Is America Ready for ‘Degrowth Communism’?

News Feed
Tuesday, May 28, 2024

Kohei Saito knows he sounds like a madman. That’s kind of the point, the Japanese philosopher told me during a recent visit to New York City. “Maybe, then, people get shocked,” he said. “What’s this crazy guy saying?”The crazy idea is “degrowth communism,” a combination of two concepts that are contentious on their own. Degrowth holds that there will always be a correlation between economic output and carbon emissions, so the best way to fight climate change is for wealthy nations to cut back on consumption and reduce the “material throughput” that creates demand for energy and drives GDP.The degrowth movement has swelled in recent years, particularly in Europe and in academic circles. The theory has dramatic implications. Instead of finding carbon-neutral ways to power our luxurious modern lifestyles, degrowth would require us to surrender some material comforts. One leading proponent suggests imposing a hard cap on total national energy use, which would ratchet down every year. Energy-intensive activities might be banned outright or taxed to near oblivion. (Say goodbye, perhaps, to hamburgers, SUVs, and your annual cross-country flight home for the holidays.) You’d probably be prohibited from setting the thermostat too cold in summer or too warm in winter. To keep frivolous spending down, the government might decide which products are “wasteful” and ban advertising for them. Slower growth would require less labor, so the government would shorten the workweek and guarantee a job for every person.Saito did not invent degrowth, but he has put his own spin on it by adding the C word.As for what kind of “communism” we’re talking about, Saito tends to emphasize workers’ cooperatives and generous social-welfare policies rather than top-down Leninist state control of the economy. He says he wants democratic change rather than revolution—though he’s fuzzy on how exactly you get people to vote for shrinkage.This message has found an enthusiastic audience. Saito’s 2020 book, Capital in the Anthropocene, sold half a million copies. He took a job at the prestigious University of Tokyo and became a regulator commentator on Japanese TV—one of the few far-left talking heads in that country’s conservative media sphere. When we met up in April, he was touring the northeastern U.S. to promote the new English translation of the book, titled Slow Down: The Degrowth Manifesto, and planning to appear on a series of panels at Georgetown University to discuss his ideas. One day during his New York stint, we visited the pro-Palestinian protests at Columbia University, where a young protester named Tianle Zhang spotted him and waved him over, telling Saito he’s the reason he’s applying to graduate school. They took a selfie together and Saito posted it on X.Saito’s haters are just as passionate as his admirers. The right-wing podcaster James Lindsay recently dedicated a three-hour episode to what he called Saito’s “death cult.” Liberals who favor renewable energy and other technologies say Saito’s ideas would lead to stagnation. On the pro-labor left, Jacobin magazine published multiple pieces criticizing degrowth in general and Saito in particular, calling his vision a “political disaster” that would hurt the working class. And don’t get the Marxist textualists started; they accuse Saito of distorting the great man’s words in order to portray Marx as the OG degrowth communist.It’s understandable why Saito provokes so much ire: He rejects the mainstream political consensus that the best way to fight climate change is through innovation, which requires growth. But no matter how many times opponents swat it down, the idea of degrowth refuses to die. Perhaps it survives these detailed, technical refutations because its very implausibility is central to its appeal.Economic growth, the French economist Daniel Cohen has written, is the religion of the modern world. Growth is the closest thing to an unalloyed good as exists in politics or economics. It’s good for the rich, and it’s good for the poor. It’s good if you believe inequality is too high, and if you think inequality doesn’t matter. Deciding how to distribute wealth is complicated, but in theory it gets easier when there’s more wealth to distribute. Growth is the source of legitimacy for governments across the political spectrum: Keep us in power, and we’ll make your life better.Japan has worshipped as devoutly as anyone. After the country’s defeat in World War II, GDP replaced military might as a source of national pride. Japan’s economy grew at a rate of nearly 10 percent until the 1970s and remained strong through the 1980s as its automotive and electronics industries boomed. So when the Asian financial bubble burst and the Japanese economy collapsed in the early 1990s, the country faced not just an economic crisis, but a crisis of meaning. If Japan wasn’t growing, what was it?[Read: Does the economy really need to stop growing quite so much?]Saito was born in 1987, just before the crash, and he grew up in a time of stagnation. As a student at a private all-boys secondary school, his politics were moderate, he says. He thought of problems like inequality and consumerism in terms of individual moral failings rather than as the consequences of policy choices. But the war in Iraq got him reading Noam Chomsky, college introduced him to Marx, and the 2008 financial crisis spurred him to question the capitalist system. Saito briefly enrolled at the University of Tokyo, but transferred to Wesleyan University, which he found insufficiently radical, on a scholarship. He graduated in 2009.The 2011 earthquake and nuclear disaster at Fukushima pushed Saito to reconsider humanity’s relationship with nature. “Fukushima caused me to question whether technology and the increase of productive forces create a better society,” he said. “The answer was no.”Saito moved to Berlin and got his Ph.D. at Humboldt University, where he studied Marx’s views on ecology. In 2016, he published an academic treatise on Marx’s “ecosocialism,” the English translation of which won the prestigious Deutscher Memorial Prize for books in the Marxist tradition.Around that time, the idea of degrowth, which had been kicking around environmentalist circles for decades, was gaining steam in Europe. Saito started reading thinkers such as Tim Jackson, Giorgos Kallis, and Kate Raworth, all of whom argued that there are planetary boundaries we can’t exceed without causing mayhem. Thinkers since Thomas Malthus had been talking about limits to humanity’s expansion—sometimes with disturbing implications, as in Paul Ehrlich’s 1968 best seller, The Population Bomb, which described with disgust a teeming Delhi slum. But degrowthers identified the pursuit of GDP as the culprit, arguing that it fails to account for all kinds of human flourishing. Greta Thunberg amplified the degrowth message further when she mocked capitalist society’s “fairy tales of eternal economic growth.”Japan was a ripe target for these ideas. For decades, the country had been mired in low and sometimes even negative growth. The problem was no longer new, and the government’s proposed solutions—negative interest rates; trying to boost worker productivity—were losing their appeal. “A lot of young people feel like, I don’t want to work endless overtime and give up my family life and all my hobbies just to serve a corporation until I die,” says Nick Kapur, an associate professor at Rutgers University at Camden who studies modern Japanese history. “For what? Just to grow our GDP?”  Saito saw an opening: to connect degrowth with the Marxist ideas that he had been studying closely for years. Degrowth on its own had bad branding, he told me between bites of Beyond Burger at Tom’s Restaurant in Morningside Heights. The solution, he said with a grin, was to add “another very negative term: communism.”When we met, Saito had traded his usual blazer and clean-cut look for an oversize denim jacket and a boy-band tousle. He has a disarming sense of humor: When he signs a book, he stamps it with a cartoon image of himself alongside Marx. But he’s serious about the need to embrace degrowth communism. He argues, not unreasonably, that degrowth is incompatible with capitalism, which encourages individuals to act selfishly and grow their riches. “Many people criticize neoliberalism,” Saito said. “But they don’t criticize capitalism. So that’s why we have ethical capitalism, sustainable capitalism, green capitalism.” Degrowth communism instead targets what Saito says is the root cause of our climate woes—capitalism itself—rather than just the symptoms, and prioritizes the public good over profit.While degrowthers and Marxists have plenty of intellectual overlap, the match has always been an awkward one. Marx is generally considered pro-growth: He wanted to leverage the productive tools of capitalism to bring about a socialist future in which the fruits of that production would be fairly distributed. Saito, however, rejects that “Promethean” characterization of Marx. In Capital in the Anthropocene, he instead argues that Marx converted late in life from productivism to, yes, degrowth communism. To make his case, Saito cites some of Marx’s lesser-known writings, including a draft of his 1881 letter to the Russian revolutionary writer Vera Zasulich and Critique of the Gotha Programme, which was published after Marx’s death.Saito’s book is a mishmash of political polemic, cultural criticism, and obscure Marxist exegesis. He calls individual actions like using a thermos instead of plastic water bottles “meaningless,” and mocks the UN Sustainable Development Goals, dismissing them and other market-friendly solutions as “the opiate of the masses.” Instead of relying on technology alone to save humanity, he argues, wealthy countries need to give up their consumerist lifestyles and redistribute their resources to poor countries to help them navigate the transition to a slower global economy. He advocates transitioning away from capitalism toward a “sharing economy,” and offers a mix of solutions both modest and bold. Workers should own their businesses. Citizens should control local energy production. Also: “What if Uber were publicly owned, turning its platform into a commons?” Saito argues that this arrangement would produce not scarcity but “radical abundance” as we freed ourselves from the obligation to generate ever-higher profits: “There will be more opportunities to do sports, go hiking, take up gardening, and get back in touch with nature. We will have time once again to play guitar, paint pictures, read … Compared to cramming ourselves into crowded subways every morning and eating our deli lunches in front of our computers as we work nonstop for hours and hours every day, this is clearly a richer lifestyle.”On a superficial level, Saito put a fresh young face on old environmentalist ideas. Well spoken and self-deprecating, he didn’t have the off-putting self-seriousness of many ideologues. After years of ineffective stimulus and grind culture, Saito’s ideas may have intrigued Japanese audiences looking for “the opposite of the status quo,” Nick Kapur told me. Saito’s analysis also offered a kind of tonic for Japan’s national neurosis around slow growth: What if this is good, actually? On a recent Saturday, Saito sat onstage at the People’s Forum, a community center in New York’s Chelsea neighborhood, along with three other panelists: a historian, a geographer, and a journalist from The New Republic. It was a friendly crowd, but each of the panelists cast gentle doubt on Saito’s pitch. The historian said he’d like to see more modeling of the impact of degrowth policies; the geographer wondered how a degrowth agenda would ever expand beyond small, local experiments; and the journalist, Kate Aronoff, suggested that degrowth had a branding problem.Saito had just begun his U.S. tour, and he was already encountering more resistance than he’d expected. “One thing surprising about American culture is they’re really anti-degrowth,” Saito told me after the event, as we walked along a chaotic stretch of 9th Avenue. When an American writer recently laced into him online, Saito’s European friends came to his defense. But here he was more isolated.The simplest case against degrowth is that it’s not necessary. The prospect of boosting GDP while reducing emissions—known as “decoupling”—used to look like a moon shot. But now it’s happening. In more than 30 countries, including the United States and much of Europe, emissions are declining while GDP climbs, even when you factor in the “consumption-based emissions” generated in places that manufacture goods for rich countries. Solar and wind are cheaper in the U.S. than fossil fuels. Electric vehicles, for all their struggles, will make up half of global car sales by 2035, according to one recent estimate. Decoupling still isn’t happening nearly fast enough to meet the goals of the Paris Agreement, but green-growthers argue that we can speed up the process with enough investment. “It’s easy to say we need a socialist revolution to solve the climate crisis, but that’s not going to happen in the timescale,” says Robert Pollin, a progressive economist at the University of Massachusetts at Amherst who co-authored a book with Noam Chomsky on the Green New Deal.Other detractors say that degrowth would be actively harmful. It’s one thing to ask billionaires to cut back, but what about everyone else? Are they supposed to abandon hope of raising their standard of living? Saito includes working-class Americans in his indictment of the “imperial mode of living” that he blames for carbon emissions. This was too much for Matt Huber, a professor of geography at Syracuse University, and the left-leaning climate journalist Leigh Phillips, who co-wrote an article for Jacobin accusing Saito of doing “capital’s work” by “dividing the international working class against itself.”Perhaps the most vicious reads of Saito target his interpretation of Marx. In the eyes of his critics, his reliance on a handful of passages in order to prove that Marx embraced degrowth communism amounts to a kind of fan fiction. One otherwise-sympathetic scholar wrote in a Marxist journal that the evidence Saito marshals is “simply not very convincing.” Huber and Leigh describe various claims about Marx’s views made by Saito as “wild,” “remarkable,” and “unsubstantiated.” Even John Bellamy Foster, the University of Oregon sociology professor who pioneered Marxist ecological studies in the 1990s and published Saito’s first book, told an interviewer that “no concrete evidence could be found of Marx actually advocating what could reasonably be called degrowth” and called Saito’s analysis “profoundly ahistorical.” (Saito responded in an email that Huber and Phillips “never read Marx’s notebooks that I investigate. Thus, they are not in a position to judge whether my claims are unsubstantiated because I am rereading Marx’s texts based on new materials.” As for Foster’s criticism, Saito wrote: “​​Marx never used the terms like degrowth, sustainability, and ecology. It is an attempt to push beyond Marx’s thought because there is no necessity to dogmatize Marx and he did not complete his work.”)The question of whether Marx was a degrowther is academic—and so is degrowth itself, unless it can find a viable political path. Right now, that path is murky at best. The next politician to win reelection by urging voters to accept a lower standard of living will be the first. In the U.S., policies like a carbon tax and a national cap-and-trade program are dead on arrival. Even in Europe, farmers are protesting environmental regulations that they say erode their livelihoods. In today’s politics, proposing sacrifice seems like an obvious form of political suicide that would only empower politicians who don’t care about climate change.Saito nonetheless insists that degrowth is politically possible. It starts small, he says, with workers’ cooperatives and citizens’ assemblies, and then spreads from city to city. Europe is already taking the lead, he says: Amsterdam recently banned building new hotels, while Paris restricted parking for SUVs. (One could fairly ask whether these are degrowth policies or just traditional forms of regulation.) The Spanish government has piloted a four-day workweek, Barcelona has introduced car-free “superblocks,” and the Spanish city of Girona has begun to explore how to implement “post-growth policies.” Saito says success is simply a matter of convincing a critical mass of citizens to push for degrowth. He cites the statistic popularized by the Harvard political scientist Erica Chenoweth that it only takes 3.5 percent of the population protesting to enact change.Isn’t expecting rich countries to act against their own interests a little optimistic? “Oh, yeah,” Saito said. “But the capitalist alternative is much more optimistic.” For Saito, the long-term alternative to degrowth communism is not green growth but “climate fascism,” in which countries lock down, hoard their resources, and disregard the collective good. Faced with that prospect, humanity will make the right choice. “As a philosopher,” he said, “I want to believe in the universality of reason.”Saito does propose a few concrete fixes: Ban private jets. Get rid of advertising for harmful goods and services, such as cosmetic surgery. Enact a four-day workweek. Encourage people to own one car, instead of two or three. Require shopping malls to close on Sundays, to cut down on the time available for excessive consumption. “These things won’t necessarily dismantle capitalism,” he said. “But it’s something we can do over the long term to transform our values and culture.”Of course, transforming values might be the heaviest lift of all. “Changing people’s preferences is really hard,” Dietrich Vollrath, an economist at the University of Houston who studies growth, told me. “You don’t need to change people’s preferences if you just make solar really cheap.” The Harvard economist Benjamin Friedman, who wrote The Moral Consequences of Economic Growth, says people fundamentally care about raising their material living standards and always will. “Trying to reform humanity is not a project of much interest to economists,” he told me. “We talk about what to do, not how to wish for another form of human being.”Saito admits that he might be overshooting. He isn’t expecting countries to scale down in the next decade, but maybe after that. He’s not opposed to green-energy subsidies; he just wants degrowth to be part of the conversation. He emphasized that his ideas aren’t designed with realism in mind. “I’m not an activist,” he said. “I’m a scholar.” His job is to provide the theory behind the change. Making it work is up to others.Degrowthers like Saito seem to be caught in a double dilemma. They bristle at the suggestion that degrowth would take us back to premodern standards of living—yet in trying to dispel that notion, they narrow their vision so far that it resembles business-as-usual left-of-center politics. A typical rundown of degrowth policies looks like a wish list from the Democratic Socialists of America: health care for all, universal basic income, a smaller military, mutual aid, better public transportation, decolonization, and so on. Adherents reject the view that degrowth would require some authoritarian power to impose it, but have yet to articulate a political plan besides changing one mind at a time.“At bottom it’s not actually an evidence-based agenda,” Ted Nordhaus, the founder and executive director of the Breakthrough Institute and self-described “eco-modernist,” told me. “It’s sort of a worldview and a vibe.”And yet, for many, the vibe hits. Degrowth captures a core truth of the fight against climate change: What we’re doing is not enough and might even be making things worse. Degrowth might fail too, but in the eyes of its supporters, at least it’s directionally correct. It’s the protest vote of climate activism.While in D.C., Saito co-headlined a workshop with a few dozen students at Georgetown, where they discussed degrowth. The group was mostly in favor, according to two students who attended. Fiona Naughton, a rising sophomore who studies international labor policy, told me she and many of her peers find Saito’s ideas inspiring. “A lot of us have felt such immense climate anxiety and considered whether or not we should have children,” she said. “Degrowth gives us hope for a future that we haven’t felt in a long, long time.”I also followed up with Tianle Zhang, the protester who’d taken a selfie with Saito at the Columbia rally, and asked him about how he’d discovered Saito’s work. Zhang said that as a kid in Indiana, he’d watched the news in horror as oil gushed into the Gulf of Mexico for months after the Deepwater Horizon rig exploded. In college, he’d sensed a gap between the immensity of the problem of climate change and the attempts to address it. Saito was one of the few scholars he found who was trying to connect thinking about the environment with a broader theoretical critique of capitalism and society.Zhang said he was also deeply influenced by Paul Schrader’s 2017 film, First Reformed. The film stars Ethan Hawke as a troubled priest who descends so far into climate despair that he considers committing an act of terrorism. “For me, it was showing the failures of conventional morality to handle the issue of climate,” Zhang said.[From the January/February 2023 issue: Why the age of American progress ended]Degrowth’s appeal might be similar: not political, not even economic, but moral. In the climactic final scene of First Reformed, Hawke’s character wraps himself in barbed wire as he prepares to possibly do something horrifying and futile. This seems like a fitting metaphor for not only Saito’s proposals—Saito acknowledges that degrowth would require pain—but also their psychological appeal. We have been bad, and we must atone.Beyond its stark moral claims, the very fact of degrowth’s unreasonableness gives it weight. Degrowth advocates have called it a “missile word,” designed to provoke. There’s a reason we’re talking about degrowth and not the “steady-state economy,” which environmentalists have been pushing for decades. As the prominent degrowth thinker Jason Hickel has written, the term itself upends conventional wisdom: “It is only negative if we start from the assumption that more growth is good and desirable.” To this way of thinking, the inconceivability of degrowth only highlights how trapped we are in the growth-fetishist mindset.At the end of our dinner, Saito told me he’s working on his next book, about the role of government when it comes to implementing degrowth. “The state has to intervene, but how can we make a democratic transition?” he asked rhetorically. I asked if he had an answer. He said, “Not yet.”

Kohei Saito’s theory of how to solve climate change is economically dubious and politically impossible. Why is it so popular?

Kohei Saito knows he sounds like a madman. That’s kind of the point, the Japanese philosopher told me during a recent visit to New York City. “Maybe, then, people get shocked,” he said. “What’s this crazy guy saying?

The crazy idea is “degrowth communism,” a combination of two concepts that are contentious on their own.

This was too much for Matt Huber, a professor of geography at Syracuse University, and the left-leaning climate journalist Leigh Phillips, who co-wrote an article for Jacobin accusing Saito of doing “capital’s work” by “dividing the international working class against itself.”

Perhaps the most vicious reads of Saito target his interpretation of Marx. In the eyes of his critics, his reliance on a handful of passages in order to prove that Marx embraced degrowth communism amounts to a kind of fan fiction. One otherwise-sympathetic scholar wrote in a Marxist journal that the evidence Saito marshals is “simply not very convincing.” Huber and Leigh describe various claims about Marx’s views made by Saito as “wild,” “remarkable,” and “unsubstantiated.” Even John Bellamy Foster, the University of Oregon sociology professor who pioneered Marxist ecological studies in the 1990s and published Saito’s first book, told an interviewer that “no concrete evidence could be found of Marx actually advocating what could reasonably be called degrowth” and called Saito’s analysis “profoundly ahistorical.” (Saito responded in an email that Huber and Phillips “never read Marx’s notebooks that I investigate. Thus, they are not in a position to judge whether my claims are unsubstantiated because I am rereading Marx’s texts based on new materials.” As for Foster’s criticism, Saito wrote: “​​Marx never used the terms like degrowth, sustainability, and ecology. It is an attempt to push beyond Marx’s thought because there is no necessity to dogmatize Marx and he did not complete his work.”)

The question of whether Marx was a degrowther is academic—and so is degrowth itself, unless it can find a viable political path. Right now, that path is murky at best. The next politician to win reelection by urging voters to accept a lower standard of living will be the first. In the U.S., policies like a carbon tax and a national cap-and-trade program are dead on arrival. Even in Europe, farmers are protesting environmental regulations that they say erode their livelihoods. In today’s politics, proposing sacrifice seems like an obvious form of political suicide that would only empower politicians who don’t care about climate change.

Saito nonetheless insists that degrowth is politically possible. It starts small, he says, with workers’ cooperatives and citizens’ assemblies, and then spreads from city to city. Europe is already taking the lead, he says: Amsterdam recently banned building new hotels, while Paris restricted parking for SUVs. (One could fairly ask whether these are degrowth policies or just traditional forms of regulation.) The Spanish government has piloted a four-day workweek, Barcelona has introduced car-free “superblocks,” and the Spanish city of Girona has begun to explore how to implement “post-growth policies.” Saito says success is simply a matter of convincing a critical mass of citizens to push for degrowth. He cites the statistic popularized by the Harvard political scientist Erica Chenoweth that it only takes 3.5 percent of the population protesting to enact change.

Isn’t expecting rich countries to act against their own interests a little optimistic? “Oh, yeah,” Saito said. “But the capitalist alternative is much more optimistic.” For Saito, the long-term alternative to degrowth communism is not green growth but “climate fascism,” in which countries lock down, hoard their resources, and disregard the collective good. Faced with that prospect, humanity will make the right choice. “As a philosopher,” he said, “I want to believe in the universality of reason.”

Saito does propose a few concrete fixes: Ban private jets. Get rid of advertising for harmful goods and services, such as cosmetic surgery. Enact a four-day workweek. Encourage people to own one car, instead of two or three. Require shopping malls to close on Sundays, to cut down on the time available for excessive consumption. “These things won’t necessarily dismantle capitalism,” he said. “But it’s something we can do over the long term to transform our values and culture.”

Of course, transforming values might be the heaviest lift of all. “Changing people’s preferences is really hard,” Dietrich Vollrath, an economist at the University of Houston who studies growth, told me. “You don’t need to change people’s preferences if you just make solar really cheap.” The Harvard economist Benjamin Friedman, who wrote The Moral Consequences of Economic Growth, says people fundamentally care about raising their material living standards and always will. “Trying to reform humanity is not a project of much interest to economists,” he told me. “We talk about what to do, not how to wish for another form of human being.”

Saito admits that he might be overshooting. He isn’t expecting countries to scale down in the next decade, but maybe after that. He’s not opposed to green-energy subsidies; he just wants degrowth to be part of the conversation. He emphasized that his ideas aren’t designed with realism in mind. “I’m not an activist,” he said. “I’m a scholar.” His job is to provide the theory behind the change. Making it work is up to others.

Degrowthers like Saito seem to be caught in a double dilemma. They bristle at the suggestion that degrowth would take us back to premodern standards of living—yet in trying to dispel that notion, they narrow their vision so far that it resembles business-as-usual left-of-center politics. A typical rundown of degrowth policies looks like a wish list from the Democratic Socialists of America: health care for all, universal basic income, a smaller military, mutual aid, better public transportation, decolonization, and so on. Adherents reject the view that degrowth would require some authoritarian power to impose it, but have yet to articulate a political plan besides changing one mind at a time.

“At bottom it’s not actually an evidence-based agenda,” Ted Nordhaus, the founder and executive director of the Breakthrough Institute and self-described “eco-modernist,” told me. “It’s sort of a worldview and a vibe.”

And yet, for many, the vibe hits. Degrowth captures a core truth of the fight against climate change: What we’re doing is not enough and might even be making things worse. Degrowth might fail too, but in the eyes of its supporters, at least it’s directionally correct. It’s the protest vote of climate activism.

While in D.C., Saito co-headlined a workshop with a few dozen students at Georgetown, where they discussed degrowth. The group was mostly in favor, according to two students who attended. Fiona Naughton, a rising sophomore who studies international labor policy, told me she and many of her peers find Saito’s ideas inspiring. “A lot of us have felt such immense climate anxiety and considered whether or not we should have children,” she said. “Degrowth gives us hope for a future that we haven’t felt in a long, long time.”

I also followed up with Tianle Zhang, the protester who’d taken a selfie with Saito at the Columbia rally, and asked him about how he’d discovered Saito’s work. Zhang said that as a kid in Indiana, he’d watched the news in horror as oil gushed into the Gulf of Mexico for months after the Deepwater Horizon rig exploded. In college, he’d sensed a gap between the immensity of the problem of climate change and the attempts to address it. Saito was one of the few scholars he found who was trying to connect thinking about the environment with a broader theoretical critique of capitalism and society.

Zhang said he was also deeply influenced by Paul Schrader’s 2017 film, First Reformed. The film stars Ethan Hawke as a troubled priest who descends so far into climate despair that he considers committing an act of terrorism. “For me, it was showing the failures of conventional morality to handle the issue of climate,” Zhang said.

[From the January/February 2023 issue: Why the age of American progress ended]

Degrowth’s appeal might be similar: not political, not even economic, but moral. In the climactic final scene of First Reformed, Hawke’s character wraps himself in barbed wire as he prepares to possibly do something horrifying and futile. This seems like a fitting metaphor for not only Saito’s proposals—Saito acknowledges that degrowth would require pain—but also their psychological appeal. We have been bad, and we must atone.

Beyond its stark moral claims, the very fact of degrowth’s unreasonableness gives it weight. Degrowth advocates have called it a “missile word,” designed to provoke. There’s a reason we’re talking about degrowth and not the “steady-state economy,” which environmentalists have been pushing for decades. As the prominent degrowth thinker Jason Hickel has written, the term itself upends conventional wisdom: “It is only negative if we start from the assumption that more growth is good and desirable.” To this way of thinking, the inconceivability of degrowth only highlights how trapped we are in the growth-fetishist mindset.

At the end of our dinner, Saito told me he’s working on his next book, about the role of government when it comes to implementing degrowth. “The state has to intervene, but how can we make a democratic transition?” he asked rhetorically. I asked if he had an answer. He said, “Not yet.”

Drought killer: California storms fill reservoirs, build up Sierra snowpack

It's been the wettest November on record for several Southern California cities. But experts say that despite the auspicious start, it's still too soon to say how the rest of California's traditional rainy season will shape up.

A string of early season storms that drenched Californians last week lifted much of the state out of drought and significantly reduced the risk of wildfires, experts say.It’s been the wettest November on record for Southland cities such as Van Nuys and San Luis Obispo. Santa Barbara has received an eye-popping 9.5 inches of rain since Oct. 1, marking the city’s wettest start to the water year on record. And overall the state is sitting at 186% of its average rain so far this water year, according to the Department of Water Resources.But experts say that despite the auspicious start, it’s still too soon to say how the rest of California’s traditional rainy season will shape up.“The overall impact on our water supply is TBD [to be determined] is the best way to put it,” said Jeff Mount, senior fellow at the Public Policy Institute of California’s Water Policy Center. “We haven’t even really gotten into the wet season yet.”California receives the vast bulk of its rain and snow between December and March, trapping the runoff in its reservoirs to mete out during the hot, dry seasons that follow. Lights from bumper-to-bumper traffic along Aliso Street reflect off the federal courthouse in Los Angeles on a rainy night. (Robert Gauthier/Los Angeles Times) Those major reservoirs are now filled to 100% to 145% of average for this date. That’s not just from the recent storms — early season rains tend to soak mostly into the parched ground — but also because California is building on three prior wet winters, state climatologist Michael Anderson said.A record-breaking wet 2022-23 winter ended the state’s driest three-year period on record. That was followed by two years that were wetter than average for Northern California but drier than average for the southern half, amounting to roughly average precipitation statewide.According to the latest U.S. Drought Monitor report, issued last week before the last of the recent storms had fully soaked the state, more than 70% of California was drought-free, compared with 49% a week before. Nearly 47% of Los Angeles County emerged from moderate drought, with the other portions improving to abnormally dry, the map shows. Abnormally dry conditions also ended in Ventura, Santa Barbara, San Luis Obispo and much of Kern counties, along with portions of Central California, according to the map. In the far southern and southeastern reaches of the state, conditions improved but still range from abnormally dry to moderate drought, the map shows.The early season storms will play an important role in priming watersheds for the rest of the winter, experts said. By soaking soils, they’ll enable future rainstorms to more easily run off into reservoirs and snow to accumulate in the Sierra Nevada.“Building the snowpack on hydrated watersheds will help us avoid losing potential spring runoff to dry soils later in the season,” Anderson wrote in an email.Snowpack is crucial to sustaining California through its hot, dry seasons because it runs down into waterways as it melts, topping off the reservoirs and providing at least 30% of the state’s water supply, said Andrew Schwartz, director of UC Berkeley’s Central Sierra Snow Lab.The research station at Donner Pass has recorded 22 inches of snow. Although that’s about 89% of normal for this date, warmer temperatures mean that much of it has already melted, Schwartz said. The snow water equivalent, which measures how much water the snow would produce if it were to melt, now stands at 50%, he said.“That’s really something that tells the tale, so far, of this season,” he said. “We’ve had plenty of rain across the Sierra, but not as much snowfall as we would ordinarily hope for up to this point.”This dynamic has become increasingly common with climate change, Schwartz said. Snow is often developing later in the season and melting earlier, and more precipitation is falling as rain, he said. Because reservoirs need to leave some room in the winter for flood mitigation, they aren’t always able to capture all this ill-timed runoff, he said.And the earlier the snow melts, the more time plants and soils have to dry out in the summer heat, priming the landscape for large wildfires, Schwartz said. Although Northern California has been spared massive fires for the last few seasons, Schwartz fears that luck could run out if the region doesn’t receive at least an average amount snow this year.For now, long-range forecasts are calling for equal chances of wet and dry conditions this winter, Mount said. What happens in the next few months will be key. California depends on just a few strong atmospheric river storms to provide moisture; as little as five to seven can end up being responsible for more than half of the year’s water supply, he said.“We’re living on the edge all the time,” he said. “A handful of storms make up the difference of whether we have a dry year or a wet year.”Although the state’s drought picture has improved for the moment, scientists caution that conditions across the West are trending hotter and drier because of the burning of fossil fuels and resultant climate change. In addition to importing water from Northern California via the Sacramento-San Joaquin River Delta, Southern California relies on water from the Colorado River. That waterway continues to be in shortage, with its largest reservoir only about one-third full.What’s more, research has shown that as the planet has warmed, the atmosphere has become thirstier, sucking more moisture from plants and soils and ensuring that dry years are drier. At the same time, there’s healthy debate over whether the same phenomenon is also making wet periods wetter, as warmer air can hold more moisture, potentially supercharging storms.As a result, swings between wet and dry on a year-to-year basis — and even within a year — seem to be getting bigger in California and elsewhere, Mount said. That increase in uncertainty has made managing water supplies more difficult overall, he said.Still, because of its climate, California has plenty of experience dealing with such extremes, said Jay Lund, professor emeritus of civil and environmental engineering at UC Davis.“We always have to be preparing for floods and preparing for drought, no matter how wet or dry it is.”Staff writer Ian James contributed to this report.

Indigenous People Reflect On What It Meant To Participate In COP30 Climate Talks

Many who attended the UN summit in the Amazon liked the solidarity and small wins, but some felt the talks fell short on representation and true climate action.

BELEM, Brazil (AP) — Indigenous people filled the streets, paddled the waterways and protested at the heart of the venue to make their voices heard during the United Nations climate talks that were supposed to give them a voice like never before at the annual conference.As the talks, called COP30, concluded Saturday in Belem, Brazil, Indigenous people reflected on what the conference meant to them and whether they were heard.Brazilian leaders had high hopes that the summit, taking place in the Amazon, would empower the people who inhabit the land and protect the biodiversity of the world’s largest rainforest, which helps stave off climate change as its trees absorb carbon pollution that heats the planet.Many Indigenous people who attended the talks felt strengthened by the solidarity with tribes from other countries and some appreciated small wins in the final outcome. But for many, the talks fell short on representation, ambition and true action on climate issues affecting Indigenous people.“This was a COP where we were visible but not empowered,” said Thalia Yarina Cachimuel, a Kichwa-Otavalo member of A Wisdom Keepers Delegation, a group of Indigenous people from around the world.Some language wins but nothing on fossil fuelsFrom left: Taily Terena, Gustavo Ulcue Campo, Bina Laprem and Sarah Olsvig attend an Indigenous peoples forum on climate change at the COP30 UN Climate Summit, on Nov. 21, 2025, in Belem, Brazil.Andre Penner via Associated PressThe first paragraph of the main political text acknowledges “the rights of Indigenous Peoples, as well as their land rights and traditional knowledge.”Taily Terena, an Indigenous woman from the Terena nation in Brazil, said she was happy because the text for the first time mentioned those rights explicitly.But Mindahi Bastida, an Otomí-Toltec member of A Wisdom Keepers Delegation, said countries should have pushed harder for agreements on how to phase out fuels like oil, gas and coal “and not to see nature as merchandise, but to see it as sacred.”Several nations pushed for a road map to curtail use of fossil fuels, which when burned release greenhouse gases that warm the planet. Saturday’s final decision left out any mention of fossil fuels, leaving many countries disappointed.Brazil also launched a financial mechanism that countries could donate to, which was supposed to help incentivize nations with lots of forest to keep those ecosystems intact.Although the initiative received monetary pledges from a few countries, the project and the idea of creating a market for carbon are false solutions that “don’t stop pollution, they just move it around,” said Jacob Johns, a Wisdom Keeper of the Akimel O’Otham and Hopi nations.“They hand corporations a license to keep drilling, keep burning, keep destroying, so long as they can point to an offset written on paper. It’s the same colonial logic dressed up as climate policy,” Johns said.Concerns over tokenismBrazil Indigenous Peoples Minister Sonia Guajajara (R) poses for a selfie while walking through the COP30 UN Climate Summit venue, on Nov. 17, 2025, in Belem, Brazil.Andre Penner via Associated PressFrom the beginning of the conference, some Indigenous attendees were concerned visibility isn’t the same as true power. At the end, that sentiment lingered.“What we have seen at this COP is a focus on symbolic presence rather than enabling the full and effective participation of Indigenous Peoples,” Sara Olsvig, chair of the Inuit Circumpolar Council, wrote in a message after the conference concluded.Edson Krenak, Brazil manager for Indigenous rights group Cultural Survival and member of the Krenak people, didn’t think negotiators did enough to visit forests or understand the communities living there. He also didn’t believe the 900 Indigenous people given access to the main venue was enough.Sônia Guajajara, Brazil’s minister of Indigenous peoples, who is Indigenous herself, framed the convention differently.“It is undeniable that this is the largest and best COP in terms of Indigenous participation and protagonism,” she said.Protests showed power of Indigenous solidarityIndigenous leader and climate activist Txai Surui (R) shouts slogans while leaving a plenary session during the COP30 UN Climate Change Conference in Belem, Brazil, on Nov. 21, 2025. Pablo Porciuncula/AFP via Getty ImagesWhile the decisions by delegates left some Indigenous attendees feeling dismissed, many said they felt empowered by participating in demonstrations outside the venue.When the summit began on Nov. 10, Paulo André Paz de Lima, an Amazonian Indigenous leader, thought his tribe and others didn’t have access to COP30. During the first week, he and a group of demonstrators broke through the barrier to get inside the venue. Authorities quickly intervened and stopped their advancement.De Lima said that act helped Indigenous people amplify their voices.“After breaking the barrier, we were able to enter COP, get into the Blue Zone and express our needs,” he said, referring to the official negotiation area. “We got closer (to the negotiations), got more visibility.”The meaning of protest at this COP wasn’t just to get the attention of non-Indigenous people, it also was intended as a way for Indigenous people to commune with each other.On the final night before an agreement was reached, a small group with banners walked inside the venue, protesting instances of violence and environmental destruction from the recent killing of a Guarani youth on his own territory to the proposed Prince Rupert Gas Transmission Project in Canada.“We have to come together to show up, you know? Because they need to hear us,” Leandro Karaí of the Guarani people of South America said of the solidarity among Indigenous groups. “When we’re together with others, we’re stronger.“They sang to the steady beat of a drum, locked arms in a line and marched down the long hall of the COP venue to the exit, breaking the silence in the corridors as negotiators remained deadlocked inside.Then they emerged, voices raised, under a yellow sky.

This Pig’s Bacon Was Delicious—and She’s Alive and Well

This story was originally published by Grist and is reproduced here as part of the Climate Desk collaboration. I’m eating Dawn the Yorkshire pig and she’s quite tasty. But don’t worry. She’s doing perfectly fine, traipsing around a sanctuary in upstate New York. Word is that she appreciates belly rubs and sunshine. I’m in San Francisco, at an Italian joint just south of Golden Gate Park, enjoying meatballs and bacon not made of meat in the traditional sense but of plants mixed with “cultivated” pork fat. Dawn, you see, donated a small sample of fat, which a company called Mission Barns got to proliferate in devices called bioreactors by providing nutrients like carbohydrates, amino acids, and vitamins—essentially replicating the conditions in her body. Because so much of the flavor of pork and other meats comes from the animal’s fat, Mission Barns can create products like sausages and salami with plants but make them taste darn near like sausages and salami.  I’ve been struggling to describe the experience, because cultivated meat short-circuits my brain—my mouth thinks I’m eating a real pork meatball, but my brain knows that it’s fundamentally different and that Dawn (pictured above) didn’t have to die for it. This is the best I’ve come up with: It’s Diet Meat. Just as Diet Coke is an approximation of the real thing, so too are cultivated meatballs. They simply taste a bit less meaty, at least to my tongue. Which is understandable, as the only animal product in this food is the bioreactor-grown fat. Cultivated pork is the newest entrant in the effort to rethink meat. For years, plant-based offerings have been mimicking burgers, chicken, and fish with ever-more convincing blends of proteins and fats. Mission Barns is one of a handful of startups taking the next step: growing real animal fat outside the animal, then marrying it with plants to create hybrids that look, cook, and taste more like what consumers have always eaten, easing the environmental and ethical costs of industrial livestock. The company says it’s starting with pork because it’s a large market and products like bacon are fat-rich, but its technology is “cell-agnostic,” meaning it could create beef and chicken, too. Lab-grown meat ballsMatt Simon Honestly, Mission Barns’ creations taste great, in part because they’re “unstructured,” in the parlance of the industry. A pork loin is a complicated tangle of fat, muscle cells, and connective tissues that is very difficult and expensive to replicate, but a meatball, salami, or sausage incorporates other ingredients. That allows Mission Barns to experiment with what plant to use as a base, and then add spices to accentuate the flavors. It’s a technology that they can iterate, basically, crafting ever-better meats by toying with ingredients in different ratios.  So the bacon I ate, for instance, had a nice applewood smoke to it. The meatballs had the springiness you’d expect. During a later visit to Mission Barns’ headquarters across town, I got to try two prototypes of its salami as well—both were spiced like you’d expect but less elastic, so they chewed a bit more easily than what you’d find on a charcuterie board. (The sensation of food in the mouth is known in the industry as “mouthfeel,” and nailing it is essential to the success of alt meats.) The salami slices even left grease stains on the paper they were served on—Dawn’s own little mark on the world. I was one of the first people to purchase a cultivated pork product. While Mission Barns has so far only sold its products at that Italian restaurant and, for a limited time, at a grocery store in Berkeley—$13.99 for a pack of eight meatballs, similar to higher-end products from organic and regenerative farms—it is fixing to scale up production and sell the technology to other companies to produce more cultivated foods. (It is assessing how big the bioreactors will have to be to reach price parity with traditional meat products.) The idea is to provide an alternative to animal agriculture, which uses a whole lot of land, water, and energy to raise creatures and ship their flesh around the world. Livestock are responsible for between 10 and 20 percent of humanity’s greenhouse gas emissions—depending on who’s estimating it—and that’s to say nothing of the cruelty involved in keeping pigs and chickens and cows in unsavory, occasionally inhumane, conditions. “I also love the idea of taking their pork fat and putting it in a beef burger.” Getting animal cells to grow outside of an animal, though, ain’t easy. For one, if cells don’t have anything to attach to, they die. So Mission Barns’ cultivator uses a spongelike structure, full of nooks and crannies that provides lots of surface area for the cells to grow. “We have our media, which is just the nutrient solution that we give to these cells,” said Saam Shahrokhi, chief technology officer at Mission Barns. “We’re essentially recapitulating all of the environmental cues that make cells inside the body grow fat, [but] outside the body.” While Dawn’s fat is that of a Yorkshire pig, Shahrokhi said they could easily produce fat from other breeds like the Mangalitsa, known as the Kobe beef of pork. (In June, the company won approval from the US Department of Agriculture to bring its cultivated fat to market.) Fat in hand, Mission Barns can mix it with plant proteins. If you’re familiar with Impossible Foods, it uses soy to replicate the feel and look of ground beef and adds soy leghemoglobin, which is similar to the heme that gives meat its meaty flavor. Depending on the flavor and texture it’s trying to copy, Mission Bay uses pea protein for the meatballs and sausages, wheat for the bacon, and fava beans for the salami. “The plant-based meat industry has done pretty well with texture,” said Bianca Le, head of special projects at Mission Barns. “I think what they’re really missing is flavor and juiciness, which obviously is where the fat comes in.” But the fat is just the beginning. Mission Barns’ offerings not only have to taste good, but also can’t have an off-putting smell when they’re coming out of the package and when they’re cooking. The designers have to dial in the pH, which could degrade the proteins if not balanced. How the products behave on the stove or in the oven has to be familiar, too. “If someone has to relearn how to cook a piece of bacon or a meatball, then it’s never going to work,” said Zach Tyndall, the product development and culinary manager at Mission Barns. Lab-grown salamiMatt Simon When I pick up that piece of salami, it has to feel like the real thing, in more ways than one. Indeed, it’s greasy in the hand and has that tang of cured meat. It’s even been through a dry-aging process to reduce its moisture. “We treat this like we would a conventional piece of salami,” Tyndall said.  Cultivated meat companies may also go more unconventional. “I also love the idea of taking their pork fat and putting it in a beef burger—what would happen if you did that?” said Barb Stuckey, chief new product strategy officer at Mattson, a food developer that has worked with many cultivated meat companies. “Mixing species, it’s not something we typically do. But with this technology, we can.”  Of course, in this new frontier of food, the big question is: Who exactly is this for? Would a vegetarian or vegan eat cultured pork fat if it’s divorced from the cruelty of factory farming? Would meat-eaters be willing to give up the real thing for a facsimile? Mission Barns’ market research, Le said, found that its early adopters are actually flexitarians—people who eat mostly plant-based but partake in the occasional animal product. But Le adds that their first limited sale to the public in Berkeley included some people who called themselves vegetarians and vegans.  There’s also the matter of quantifying how much of an environmental improvement cultivated fat might offer over industrial pork production. If scaled up, one benefit of cultivated food might be that companies can produce the stuff in more places—that is, instead of sprawling pig farms and slaughterhouses being relegated to rural areas, bioreactors could be run in cities, cutting down on the costs and emissions associated with shipping. Still, those factories would need energy to grow fat cells, though they could be run on renewable electricity. “We modeled our process at the large commercial scale, and then compared it to U.S. bacon production,” Le said. (The company would not offer specific details, saying it is in the process of patenting its technique.) “And we found that with renewable energy, we do significantly better in terms of greenhouse gas emissions.” Whether or not consumers bite, though, remains to be seen. The market for meat alternatives in the US has majorly softened of late: Beyond Meat, which makes plant-based products like burgers and sausages, has seen revenues drop significantly, in part because of consumers’ turn away from processed foods. But by licensing its technology elsewhere, Mission Barns’ strategy is to break into new markets beyond the United States. The challenges of cultivated meat go beyond the engineering once you get to the messaging and branding—telegraphing to consumers that they’re buying something that may in fact be partially meat. “When you buy chicken, you get 100 percent chicken,” Stuckey said. “I think a lot of people go into cultivated meat thinking what’s going to come onto the market is 100 percent cultivated chicken, and it’s not going to be that. It’s going to be something else.”  Regardless of the trajectory of cultivated fat products, Dawn will continue mingling with llamas, soaking up the sunshine, and getting belly rubs in upstate New York—even as she makes plants taste more like pork. 

Why is climate action stalling, not ramping up as Earth gets hotter?

As the impact of global warming becomes more obvious, you might expect countries to step up climate action and preparation, but we’re seeing the opposite happen

Climate campaigners march on the sidelines of the COP30 summit in Belém, BrazilPABLO PORCIUNCULA/AFP via Getty Images Ten years on from the Paris Agreement, we should be seeing a massive ratcheting up of climate action. Instead, the past four years have seen almost no progress – including at the latest COP summit, which failed to take any meaningful steps towards phasing out fossil fuels or ending deforestation. What’s going on? I don’t know the answer. But I’m starting to fear that rather than responding more rationally as the world heats up and the impacts get ever more serious, our responses are becoming more irrational. If that is the case, climate impacts are going to be much worse than they would otherwise be, and the prospect of a decline in our global civilisation seems more plausible than I have long thought. Let’s start by going back to the Paris Agreement of 2015. The whole idea of an international climate agreement under which every country sets its own targets for limiting greenhouse emissions seemed ludicrous to me. As did the idea of setting an “aspirational” target of 1.5°C that was wildly disconnected from what countries were planning to do. Supporters claimed this would be solved by a “ratchet mechanism”, under which countries would progressively increase their targets. I wasn’t convinced. I came away from Paris regarding it as a gigantic greenwashing exercise. My expectation was that it would have little immediate impact, but as the effects of warming became more obvious, action would start to ramp up. In other words, reason would eventually prevail. So far, the opposite has happened. In the lead-up to Paris, in October 2015, the Climate Action Tracker project estimated that the world was heading for warming of around 3.6°C by 2100, based on current policies and action. By 2021, that estimate had been revised down to around 2.6°C. That’s a massive improvement − it seemed Paris was working. But the latest Climate Action Tracker report ahead of the COP30 summit makes for grim reading. For the fourth year in a row there has been “little to no measurable progress”. “Global progress is stalling,” the report says. “While a handful of countries are making genuine progress, their efforts are counterbalanced by others delaying, or rolling back climate policies.” In fact, an astonishing 95 per cent of countries missed this year’s deadline for updating their targets under that ratchet mechanism. Yes, renewable energy generation is growing much faster than predicted. But this is being counterbalanced by the huge sums being poured into fossil fuels. Cheap solar alone isn’t going to save us. For one thing, negative feedback effects kick in: the more solar there is, the less profitable it is to install more. For another, generating green electricity is the easy part – we’re not making nearly enough progress on the hard things, such as farming, flying and steel-making. What’s more, the problem isn’t just the failure to slash emissions. We’re not preparing to cope with what’s coming, either. We’re still building cities on sinking land next to rising seas. “Adaptation progress is either too slow, has stalled, or is heading in the wrong direction,” said an April report by the UK’s Climate Change Committee – and the picture is similar elsewhere. The big question is why climate action is stalling instead of ramping up further. In some countries, it’s obviously due to the election of politicians who don’t see climate change as a priority or unashamedly deny it, as reflected by the US withdrawing from the Paris Agreement. Even governments that say climate is a priority are doing less, however, seemingly on the basis that there are more urgent issues to deal with such as the cost of living crisis. Yet the cost of living crisis is in part a climate crisis, with extreme weather helping drive up food prices. As warming continues, the impact on food and the wider economy is only going to become more serious. Are we going to get to the point where governments say they can’t act on climate change because of the costs of dealing with major cities being inundated by rising seas? Are people’s fears about the state of the world going to make them keep voting for climate deniers despite pollsters telling us that most people worldwide want more climate action? The idea that that growing evidence will persuade leaders to come to their senses is looking ever more naive. We are, after all, in a strange multiverse where the US Centers for Disease Control is promoting antivax nonsense even as the country is about to lose its measles-free status, and where some politicians promote the idea that hurricanes were due to weather manipulation. After year after year of record-smashing heat, it’s never been more obvious that climate change is real and really bad. But perhaps that’s the problem. The philosopher Martha Nussbaum has argued that fear is a tremendously negative force that makes people abandon rationality and focus on their immediate welfare rather than the long-term good. And there is some evidence that environmental stresses make people behave irrationally. People tend to leap straight from “things are bad” to “we’re all doomed”. No, we aren’t doomed. But the longer it takes for reason to prevail, the worse the outcome will be. Maybe what we’re seeing is just a blip related to the pandemic fallout and Russia’s war on Ukraine − or maybe there’s something more worrying happening.

How to make data centers less thirsty

There’s a way to reduce both the climate and water harms of data centers: build them in places with lots of wind and solar energy.

Data centers are notoriously thirsty. Researchers at Lawrence Berkeley National Laboratory have found that, in 2023, the facilities consumed roughly 17 billion gallons of water for their operations in the U.S. alone. But that’s only a small part of the picture: A much, much larger share of data center water-intensity is indirect, a byproduct of the facilities’ enormous appetites for energy. That’s because most power plants themselves require huge amounts of water to operate. This off-site, indirect water consumption amounted to a whopping 211 billion gallons in the Berkeley lab’s 2023 tally — well over 10 times the direct on-site usage. As Silicon Valley continues to pour hundreds of billions of dollars into artificial intelligence and demand for data centers grows, these water needs are only going to grow in tandem.  However, new research from Cornell University shows that there’s a way to mitigate both the climate and water footprints of these facilities: build them in places with lots of wind and solar energy. “Location really matters,” said Fengqi You, an energy systems engineering professor at Cornell and co-author of the new study. Where companies choose to locate their data centers could alter their combined environmental footprints by a factor of up to 100. In the course of their operations, data centers use water as a coolant. Energy-hungry servers generate substantial heat, and water circulates through cooling systems to prevent the equipment from overheating and breaking down. But substantial amounts of water are also used indirectly through the generation of electricity to run the facilities. Thermoelectric power plants, regardless of whether they use coal, gas, or nuclear material, use that fuel to generate heat that converts water into steam, which is then used to spin a turbine and generate electricity. And since hydroelectric plants typically store large volumes of water in reservoirs behind dams, there is water loss there as well, as water continually evaporates from the surface of reservoirs. All told, water use during power generation can be responsible for more than 70 percent of a data center’s total water consumption, according to the new Cornell research. “That’s why the electricity power grid mix is very critical,” said You.  You and his co-authors examined the energy and water use of data centers across the country to project where future investments should be made to reduce environmental impacts. The study assumes that the data center boom, which is being fueled by staggering levels of investment in artificial intelligence, is unlikely to slow down anytime soon. Against that backdrop, the question the study then poses is: Where in the country is the most environmentally sustainable place to build a data center? The researchers considered both the direct and indirect uses of energy and water as a result of building a data center in a specific location. The most promising region they identified might turn heads: bone-dry West Texas. But because the region is sparsely populated, has groundwater that can be drawn on for use as a coolant, and produces ample wind energy, it scored highest on both energy and water stress metrics. In fact, the grid-related water footprint in West Texas is among the lowest in the country, thanks to the large amount of wind energy produced, according to the study. “From an energy and water efficiency perspective, the states that have enough dry renewables will be the best choice,” said You, adding that Montana, Nebraska, and South Dakota all appear to be prime locations for future AI servers, alongside the Lone Star State. Conversely, most parts of the Pacific Northwest didn’t score as well because of the region’s reliance on hydropower. Although the cost of electricity is low in the area, the associated loss of water through power generation means that building more data centers is likely to have a substantially larger water footprint than it would in other parts of the country. Another recent study from researchers at Purdue University came to a similar conclusion. They looked at the availability of water across the country and mapped out how that might change over time, particularly as climate change makes some regions hotter and drier. The researchers also examined the water impact of existing Google data centers and found that the majority were located in areas with low water stress. “Companies absolutely take the environment into consideration in their decisions — not just the economic factor,” said Yi Ding, one of the authors of the paper and an electrical and computer engineering professor at Purdue. “We infer that Google already somewhat considered water stress because they put most of the data centers in low-stress regions.” Texas already has more than 400 data centers located in the state, second only to Virginia. The state’s grid infrastructure, potential for renewables, and availability of cheap land has made it an attractive proposition for tech companies. But the other states identified by the Cornell study as having a small environmental footprint — Nebraska, South Dakota, and Montana — have just 70 or so data centers combined, out of more than at least 4,200 nationally. That’s because a number of other factors, such as the policy environment and infrastructure considerations, are deterring companies from building new facilities there. But if those states geared their policymaking toward attracting data centers, it could make a difference, You said.
