What the Council on Foreign Relations’ new climate program gets drastically wrong.

Let’s start with two basic facts.
First, the climate crisis is here now, killing people, devastating communities, and destroying infrastructure in Los Angeles and Asheville and Spain and Pakistan and China. And it will get worse.
Second, Donald Trump is the President of the United States. He began the process to withdraw the United States from the Paris Agreement on January 20, 2025, his first day in office in his second term. (He, of course, did this in his first term as well.) He illegally froze funding for climate programs that had passed and became law during the Biden administration, and his administration continues to ignore court orders to unfreeze these monies. He has signed numerous executive orders, including on reinvigorating clean [sic] coal, reversing state-level climate policies, “Zero-based regulatory budgeting to unleash American energy,” and “unleashing” American energy, the last of which revoked more than a dozen Biden era executive orders.
How do we address a world that is increasingly shaped by these two facts?
One attempt can be seen in the Council on Foreign Relations’s new “Climate Realism Initiative.” Its statement of purpose attempts to make climate action palatable to MAGA world by securitizing it, framing climate change as a foreign threat to Fortress America. It calls for investing in next-generation technologies and geoengineering in the hopes of leapfrogging the Chinese-led clean energy revolution that is beginning to decarbonize the world today is the best realistic way forward.
This attempt is doomed to failure. Real climate realism for the United States is to stop the destruction of American state capacity, and then to reflect and build on areas of core strength including finance and software.
CRI’s launch document does not call for the U.S. to reduce its own emissions. I’ll say that again: There is no call for the U.S. to reduce its own emissions in the essay establishing the mission and objectives of the Climate Realism Initiative. Written by Varun Sivaram, formerly chief strategy and innovation officer at wind energy developer Orsted and now the leader of the initiative, the essay proposes that four dug-in “fallacies” are getting in the way of effective policy-making: that climate change “poses a manageable risk” to the U.S.; that “the world’s climate targets are achievable;” that the clean energy transition is a “win-in for U.S. interests and climate action;” and that “reducing U.S. domestic greenhouse gas emissions can make a meaningful difference.” For Sivaram, the problem is always other places and their emissions.
He then goes on to propose three “pillars” of climate realism: the need for America to prepare for a world “blowing through climate targets;” to “invest in globally competitive clean technology industries;” and to “lead international efforts to avert truly catastrophic climate change.” How an America that does not commit to reduce its own emissions will have any credibility or standing to lead international efforts is left unstated.
Sivaram attempts to trick the reader into overlooking America’s emissions by ignoring the facts of the past and focusing instead on guesses about the future. It’s true that in 2023, China produced more than a quarter of new global carbon pollution — more than the United States, Europe, and India combined. But no country has contributed more to the blanket of pollution that traps additional heat in our atmosphere than the United States, which has emitted over 430 billion tons of CO2, or 23% of the world’s total historical emissions. Even in 2023, the U.S. remained the world’s number two carbon polluter.
Sivaram goes further than merely minimizing the U.S. role in creating our current climate problems. Indeed, he sets up climate change as a problem that foreign countries are imposing on Americans. “Foreign emissions,” he writes, “are endangering the American homeland,” and the effects of climate disasters “resemble those if China or Indonesia were to launch missiles at the United States.” There is something to this rhetoric that is powerful — we should think about climate-induced disasters as serious threats and respond to them with the kind of resources that we lavish on the military industrial complex. But the idea that it is foreign emissions that are the primary source of this danger is almost Trumpian.
The initiatives proposed in the Climate Realism launch are the initiatives of giving up. Investing in resilience and adaptation is needed in any scenario, but tying this spending on adaptation to Trumpian notions of protecting our borders reeks of discredited lifeboat ethics, which only cares to save ourselves and leaves others to suffer for our sins. And while supporting next-generation technologies is an appropriate piece of the policy puzzle, they should be like the broccoli at a steakhouse: off to the side and mostly superfluous compared with the meat and potatoes of deployment and mitigation to decarbonize today.
Sivaram may argue that there’s no point in trying to compete against China in the technologies of today when Chinese firms are so dominant and apparently willing to make these products while earning minimal profits. And from a parochial profit-maximizing perspective, there is a business case that firms should not be building lots of new solar cell manufacturing facilities given global manufacturing capacity.
But if American automotive firms simply ignore the coming EV wave and hope against hope that some breakthrough in solid state batteries will allow them to leapfrog over the firms vying today, they are fooling themselves. Electric vehicle giant BYD and world-leading battery manufacturer CATL have both announced batteries that can charge a car in five minutes. Both are also moving in the solid state space, and CATL is pushing into sodium ion batteries.
The notion that U.S. firms ought to sit out this fight for strategic reasons also ignores how China has come to dominate these sectors — by investing in today’s state of the art and pushing it forward through incremental process improvements at scale. The Thielian notion that “competition is for losers” leads to an immense amount of waste as wannabe founders search for unbreakable technological advantages. If venture capitalists want to fund such bets, I’m not going to stop them. But as a policy prescription for climate realism, it fails.
The final gambit of the essay is to advocate for America-controlled geoengineering. This, too, is an area where research may be needed. But regardless, it is the kind of emergency backup plan that you hope that you never need to use, rather than something that should be central to anyone’s policy strategy. Trump is currently decimating American capacity to research hard problems, whether they be cancer or vaccines or social science or anything else, so it is difficult to imagine that this administration is likely to spend real resources to investigate geoengineering.
The Climate Realism Initiative pitches itself as “bipartisan.” But where is the MAGA coalition that supports this? Even simple spending on adaptation and resilience seems unlikely to find much of a political home given the Trump administration’s drastic cuts in weather and disaster forecasting. Sivaram even mentions the need to balance the budget as part of climate realism, which must be a sick joke. For all of the fanfare over cuts to the federal government under Trump, the budget deficit is the last thing that they care about. Tax cuts remain the coin of the realm, with the House budgetary guidelines expanding the deficit by $2.8 trillion. Elon Musk’s Department of Government Efficiency, similarly, has a distorted notion of government efficiency, ignoring the returns to government investments and gutting the tax collection capacity of the IRS.
The Biden administration had plans — “all of the above” energy among them — that were coherent, if not necessarily the most appealing to the world. They were based on the idea that a resilient climate coalition in the U.S. required more than just deploying Chinese-made products.
CRI seems to want to engage instead in a fantasy conversation where anti-Chinese nationalism can unite Americans to fight climate change — an all-form, no-content negative sum realpolitik that does little to address the real, compelling, and deeply political questions that the climate crisis poses.
Alternative visions are possible. The American economy is services based. Americans and American firms will inevitably make some of the hardware components of the energy transition, but the opportunities that play to our strengths are mostly on the software side.
It is critical to remember that the clean technologies that power the energy transition are categorically different from the fossil fuels that the world burned (and still burns) for energy. We do not require a constant stream of these technologies to operate our economy. The solar panels on your roof or in the field outside of town still generate electricity even if you can’t buy new ones because of a trade war. Same with wind turbines. In fact, renewables are a source of energy security because the generation happens from domestic natural resources — the sun and wind. Yet smart thinkers like Jake Sullivan fall into the trap of treating “dependence” on Chinese renewable technologies as analogous to European dependence on Russian natural gas.
Even China’s ban on U.S.-bound rare earth exports won’t make much of a dent. Despite the name, rare earths aren’t that rare, and while China does dominate their processing, it’s a tiny industry; in making fun of the “critical” nature of rare earths, Bloomberg opinion writer Javier Blas noted that the total imports of rare earths from China to the U.S. in 2024 was $170 million, or about 0.03% of U.S.-China trade. That being said, the major concern is if supplies fall to zero then major processes that require tiny amounts of rare earths (like Yttria and turbine construction) could be completely halted with serious fallout.
The American government should carefully choose what industries it would like to support. Commodity factories that have little-to-no profits, like solar cells, seem unattractive. There are many more jobs in installing solar than there are in manufacturing it, after all.
On the other hand, sectors with a much larger existing domestic industry, such as wind turbines and especially automobiles, should not be left to wither. But rather than a tariff wall to protect them, the U.S. auto firms should be encouraged to partner with the leading firms — even if those firms are Chinese — to build joint ventures in the American heartland, so that they and the American people can participate in the EV shift.
But the core of real climate realism for the United States is not about new factories. It’s about playing to our strengths. The United States has the best finance and technology sectors in the world, and these should be used to help decarbonize at home and around the world. This climate realism agenda can come in left- and right-wing flavors. A leftist vision is likely state-led with designs, guides, and plans, while the right-wing vision relies on markets.
Take Texas. On May 7, 2020, the Texas grid set a record with 21.4 gigawatts of renewable electricity generation. Just five years later, that figure hit 41.9 gigawatts. Solar and batteries have exploded on the grid, with capacity hitting 30 gigawatts and 10 gigawatts respectively. They have grown so rapidly because of the state’s market-based system, with its low barriers to interconnection and competitive dynamics.
Of course, not every location is blessed with as much wind, sun, and open space as Texas. But there’s no reason why its market systems can’t be a template for other states and countries. This, too, is industrial policy — not just the factory workers building the technologies or even the installers deploying them. There is lots of work for the lawyers and power systems engineers and advertisers and policy analysts and bankers and consultants, as well.
Yet instead of seizing these real chances to push climate action forward at home and abroad, the Trump administration is eviscerating American state capacity, the rule of law, and global trust in the government. The whipsawing of Trump’s tariffs generates uncertainty that undercuts investment. The destruction of government support for scientific exploration hits at the next-generation moonshots that Sivaram is so enamored of, as well as the institutions that educate our citizens and train our workforce. Trump’s blatant disregard for court orders and his regime’s cronyism undercut belief in the rule of law, and that investments will rise and fall based on their economics rather than how close they are to the President.
But it’s not just Trump. Texas legislators are on the verge of destroying the golden goose of cheap electricity through rapid renewables deployment out of a desire to own the libs. Despite the huge economic returns to rural communities that have seen so much utility-scale expansion in the state, some Republican legislators are pushing bills that would stick their fingers into the electricity market pie, undercutting the renewable expansion and mandating expensive gas expansion.
The Trump business coalition, which was mostly vibes in the first place, is fracturing. There are conflicting interests between those who want to fight inflation and those who see low oil prices as a problem. Pushing down oil prices by pressuring OPEC+ to pump more crude and depressing global economic outlooks with the trade war (Degrowth Donald!) has hurt the frackers in Texas. Ironically, one way to lower their costs is to electrify operations, so they don’t have to rely on expensive diesel.
Climate change is here, but so is Donald Trump. Ignoring either one is a recipe for disaster as they both create destructive whirlwinds and traffic in uncertainty. The real solution to both is mitigation — doing everything possible today to stop as much of the damage as possible before it happens.

Rob takes Jesse through our battery of questions.
Every year, Heatmap asks dozens of climate scientists, officials, and business leaders the same set of questions. It’s an act of temperature-taking we call our Insiders Survey — and our 2026 edition is live now.
In this week’s Shift Key episode, Rob puts Jesse through the survey wringer. What is the most exciting climate tech company? Are data centers slowing down decarbonization? And will a country attempt the global deployment of solar radiation management within the next decade? It’s a fun one! Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

Here is an excerpt from our conversation:
Robinson Meyer: Next question — you have to pick one, and then you’ll get a free response section. Do you think AI and data centers energy needs are significantly slowing down decarbonization, yes or no?
Jesse Jenkins: Significantly. Yeah, I guess significantly would … yes, I think so. I think in general, the challenge we have with decarbonization is we have to add new, clean supplies of energy faster than demand growth. And so, in order to make progress on existing emissions, you have to exceed the demand growth, meet all of that growth with clean resources, and then start to drive down emissions.
If you look at what we’ve talked about — are China’s emissions peaking, or global emissions peaking? I mean, that really is a game. It’s a race between how fast we can add clean supply and how fast demand for energy’s growing. And so in the power sector in particular, an area where we’ve made the most progress in recent years in cutting emissions, now having a large, and rapid growth in electricity demand for a whole new sector of the economy — and one that doesn’t directly contribute to decarbonization, like, say, in contrast to electric vehicles or electrifying heating —certainly makes things harder. It just makes that you have to run that race even faster.
I would say in the U.S. context in particular, in a combination of the Trump policy environment, we are not keeping pace, right? We are not going to be able to both meet the large demand growth and eat into the substantial remaining emissions that we have from coal and gas in our power sector. And in particular, I think we’re going to see a lot more coal generation over the next decade than we would’ve otherwise without both AI and without the repeal of the Biden-era EPA regulations, which were going to really drive the entire coal fleet into a moment of truth, right? Are they gonna retrofit for carbon capture? Are they going to retire? Was basically their option, by 2035.
And so without that, we still have on the order of 150 gigawatts of coal-fired power plants in the United States, and many of those were on the way out, and I think they’re getting a second lease on life because of the fact that demand for energy and particularly capacity are growing so rapidly that a lot of them are now saying, Hey, you know what, we can actually make quite a bit of money if we stick around for another 5, 10, 15 years. So yeah, I’d say that’s significantly harder.
That isn’t an indictment to say we shouldn’t do AI. It’s happening. It’s valuable, and we need to meet as much, if not all of that growth with clean energy. But then we still have to try to go faster, and that’s the key.

They still want to decarbonize, but they’re over the jargon.
Where does the fight to decarbonize the global economy go from here? The past 12 months, after all, have been bleak. Donald Trump has pulled the United States out of the Paris Agreement (again) and is trying to leave a precursor United Nations climate treaty, as well. He ripped out half the Inflation Reduction Act, sidetracked the Environmental Protection Administration, and rechristened the Energy Department’s in-house bank in the name of “energy dominance.” Even nonpartisan weather research — like that conducted by the National Center for Atmospheric Research — is getting shut down by Trump’s ideologues. And in the days before we went to press, Trump invaded Venezuela with the explicit goal (he claims) of taking its oil.
Abroad, the picture hardly seems rosier. China’s new climate pledge struck many observers as underwhelming. Mark Carney, who once led the effort to decarbonize global finance, won Canada’s premiership after promising to lift parts of that country’s carbon tax — then struck a “grand bargain” with fossiliferous Alberta. Even Europe seems to dither between its climate goals, its economic security, and the need for faster growth.
Now would be a good time, we thought, for an industry-wide check-in. So we called up 55 of the most discerning and often disputatious voices in climate and clean energy — the scientists, researchers, innovators, and reformers who are already shaping our climate future. Some of them led the Biden administration’s climate policy from within the White House; others are harsh or heterodox critics of mainstream environmentalism. And a few more are on the front lines right now, tasked with responding to Trump’s policies from the halls of Congress — or the ivory minarets of academia.
We asked them all the same questions, including: Which key decarbonization technology is not ready for primetime? Who in the Trump administration has been the worst for decarbonization? And how hot is the planet set to get in 2100, really? (Among other queries.) Their answers — as summarized and tabulated by my colleagues — are available in these pages.
You can see whether insiders think data centers are slowing down decarbonization and what folks have learned (or, at least, say they’ve learned) from the repeal of clean energy tax credits in the Inflation Reduction Act.
But from many different respondents, a mood emerged: a kind of exhaustion with “climate” as the right frame through which to understand the fractious mixture of electrification, pollution reduction, clean energy development, and other goals that people who care about climate change actually pursue. When we asked what piece of climate jargon people would most like to ban, we expected most answers to dwell on the various colors of hydrogen (green, blue, orange, chartreuse), perhaps, or the alphabet soup of acronyms around carbon removal (CDR, DAC, CCS, CCUS, MRV). Instead, we got:
“‘Climate.’ Literally the word climate, I would just get rid of it completely,” one venture capitalist told us. “I would love to see people not use 'climate change' as a predominant way to talk to people about a global challenge like this,” seconded a former Washington official. “And who knows what a ‘greenhouse gas emission’ is in the real world?” A lobbyist agreed: “Climate change, unfortunately, has become too politicized … I’d rather talk about decarbonization than climate change.”
Not everyone was as willing to shift to decarbonization, but most welcomed some form of specificity. “I’ve always tried to reframe climate change to be more personal and to recognize it is literally the biggest health challenge of our lives,” the former official said. The VC said we should “get back to the basics of, are you in the energy business? Are you in the agriculture business? Are you in transportation, logistics, manufacturing?”
“You're in a business,” they added, “there is no climate business.”
Not everyone hated “climate” quite as much — but others mentioned a phrase including the word. One think tanker wanted to nix “climate emergency.” Another scholar said: “I think the ‘climate justice’ term — not the idea — but I think the term got spread so widely that it became kind of difficult to understand what it was even referring to.” And one climate scientist didn’t have a problem with climate change, per se, but did say that people should pare back how they discuss it and back off “the notion that climate change will result in human extinction, or the sudden and imminent end to human civilization.”
There were other points of agreement. Four people wanted to ban “net zero” or “carbon neutrality.” One scientist said activists should back off fossil gas — “I know we’re always trying to try convince people of something, but, like, the entire world calls it ’natural gas’” — and another scientist said that they wished people would stop “micromanaging” language: “People continually changing jargon to try and find the magic words that make something different than it is — that annoys me.”
Two more academics added they wish to banish discussion of “overshoot”: “It’s not clear if it's referring to temperatures or emissions — I just don't think it's a helpful frame for thinking about the problem.”
“Unit economics,” “greenwashing,” and — yes — the whole spectrum of hydrogen colors came in for a lashing. But perhaps the most distinctive ban suggestion came from Todd Stern, the former chief U.S. climate diplomat, who negotiated the Kyoto Protocol and the Paris Agreement.
“I hate it when people say ’are you going to COP?’” he told me, referring to the United Nations’ annual climate summit, officially known as the Conference of the Parties. His issue wasn’t calling it “COP,” he clarified. It was dropping the definite article.
“The way I see it, no one has the right to suddenly become such intimate pals with ‘COP.’ You go to the ball game or the conference or what have you. And you go to ‘the COP,’” he said. “I am clearly losing this battle, but no one will ever hear me drop the ‘the.’”
Now, since I talked to Stern, the United States has moved to drop the COP entirely — with or without the “the” — because Trump took us out of the climate treaty under whose aegis the COP is held. But precision still counts, even in unfriendly times. And throughout the rest of this package, you’ll find insiders trying to find a path forward in thoughtful, insightful, and precise ways.
You’ll also find them remaining surprisingly upbeat — and even more optimistic, in some ways, than they were last year. Twelve months ago, 30% of our insider panel thought China would peak its emissions in the 2020s; this year, a plurality said the peak would come this decade. Roughly the same share of respondents this year as last year thought the U.S. would hit net zero in the 2060s. Trump might be setting back American climate action in the near term. But some of the most important long-term trends remain unchanged.

All participants were given the opportunity to record responses anonymously. Not all respondents answered all questions.
Plus, which is the best hyperscaler on climate — and which is the worst?
The biggest story in energy right now is data centers.
After decades of slow load growth, forecasters are almost competing with each other to predict the most eye-popping figure for how much new electricity demand data centers will add to the grid. And with the existing electricity system with its backbone of natural gas, more data centers could mean higher emissions.
Hyperscalers with sustainability goals are already reporting higher emissions, and technology companies are telling investors that they plan to invest hundreds of billions, if not trillions of dollars, into new data centers, increasingly at gigawatt scale.
And yet when we asked our Heatmap survey participants “Do you think AI and data centers’ energy needs are significantly slowing down decarbonization?” only about 34% said they would, compared to 66% who said they wouldn’t.
There were some intriguing differences between different types of respondents. Among our “innovator” respondents — venture capitalists, founders, and executives working at climate tech startups — the overwhelming majority said that AI and data centers are not slowing down decarbonization. “I think it’s the inverse — I think we want to launch the next generation of technologies when there’s demand growth and opportunity to sell into a slightly higher priced, non-commoditized market,” Joe Goodman co-founder and managing partner at VoLo Earth Ventures, told us.
Not everyone in Silicon Valley is so optimistic, however. “I think in a different political environment, it may have been a true accelerant,” one VC told us. “But in this political environment, it’s a true albatross because it’s creating so many more emissions. It’s creating so much stress on the grid. We’re not deploying the kinds of solutions that would be effective."
Scientists were least in agreement on the question. While only 47% of scientists thought the growth of data centers would significantly slow down decarbonization, most of the pessimistic camp was in the social sciences. In total, over 62% of the physical scientists we surveyed thought data centers weren’t slowing down decarbonization, compared to a third of social scientists.
Michael Greenstone, a University of Chicago economist, told us he didn’t see data centers and artificial intelligence as any different from any other use of energy. “I also think air conditioning and lighting, computing, and 57,000 other uses of electricity are slowing down decarbonization,” he said. The real answer is the world is not trying to minimize climate change.”
Mijin Cha, an assistant professor of environment studies at the University of California Santa Cruz, was even more gloomy, telling us, “Not only do I think it’s slowing down decarbonization, I think it is permanently extending the life of fossil fuels, especially as it is now unmitigated growth.”
Some took issue with the premise of the question, expressing skepticism of the entire AI industry. “I’m actually of the opinion that most of the AI and data center plans are a massive bubble,” a scientist told us. “And so, are there plans that would be disruptive to emissions? Yes. Are they actually doing anything to emissions yet? Not obvious.”
We also asked respondents to name the “best” and “worst” hyperscalers, large technology companies pursuing the data center buildout. Many of these companies have some kind of renewables or sustainability goal, but there are meaningful differences among them. Google and Microsoft look to match their emissions with non-carbon-power generation in the same geographic area and at the same time. The approach used by Meta and Amazon, on the other hand, is to develop renewable projects that have the biggest “bang for the buck” on global emissions by siting them in areas with high emissions that the renewable generation can be said to displace.
Among our respondents, the 24/7 “time and place” approach is the clear winner.
Google was the “best” pick for 19 respondents, including six who said “Google and Microsoft.” By contrast, Amazon and Meta had just three votes combined.
As for the “worst,” there was no clear consensus, although two respondents from the social sciences picked “everyone besides Microsoft and Google” and “everyone but Google and Microsoft.” Another one told us, “The best is a tie between Microsoft and Google. Everyone else is in the bottom category.”
A third social scientist summed it up even more pungently. “Google is the best, Meta is the worst. Evil corporation” — though with more expletives than that.
