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.”

Neil Frank, Former Hurricane Center Chief Who Improved Public Outreach on Storms, Has Died

Neil Frank, a former head of the National Hurricane Center credited with working to increase the country’s readiness for major storms, has died

Neil Frank, a former head of the National Hurricane Center credited with increasing the country's readiness for major storms, died Wednesday. He was 94.Frank led the hurricane center from 1974 to 1987, the longest-serving director in its history.“He gets tremendous credit for the being the first one to go out of his way and reach out and make the connection between the National Hurricane Center and the emergency managers,” said meteorologist Max Mayfield, who served as the hurricane center's director from 2000-2007. “He taught me that it’s not all about the forecast,” Mayfield said. “A perfect forecast is no good if people don’t take immediate action.”Frank’s son, Ron Frank, said in a Facebook post that his father died at home a few days after going into hospice care.KHOU-TV in Houston, where Frank spent two decades as chief meteorologist after leaving the hurricane center, first reported his death. The station referred an Associated Press call for comment to CBS, whose spokeswoman declined comment but directed the AP to Ron Frank’s post.When Frank started at the National Hurricane Center, advances with weather satellites were helping forecasters to better predict the location and direction of a storm. Frank worked to make that information more accessible to residents in hurricane-vulnerable areas, said Mayfield. He also regularly appeared on television to give updates on storms and advice on staying safe.“He was so passionate and you could just feel his enthusiasm but also sense of warning — that he wanted people to take action,” Mayfield said. “He was very animated, spoke with his hands a lot. And if you’d play it on fast-forward, he’d look like a juggler sometimes.”Frank was skeptical that human actions, such as the burning of oil, gas and coal, cause climate change, Mayfield said. In a video posted to YouTube titled “Is Climate Change Real?” he instead attributed warming to the planet’s natural and cyclical weather patterns. Scientists today overwhelmingly agree that burning of fossil fuels is the primary driver of planet-warming emissions that are causing more frequent, costly and deadly extreme weather around the world.The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.

Seven books to help you work through the climate anxiety you developed in 2025

With the holiday travel season ramping up, a good book is a must-have for airport delays or to give as the perfect gift.

With the holiday travel season ramping up, a good book is a must-have for airport delays or to give as the perfect gift.Journalists from Bloomberg Green picked seven climate and environmental books they loved despite their weighty content. A few were positively uplifting. Here are our recommendations.Fiction“What We Can Know” by Ian McEwanIt’s 2119, decades after the Derangement (cascading climate catastrophes), the Inundation (a global tsunami triggered by a Russian nuclear bomb) and artificial intelligence-launched wars have halved the world’s population. The U.S. is no more and the U.K. is an impoverished archipelago of tiny islands where scholar Tom Metcalfe embarks on an obsessive quest to find the only copy of a renowned 21st century poem that was never published.The famous author of the ode to now-vanished English landscapes recited it once at a dinner party in 2014 as a gift to his wife, but its words remain lost to time. Metcalfe believes access to the previously hidden digital lives of the poet and his circle will lead him to the manuscript. He knows where to start his search: Thanks to Nigeria — the 22nd century’s superpower — the historical internet has been decrypted and archived, including every personal email, text, photo and video.The truth, though, lies elsewhere. It’s a richly told tale of our deranged present — and where it may lead without course correction. — Todd Woody“Greenwood” by Michael ChristieThis likewise dystopian novel begins in 2038 with Jacinda Greenwood, a dendrologist turned tour guide for the ultra-wealthy, working in one of the world’s last remaining forests. But the novel zig-zags back to 1934 and the beginnings of a timber empire that divided her family for generations.For more than a century, the Greenwoods’ lives and fates were entwined with the trees they fought to exploit or protect. The novel explores themes of ancestral sin and atonement against the backdrop of the forests, which stand as silent witnesses to human crimes enacted on a global scale. — Danielle Bochove“Barkskins” by Annie ProulxAnother multigenerational saga, spanning more than three centuries and 700 pages, this 2016 novel by a Pulitzer Prize-winning author tracks the deforestation of the New World over 300 years, beginning in the 17th century.Following the descendants of two immigrants to what will become modern-day Quebec, the story takes the reader on a global voyage, crisscrossing North America, visiting the Amsterdam coffee houses that served as hubs for the Dutch mercantile empire and following new trade routes from China to New Zealand. Along the way, it chronicles the exploitation of the forests, the impact on Indigenous communities and the lasting legacy of colonialism.With a vast cast of characters, the novel is at times unwieldy. But the staggering descriptions of Old World forests and the incredible human effort required to destroy them linger long after the saga concludes. —Danielle BochoveNonfiction“The Joyful Environmentalist: How to Practise Without Preaching” by Isabel LosadaIt is hard for a committed environmentalist to feel cheerful these days. But Isabel Losada’s book encourages readers to undertake a seemingly impossible mission: finding delight in navigating the absurd situations that committed environmentalists inevitably face, rather than succumbing to frustration.Those delights can be as simple as looking up eco-friendly homemade shampoo formulas on Instagram or crushing a bucket of berries for seed collection to help restore native plants.The book itself is an enjoyable read. With vivid details and a dose of British humor, Losada relays her failed attempt to have lunch at a Whole Foods store without using its disposable plastic cutlery. (The solution? Bring your own metal fork.) To be sure, some advice in her book isn’t realistic for everyone. But there are plenty of practical tips, such as deleting old and unwanted emails to help reduce the energy usage of data centers that store them. This book is an important reminder that you can protect the environment joyfully.— Coco Liu“Breakneck: China’s Quest to Engineer the Future” by Dan WangChina’s President Xi Jinping is a trained engineer, and so are many members of the country’s top leadership. Dan Wang writes about how that training shows up in the country’s relentless push to build, build and build. That includes a clean tech industry that leads the world in almost every conceivable category, though Wang explores other domains as well.Born in China, Wang grew up in Canada and studied in the U.S. before going back to live in his native country from 2017 to 2023. That background helps his analysis land with more gravity in 2025, as the U.S. and China face off in a battle of fossil fuels versus clean tech. — Akshat Rathi“Entangled Life: How Fungi Make Our Worlds, Change Our Minds and Shape Our Futures” by Merlin SheldrakeA JP Morgan banker might seem an unlikely character in a book about fungi. But R. Gordon Wasson, who popularized the main compound found in “magic mushrooms” with a 1957 article in Life magazine, is only one of the delightful surprises in Merlin Sheldrake’s offbeat book. The author’s dedication to telling the tale of fungi includes literally getting his hands dirty, unearthing complex underground fungal networks, and engaging in self-experimentation by participating in a scientific study of the effects of LSD on the brain. The result is a book that reveals the complexity and interdependency of life on Earth, and the role we play in it.“We humans became as clever as we are, so the argument goes, because we were entangled within a demanding flurry of interaction,” Sheldrake writes. Fungi, a lifeform that depends on its interrelatedness with everything else, might have more in common with us than we realize. — Olivia Rudgard“Toms River: A Story of Science and Salvation” by Dan FaginWhen chemical manufacturer Ciba arrived in Toms River, N.J., in 1952, the company’s new plant seemed like the economic engine the sleepy coastal community dependent on fishing and tourism had always needed. But the plant soon began quietly dumping millions of gallons of chemical-laced waste into the town’s eponymous river and surrounding woods. That started a legacy of toxic pollution that left families asking whether the waste was the cause of unusually high rates of childhood cancer in the area.This Pulitzer Prize-winning masterpiece of environmental journalism reads like a thriller, albeit with devastating real-world fallout. It also shows how companies can reinvent themselves: I was startled to learn that Ciba, later known as Ciba-Geigy, merged with another company in 1996 to become the pharmaceutical company Novartis. At a time when there’s been a push to relocate manufacturing from abroad back to the U.S., this is a worthy examination of the hidden costs that can accompany industrial growth. — Emma CourtBochove, Woody, Liu, Court, Rudgard and Rathi write for Bloomberg.

Google is betting on carbon capture tech to lower data center emissions. Here’s how it works

As AI data centers spring up across the country, their energy demand and resulting greenhouse gas emissions are raising concerns. With servers and energy-intensive cooling systems constantly running, these buildings can use anywhere from a few megawatts of power for a small data center to more than 100 megawatts for a hyperscale data center. To put that in perspective, the average large natural gas power plant built in the U.S. generates less than 1,000 megawatts. When the power for these data centers comes from fossil fuels, they can become major sources of climate-warming emissions in the atmosphere—unless the power plants capture their greenhouse gases first and then lock them away. Google recently entered into a unique corporate power purchase agreement to support the construction of a natural gas power plant in Illinois designed to do exactly that through carbon capture and storage. So how does carbon capture and storage, or CCS, work for a project like this? I am an engineer who wrote a 2024 book about various types of carbon storage. Here’s the short version of what you need to know. How CCS works When fossil fuels are burned to generate electricity, they release carbon dioxide, a powerful greenhouse gas that remains in the atmosphere for centuries. As these gases accumulate in the atmosphere, they act like a blanket, holding heat close to the Earth’s surface. Too high of a concentration heats up the Earth too much, setting off climate changes, including worsening heat waves, rising sea levels, and intensifying storms. Carbon capture and storage involves capturing carbon dioxide from power plants, industrial processes, or even directly from the air and then transporting it, often through pipelines, to sites where it can be safely injected underground for permanent storage. The carbon dioxide might be transported as a supercritical gas—which is right at the phase change from liquid to gas and has the properties of both—or dissolved in a liquid. Once injected deep underground, the carbon dioxide can become permanently trapped in the geologic structure, dissolve in brine, or become mineralized, turning it to rock. The goal of carbon storage is to ensure that carbon dioxide can be kept out of the atmosphere for a long time. Types of underground carbon storage There are several options for storing carbon dioxide underground. Depleted oil and natural gas reservoirs have plentiful storage space and the added benefit that most are already mapped and their limits understood. They already held hydrocarbons in place for millions of years. Carbon dioxide can also be injected into working oil or gas reservoirs to push out more of those fossil fuels while leaving most of the carbon dioxide behind. This method, known as enhanced oil and gas recovery, is the most common one used by carbon capture and storage projects in the U.S. today, and one reason CCS draws complaints from environmental groups. Volcanic basalt rock and carbonate formations are considered good candidates for safe and long-term geological storage because they contain calcium and magnesium ions that interact with carbon dioxide, turning it into minerals. Iceland pioneered this method using its bedrock of volcanic basalt for carbon storage. Basalt also covers most of the oceanic crust, and scientists have been exploring the potential for sub-seafloor storage reservoirs. How Iceland uses basalt to turn captured carbon dioxide into solid minerals. In the U.S., a fourth option likely has the most potential for industrial carbon dioxide storage—deep saline aquifers, which is what Google plans to use. These widely distributed aquifers are porous and permeable sediment formations consisting of sandstone, limestone, or dolostone. They’re filled with highly mineralized groundwater that cannot be used directly for drinking water but is very suitable for storing CO2. Deep saline aquifers also have large storage capacities, ranging from about 1,000 to 20,000 gigatons. In comparison, the nation’s total carbon emissions from fossil fuels in 2024 were about 4.9 gigatons. As of fall 2025, 21 industrial facilities across the U.S. used carbon capture and storage, including industries producing natural gas, fertilizer, and biofuels, according to the Global CCS Institute’s 2025 report. Five of those use deep saline aquifers, and the rest involve enhanced oil or gas recovery. Eight more industrial carbon capture facilities were under construction. Google’s plan is unique because it involves a power purchase agreement that makes building the power plant with carbon capture and storage possible. Google’s deep saline aquifer storage plan Google’s 400-megawatt natural gas power plant, to be built with Broadwing Energy, is designed to capture about 90% of the plant’s carbon dioxide emissions and pipe them underground for permanent storage in a deep saline aquifer in the nearby Mount Simon sandstone formation. The Mount Simon sandstone formation is a huge saline aquifer that lies underneath most of Illinois, southwestern Indiana, southern Ohio, and western Kentucky. It has a layer of highly porous and permeable sandstone that makes it an ideal candidate for carbon dioxide injection. To keep the carbon dioxide in a supercritical state, that layer needs to be at least half a mile (800 meters) deep. A thick layer of Eau Claire shale sits above the Mount Simon formation, serving as the caprock that helps prevent stored carbon dioxide from escaping. Except for some small regions near the Mississippi River, Eau Claire shale is considerably thick—more than 300 feet (90 meters)—throughout most of the Illinois basin. The estimated storage capacity of the Mount Simon formation ranges from 27 gigatons to 109 gigatons of carbon dioxide. The Google project plans to use an existing injection well site that was part of the first large-scale carbon storage demonstration in the Mount Simon formation. Food producer Archer Daniels Midland began injecting carbon dioxide there from nearby corn processing plants in 2012. Carbon capture and storage has had challenges as the technology developed over the years, including a pipeline rupture in 2020 that forced evacuations in Satartia, Mississippi, and caused several people to lose consciousness. After a recent leak deep underground at the Archer Daniels Midland site in Illinois, the Environmental Protection Agency in 2025 required the company to improve its monitoring. Stored carbon dioxide had migrated into an unapproved area, but no threat to water supplies was reported. Why does CCS matter? Data centers are expanding quickly, and utilities will have to build more power capacity to keep up. The artificial intelligence company OpenAI is urging the U.S. to build 100 gigawatts of new capacity every year—doubling its current rate. Many energy experts, including the International Energy Agency, believe carbon capture and storage will be necessary to slow climate change and keep global temperatures from reaching dangerous levels as energy demand rises.

Barracuda, grouper, tuna – and seaweed: Madagascar’s fishers forced to find new ways to survive

Seaweed has become a key cash crop as climate change and industrial trawling test the resilient culture of the semi-nomadic Vezo peopleAlong Madagascar’s south-west coast, the Vezo people, who have fished the Mozambique Channel for countless generations, are defined by a way of life sustained by the sea. Yet climate change and industrial exploitation are pushing this ocean-based culture to its limits.Coastal villages around Toliara, a city in southern Madagascar, host tens of thousands of the semi-nomadic Vezo people, who make a living from small-scale fishing on the ocean. For centuries, they have launched pirogues, small boats carved from single tree trunks, every day into the turquoise shallows to catch tuna, barracuda and grouper.A boat near lines of seaweed, which has become a main source of income for Ambatomilo village as warmer seas, bleached reefs and erratic weather accelerate the decline of local fish populations Continue reading...

Along Madagascar’s south-west coast, the Vezo people, who have fished the Mozambique Channel for countless generations, are defined by a way of life sustained by the sea. Yet climate change and industrial exploitation are pushing this ocean-based culture to its limits.Coastal villages around Toliara, a city in southern Madagascar, host tens of thousands of the semi-nomadic Vezo people, who make a living from small-scale fishing on the ocean. For centuries, they have launched pirogues, small boats carved from single tree trunks, every day into the turquoise shallows to catch tuna, barracuda and grouper.“We rely solely on the ocean,” says Soa Nomeny, a woman from a small island off the south-west coast called Nosy Ve. “Whatever we catch today, we eat today. If we catch nothing, we don’t eat.”That dependence is becoming precarious for the 600 or so residents of Nosy Ve. Michel “Goff” Strogoff, a former shark hunter turned conservationist from the Vezo hamlet of Andavadoaka, says fish populations began collapsing in the 1990s and have declined sharply over the past decade.Rising sea temperatures, coral bleaching and reef degradation have destroyed breeding grounds, while erratic weather linked to warming oceans has shortened fishing seasons. “There’s no abundance near shore any more,” he says. “We’re forced to paddle farther.” Soa Nomeny, wearing traditional sunblock, prepares the family’s main meal of rice and fish or octopus. The Vezo only eat that day’s catch, ensuring their meals are connected to the sea’s bounty In Nosy Ve, fish are often cooked with tomato, onion and garlic; salted sardines are laid out to dry before being sold in Andavadoaka; Soa Nomeny applies tabake, traditional sunblock made from ground taolo, a fragrant bark; and the catch is taken to market from Bevohitse village by zebu-drawn cart, the main form of transport in remote areas We still depend on fish for daily needs, but the seaweed helps us plan aheadLocal fishers echo the same concern. “There are simply too many nets out there,” says Hosoanay Natana, who now travels hours beyond traditional grounds to make a viable catch for him and his fellow fishermen.Industrial trawlers – Malagasy and foreign – often enter near-shore waters despite a national ban on the ships coming within two nautical miles (3.7km) of the coast. Weak enforcement means violations are common, leaving small-scale fishers with dwindling returns.The environmental group Blue Ventures, which has worked in the region for two decades, reports that reef fish biomass across south-west Madagascar has fallen by more than half since the 1990s. The organisation supports locally managed marine areas (LMMAs) that help communities set their own fishing rules, restore reefs and look for alternative ways to make a living.Some of the most promising of these include imposing temporary closures, which have allowed octopus stocks to rebound, and the new practice of seaweed farming, which acts as a commercial buffer against overfishing and climate shocks. Hosoanay Natana tightening the net around a school of barracuda. Divers direct boats to form a circle with the net. Once the fish are trapped, the divers retrieve them and bring them to the boat, ensuring more sustainable fishing Farther down the coast, the village of Ambatomilo, known locally as Seaweed Village, has embraced this shift. Overseen by its LMMA committee, it is among several communities cultivating seaweed as a supplementary income for fishers whose traditional grounds are overexploited. Families lay freshly harvested seaweed out to dry before selling it to local cooperatives.Fabricé and his wife, Olive, who began farming five years ago, harvest every couple of weeks. “The market pays around 1,500 ariary [25p] per kilo,” says Olive, spreading red seaweed across bamboo racks. Depending on the season, families can produce up to a tonne a month, offering significant extra income that helps cushion households’ living standards when fishing falters.“We still depend on fish for daily needs,” she says, “but the seaweed helps us plan ahead.”Seaweed farming is now one of Madagascar’s fastest-growing coastal industries. The crop is exported mainly for carrageenan – a gelling agent used in food, cosmetics and pharmaceuticals – but also serves locally as fertiliser and livestock feed. Fabricé gathers in the seaweed harvest. Depending on the season, they can harvest up to a tonne a month. With his wife, Olive, he carries the seaweed to prepare it for market. It is also eaten or used as seasoning, and serves as fertiliser or animal feed when dried. Soa Nomeny with an octopus she has speared to supplement the fish catch Environmental studies have shown that seaweed farms also help stabilise coastlines by reducing wave energy and absorbing carbon dioxide, contributing to erosion control and carbon sequestration.The Vezo people’s adaptability, once a source of pride, has become a condition of survival. Outside the cyclone season, some families still undertake long fishing migrations, camping on sandbanks and uninhabited islets as they follow fish along the coast. “Extended migrations are always an option,” says Natana. “Whether we embark or not depends on the fish stocks nearby.”Such journeys can last weeks or months, depending on catches and resources. The lure of high-value commodities – such as shark fins or sea cucumbers bound for Chinese markets – draws some to more distant waters up to 1,000 miles (1,600km) away.“Some even venture all the way to the Seychelles,” says Strogoff, a nod to the Vezo people’s enduring nomadic spirit: always chasing the next opportunity to make a living. Villagers gathered for the Tromba ritual, performed to invoke blessings, honour ancestors and seek protection, good health and plenty. People are possessed by spirits, a goat or even a zebu is sacrificed, and other offerings made, such as rice, bread or rum. The ritual is also performed at times of crisis, before a journey, or for marriages Cultural traditions remain central to community life. On Nosy Ve, families still gather for annual blessing rituals, seeking protection and prosperity. During one such ceremony, elders invoke ancestral spirits in a Tromba possession rite while villagers sacrifice a goat or make other offerings to ensure safety at sea.Life on the island reflects both endurance and fragility. Homes built from pounded seashells and palm fronds line the beach; nights are lit by torches instead of electricity.After a day at sea, the fish catches are shared equally among crews, with the surplus sold or traded for rice or solar batteries. Meals rarely change: rice, beans and grilled fish.For now, the Vezo people continue to depend on the ocean that shaped them. Yet each year, the distance they must travel grows and the risks mount.As industrial fleets expand and reefs decline, an ancient seafaring culture faces an uncertain horizon. Their struggle reflects a wider challenge across coastal Africa: how small communities can endure when the sea that sustains them is changing so fast.
