920 --> 1:08:51.360
<v Speaker 1>The aim is to make new limestone that can be

1:08:51.479 --> 1:08:54.880
<v Speaker 1>used as the stone in concrete or distributed in places

1:08:54.920 --> 1:08:58.160
<v Speaker 1>where small rocks serve as a bed covering or barrier,

1:08:58.400 --> 1:09:01.440
<v Speaker 1>such as under roads and railroad tess eyes, in landscaping

1:09:01.520 --> 1:09:05.479
<v Speaker 1>and along waterways. Blue Planet collects the calcium it needs

1:09:05.560 --> 1:09:09.400
<v Speaker 1>from concrete construction waste, and sources CO two from carbon

1:09:09.439 --> 1:09:13.519
<v Speaker 1>capture projects used in concrete. The new stone can make

1:09:13.560 --> 1:09:17.120
<v Speaker 1>that material carbon negative, but Blue Planet is still at

1:09:17.200 --> 1:09:19.680
<v Speaker 1>least five years away from producing at a scale that

1:09:19.720 --> 1:09:22.680
<v Speaker 1>will make a meaningful dent in CO two emissions, and

1:09:22.760 --> 1:09:25.360
<v Speaker 1>it still needs to convince investors and buyers that its

1:09:25.400 --> 1:09:30.240
<v Speaker 1>economics work. Its technology has vast climate healing potential, given

1:09:30.280 --> 1:09:33.000
<v Speaker 1>that each year the world minds about twenty two billion

1:09:33.080 --> 1:09:36.960
<v Speaker 1>tons of gravel. Using captured CO two to replace even

1:09:37.000 --> 1:09:40.920
<v Speaker 1>a moderate fraction of that could negate gigatons thousands of

1:09:40.960 --> 1:09:44.639
<v Speaker 1>megatons of CO two. The company has some big backers,

1:09:44.680 --> 1:09:49.120
<v Speaker 1>including Amorrihise. Marathon Petroleum has also joined to help commercialize

1:09:49.160 --> 1:09:54.559
<v Speaker 1>the technology and bring it to scale sixteen trials ahead.

1:09:55.320 --> 1:09:58.760
<v Speaker 1>The most daunting challenge of taking on global carbon emissions

1:09:59.000 --> 1:10:02.759
<v Speaker 1>is how many parties need to align. Wholesome alone can't

1:10:02.800 --> 1:10:05.840
<v Speaker 1>reverse the fate of Pirie Island, and certainly not by

1:10:05.880 --> 1:10:08.040
<v Speaker 1>paying for only er point forty two percent of the

1:10:08.120 --> 1:10:12.960
<v Speaker 1>damage suffered by four struggling people forcing more aggressive carbon

1:10:13.040 --> 1:10:16.040
<v Speaker 1>goals on the company won't produce any real relief either,

1:10:16.520 --> 1:10:19.880
<v Speaker 1>unless that is as Mania at all. The wholesome does

1:10:20.000 --> 1:10:23.839
<v Speaker 1>open the floodgates to successful litigation and political action against

1:10:23.880 --> 1:10:27.519
<v Speaker 1>other carbon majors. The full trial is expected to begin

1:10:27.680 --> 1:10:31.479
<v Speaker 1>in October. Would the people of Parri Island trade back

1:10:31.560 --> 1:10:34.160
<v Speaker 1>the benefits of concrete for the chance at not having

1:10:34.200 --> 1:10:37.800
<v Speaker 1>to muddle through the stuff's contribution to climate change. They might,

1:10:38.320 --> 1:10:40.880
<v Speaker 1>They might not. Would the world give up on the

1:10:41.040 --> 1:10:44.439
<v Speaker 1>enormous benefits of concrete, including its role in a future

1:10:44.439 --> 1:10:49.360
<v Speaker 1>of renewable, low carbon energy. It cannot. On the narrow

1:10:49.439 --> 1:10:52.760
<v Speaker 1>streets and gangways of Parrie Island today, the basics of

1:10:52.800 --> 1:10:58.000
<v Speaker 1>concrete construction are everywhere. Unopened bags of cement sit lumpish,

1:10:58.120 --> 1:11:00.600
<v Speaker 1>one or two at a time, in small yards or

1:11:00.640 --> 1:11:02.880
<v Speaker 1>sometimes just in the middle of a path where no

1:11:02.920 --> 1:11:06.759
<v Speaker 1>one disturbs them. Shoulder high bins of sharp broken coral

1:11:06.800 --> 1:11:11.160
<v Speaker 1>await their concrete stew Women in dusty aprons and scarves

1:11:11.240 --> 1:11:16.040
<v Speaker 1>improvise concrete defenses against floods. Men on ladders inside newly

1:11:16.080 --> 1:11:20.679
<v Speaker 1>built homes plaster over concrete block walls, wielding knives, trowels

1:11:20.720 --> 1:11:24.960
<v Speaker 1>and long fingernails to craft vaguely Italianate or Arabesque moldings.

1:11:25.680 --> 1:11:28.960
<v Speaker 1>For more than a century. Concrete's combination of solidity and

1:11:29.000 --> 1:11:32.759
<v Speaker 1>plasticity has made it a medium for almost unbounded innovation

1:11:32.880 --> 1:11:37.120
<v Speaker 1>and creativity. Its components mix and match in endless ways.

1:11:37.720 --> 1:11:42.400
<v Speaker 1>Its endless applications require endless problem solving. There are no

1:11:42.560 --> 1:11:46.280
<v Speaker 1>other possible building materials on Earth that could rival concrete

1:11:46.439 --> 1:11:49.679
<v Speaker 1>in scale. By the end of the century, the world's

1:11:49.720 --> 1:11:52.519
<v Speaker 1>population is predicted to grow by two billion to three

1:11:52.600 --> 1:11:57.520
<v Speaker 1>billion people, depending on fertility rates. Many will live in megacities,

1:11:57.840 --> 1:12:01.360
<v Speaker 1>those with at least ten million people. The UK advisory

1:12:01.400 --> 1:12:05.519
<v Speaker 1>company Oxford Economics predicts that today's forty four megacities will

1:12:05.520 --> 1:12:08.639
<v Speaker 1>grow to sixty seven by twenty fifty, and their total

1:12:08.680 --> 1:12:12.200
<v Speaker 1>population will climb by two hundred and sixty six million people.

1:12:13.040 --> 1:12:16.880
<v Speaker 1>Concrete in such places teams and burgeons so quickly it

1:12:16.920 --> 1:12:20.439
<v Speaker 1>can seem like a giant living organism, not only creative

1:12:20.520 --> 1:12:24.760
<v Speaker 1>but procreative. Yet it's all the result of our generative powers.

1:12:25.240 --> 1:12:28.040
<v Speaker 1>The world has all the creativity it needs to marshal

1:12:28.080 --> 1:12:31.680
<v Speaker 1>cement and concrete against the floods on Pari Island and

1:12:31.720 --> 1:12:35.240
<v Speaker 1>the threat of a global climate catastrophe. The task is

1:12:35.320 --> 1:12:38.200
<v Speaker 1>smaller than what's been accomplished with the materials so far.

1:12:38.880 --> 1:12:42.520
<v Speaker 1>The scale of the benefit would dwarf even that of concrete.

1:12:43.800 --> 1:12:46.599
<v Speaker 1>Tedsea Fishman is writing a book for w W. Norton

1:12:46.640 --> 1:12:50.559
<v Speaker 1>about concrete's role shaping modern civilization and our future on

1:12:50.640 --> 1:12:51.200
<v Speaker 1>the planet.
