A desire to please the Court may have rendered the EPA’s new power plant rule a little too ineffectual.

If nothing else, give the Environmental Protection Agency credit for this: They seem to understand the assignment.
Last year, the Supreme Court struck down the Clean Power Plan, President Barack Obama’s ambitious attempt to restrict carbon pollution from power plants. That proposal never carried the force of law, and it had been held in suspended animation by the Court — and later the Trump administration — since 2016. But after President Joe Biden took office, Chief Justice John Roberts and the Court’s conservative majority revived it seemingly entirely for the sake of deeming it illegal.
The proposal went far beyond what was allowed by Congress, Roberts ruled. Normally, an EPA standard would require that power plants or factories install some kind of equipment on their smoke stacks to meet a pollution cap. “By contrast, and by design,” the Obama proposal could only be satisfied by burning less coal, the chief justice wrote. It required “generation shifting,” forcing states to get more of their power from renewable, nuclear, or natural-gas plants.
That overreached the EPA’s authority under the Clean Air Act, Roberts declared. If the EPA wanted to regulate greenhouse gases, then it needed to treat them like a normal air pollutant — and it needed to act like a normal technocratic agency. Above all, it had to keep its regulations to those that could be accomplished “inside the fenceline” of each power plant.
So last week, when the Biden administration finally unveiled its own draft attempt at regulating carbon pollution from power plants, it knew it was playing on the Court’s, well, court. And it behaved accordingly. The best thing you can say about the EPA’s new power-plant proposal — which will be one of the Biden era’s most important climate regulations — is that it was meticulously, painstakingly tailored to the Court’s demands. If Chief Justice Roberts asked for a normal rule, then the EPA has delivered one so awkwardly, self-consciously normal that it seems a little like a narc. The worst thing about the new rule is that this desire to please the Court may have rendered the rule a little too ineffectual.
If America wants to fight climate change, it must clean up its power plants. Generating abundant, cheap, zero-carbon electricity is the key to the country’s decarbonization strategy.
“If you clean up the power sector, it enables you to clean up other sectors of the economy too, through electrification,” Leah Stokes, an environmental-science professor at the University of California, Santa Barbara, told me. “Electric cars, heat pumps, induction stoves — all these machines can be fueled with clean power.”
Biden’s climate law, the Inflation Reduction Act, will slash emissions from the sector over the next decade, according to federal and independent modeling efforts. But it won’t get the sector all the way there. That’s where the new proposal is supposed to step in.
As per the Supreme Court’s request, the proposal details how every kind of power plant — even those that burn coal or natural gas — can meet their climate requirements for decades to come. It mandates a buildout of carbon capture and storage infrastructure, or CCS, for most coal and some natural-gas plants that plan to stay open long-term.
“The EPA rule makes sure everyone is on the same level-playing field. If the Inflation Reduction Act is enough to incentivize CCS in some places, the EPA is gonna make sure everyone is gonna do it,” Nick Bryner, a law professor at Louisiana State University, told me. “I think it’s designed very, very well to work in tandem with the IRA tax credits.”
If the IRA is the regulatory-friendly angel on its shoulder, then the Supreme Court’s decision last year — called West Virginia v. EPA — is the devil. The EPA’s desire to stay on the Court’s good side is even visible in the proposal’s name. Previous administrations have tried to give their power-plant rules a memorable name — Obama had the Clean Power Plan, of course, and the Trump administration christened its effort the “Affordable Clean Energy Rule,” or ACE. The Biden administration, by comparison, named the new proposal:
New Source Performance Standards for Greenhouse Gas Emissions from New, Modified, and Reconstructed Fossil Fuel-Fired Electric Generating Units; Emission Guidelines for Greenhouse Gas Emissions from Existing Fossil Fuel-Fired Electric Generating Units; and Repeal of the Affordable Clean Energy Rule
That’s the NSPSGHGNMRFFFEGU; EGGGEEFFFGU; RACE Rule for short.
I would say that the agency couldn’t have given it a more technocratic name if it tried, except that it obviously tried very hard. “Traditional approach, traditional name,” the EPA’s press office chirped when the Politico reporter Alex Guillén first noted the name. Just what the Supreme Court asked for!, they all but added. The agency is so desperate to look obedient and demure that even its social-media team has been briefed on current federal doctrine.
At the same time, the rule does “a tremendous amount to make the rule as flexible as possible given the constraints they’re working with in West Virginia v. EPA,” Bryner said. Under the proposal, some natural-gas plants can choose between installing carbon-capture equipment or burning low-carbon hydrogen.
But the rules may have erred on the side of too much flexibility, says Charles Harper, a policy analyst at Evergreen, a climate advocacy group and think tank. Evergreen and other environmental groups are worried that the rules might be too generous to fossil fuel companies. They’re focusing their criticism on two elements of the draft: its handling of natural-gas plants and coal retirements.
First, the EPA rule as proposed would not apply to an overwhelming majority of the country’s natural-gas plants.
A large share of carbon emissions from natural-gas plants come from so-called “baseload” plants that generate many hundreds of megawatts of electricity at all hours of the day. The rule focuses on these facilities, and it requires them either to install CCS equipment or to burn hydrogen fuel.
But the rule is not nearly so strict about small or medium-sized natural-gas plants. Natural-gas plants that generate less than 300 megawatts of electricity — or that run less than half the time — are essentially exempt from the rule. This excludes 77% of the country’s natural-gas plants from the new EPA proposal, requiring them to make no changes through 2040.
It is unclear what share of carbon emissions these natural-gas plants represent. The EPA did not provide an estimate of their carbon emissions before the deadline for this story.
As a whole, natural-gas power plants emit 43% of the U.S. electricity sector’s carbon pollution, despite producing nearly twice as much power as coal.
Environmental groups say the proposal’s coal problem is simpler to fix. In the draft, the EPA puts coal-fired power plants in different categories depending on when they’re slated to retire. Plants that have no retirement date — or that will remain open after 2040 — must install equipment to capture 90% of their emissions by the year 2030. Plants shutting down after 2035 must make a cheaper set of changes. And plants due to close by 2032 don’t have to make any changes at all, so long as they don’t increase their emissions over the next decade.
Those deadlines are too long from now, and the EPA should bring them forward in time when it issues a final version of the rule, Harper said. “2040 is pretty far out and would entail a lot of unabated emissions hitting the climate and human health,” he told me.
The EPA still has time to edit this proposal; it will hear public comment over the next few months and probably issue a final version of the rule next year. With the procedural issues resolved, the Supreme Court’s ability to object to that rule is limited to whether carbon capture is feasible and affordable enough to be used under the Clean Air Act.
If there is a bright spot for climate advocates in the new rule, it’s that the Biden administration — and last year’s Democratic majority in Congress — seem to have anticipated that move.
As the House was voting on the IRA last year, Representative Frank Pallone, the chair of the House Energy and Commerce Committee, put a statement in the congressional record saying that the EPA should take the IRA’s generous tax credits into account when proposing power-plant rules. The subsidies should be considered when the agency is deciding whether CCS is feasible and affordable, he said. The EPA cites Pallone’s statement in its new draft.
But ultimately it is Chief Justice John Roberts who will get to decide. Almost a decade ago, a set of conservative states sued the EPA to block it from requiring CCS. That issue has since been held in its own state of suspended animation. It may soon breathe again.

Most Americans still say they would oppose a data center being built near where they live, but the facilities’ standing has improved among Republicans, a new Heatmap Pro poll finds.
The American public’s backlash against data centers may finally be starting to slow down, although the facilities remain staggeringly unpopular, a new poll finds.
Seventy-one percent of Americans said they would oppose a data center being built near where they live, according to a new Heatmap Pro poll conducted by Embold Research earlier this month.
That is an abysmal finding for technology companies and would-be developers of the computing facilities. But it actually represents an improvement from previous polling, and it suggests one of the fastest shifts in public opinion in recent memory may be tapering off.
That shift has been swift. As recently as September of last year, about 43% of Americans said they would support a data center being built near where they live, and Americans broadly appeared to be evenly split on the infrastructure, according to Heatmap Pro polling. Eleven months later, 75% of Americans told the same poll that they would oppose a nearby data center — a 32 point shift. That monumental turnaround helped make data centers a defining issue in this election cycle.
That backlash has transformed the economics of the data center boom, the largest infrastructure buildout in recent U.S. history. The overwhelming majority of data center projects now face some degree of community opposition, Heatmap Pro reporting suggests. More than $260 billion in proposed data centers have been canceled this year after meeting local opposition. The artificial intelligence company Anthropic even flagged the infrastructure slowdown on Monday when it filed for its initial public offering, which is widely expected to be among the largest ever.
Now our new survey shows that Americans’ rejection of the enormous computing facilities may itself be slowing. The small observed drop, which only slightly exceeds the survey’s margin of error, was driven by a four-point decline in the share of Americans who said they would “strongly oppose” the technology.

While Americans of all parties improved their view of data centers, the change was most pronounced among Republicans. In August, 23% of GOP voters said that they would support a data center being built near where they live. In the new poll, conducted after weeks of favorable campaigning by President Trump, 34% of Republicans said they would support a data center slated for their area, while the share of Republicans who said they would oppose it fell from 66% to 58%. Data centers’ standing among independents improved by nine points during the same period.
Democrats remain largely unified against the infrastructure, and data centers’ improvement among that group was just outside the margin of error.
While Americans of every age, race, gender, and partisan ID remain more opposed to local data center development than in favor of it, their standing has also improved among men since the summer. In August, 21% of men said they would support a data center being built near where they live. Now, 28% of men would support one.
Will America be the land of opportunity for AtkinsRéalis’ tried-and-true CANDU?
Unruffled by President Trump’s taunts of turning Canada into the 51st state, Canadian Prime Minister Mark Carney has vowed to regain leverage over Washington by remaking his nation as an “energy superpower.” Instead of building pipelines from the oil fields of Alberta to American refineries, Ottawa will run them to its West Coast ports to sell crude directly to Asia. Rather than importing electricity from offshore wind farms in the American Northeast, Nova Scotia will build its own turbines and sell the power back to energy-starved New England as the Trump administration thwarts the region’s own buildout.
But Canada’s path to reviving its nuclear industry may run — counterintuitively — through the United States.
Last week, Montreal-based AtkinsRéalis inked a deal with utility Hoosier Energy and the Indiana government to explore building up to 6 gigawatts of reactors in the state. The agreement is only a memorandum of understanding to kick off a study examining potential sites across the state. But it marks the first real effort to export Canada’s unique pressurized heavy-water reactors, called CANDUs, to the U.S., and highlights how America’s domestic nuclear industry has atrophied to the point that foreign developers of large-scale units are racing to establish a beachhead in the world’s largest atomic power market.
“If the Americans had created the CANDU, everyone in the world would know about it,” Joe St. Julian, the American-born president of AtkinsRéalis, told me. “There’s just a cultural difference in the way that the Canadians go about things and the way the Americans do.”
Pronounced “CAN-do,” the upbeat acronym stands for Canada Deuterium Uranium and evokes the government’s post-war, can-do spirit, mustered to help protect its sovereignty during the bipolarity of the Cold War. Developed in the 1950s by Canadian government scientists and now used across the country’s entire nuclear fleet, CANDUs rely on deuterium, a version of hydrogen with an extra neutron, as their “heavy water” coolant to sustain their chains of split atoms. Uranium powers virtually all commercial nuclear reactors, but CANDUs are distinct in that they can run on the raw stuff, rather than enriched uranium. That’s their real advantage: By forgoing the costly and heavily scrutinized enrichment process, Canada can tap its vast resources of mined uranium without facing the bottleneck of the expensive enrichment facilities or attracting the intensive oversight of global regulators monitoring for the production of atomic weapons.
The 17 reactors that provide 15% of Canada’s electricity today are all CANDUs. India’s fleet largely borrowed the technology, and Argentina, China, Romania, and South Korea have all imported their own CANDUs. But the buildout largely stopped in the last century. Canada built its last CANDU in Romania in 2007. The last Canadian CANDU — Unit 4 of the Darlington nuclear plant in Ontario — came online in 1993.
Two years ago, Canada sought to restart its reactor buildout by commissioning its first American-designed unit. Construction began last year on the world’s first BWRX-300, a small modular reactor that uses enriched uranium as fuel. The U.S. plans to build the second version of the same reactor at the Tennessee Valley Authority’s Clinch River site. Whether it can deliver the cost savings SMRs promise remains an open question, given that nuclear developers have historically improved economics by making reactors bigger, not smaller.
But Chris Keefer, a Toronto physician-cum-nuclear advocate who hosts the in-depth energy podcast Decouple, told me he believes Canada’s real error is in benching the CANDU. While Ontario’s government-owned utility “got their backs slapped endlessly for having the courage to go first” in building the inaugural SMR on the continent, “they’re idiots to be investing $21 billion of Canadian ratepayers’ money to prop up an American company with American technology,” he said, colorfully characterizing the move as a massive error and “the result of dis-coordinated decision-making.” (Converted from loonies to U.S. dollars, that figure is about $14.9 billion.)
While Keefer added that he opposes the trade war between Washington and Ottawa, he also recognizes it as a potential opening. “Part of me loves it and this deglobalization moment we’re in, where strategic autonomy and national interest matter,” he said.
The Carney administration has yet to set clear rules on what kind of reactor technology it will support domestically, but it could, in theory, limit access to federal subsidies for provinces and utilities that opt for non-CANDU technologies. For now, however, there appears to be quiet agreement between the U.S. and Canada on bringing the technology south. St. Julian said the Canadian Ministry of Energy has been “very supportive” in talks about providing financing for CANDU exports to the U.S. AtkinsRéalis is also in talks with the U.S. Department of Energy, though a source familiar with that agency’s thinking cast doubt over the possibility that the Trump administration would ultimately fund a Canadian project in the U.S.
None of this was a part of AtkinsRéalis’ long game, St. Julian told me. “The U.S. had four or five of its own reactor technologies,” he said. “Why would it build a foreign technology?” But shortly after Trump returned to office, “We looked at it and realized the U.S. is down to a single large reactor technology: Westinghouse. The other three or four are no longer in business.”
That was the opening AtkinsRéalis needed. “The U.S. made clear it had the aspiration to build 300 new nuclear power stations,” St. Julian went on. “Between Westinghouse and new technologies coming online with SMRs, we said they couldn’t possibly reach their aspiration no matter how optimistic they are about the capacity and supply chain of first-of-a-kind technologies.”
So the company applied to the U.S. Nuclear Regulatory Commission for approval of the CANDU. In June, AtkinsRéalis sent the regulator a formal heads-up about its plans to file an application this past summer, and it expects to complete its second topical report for the NRC by the end of this month.
The CANDUs aren’t the only foreign reactors making a play in the U.S., though. Last month, South Korea unveiled a deal with the Trump administration to fund construction of up to six AP1000s and two APR1400s.
The CANDU does have some drawbacks that the APR1400 doesn’t. The same characteristics that let its reactors sustain fission using raw uranium also cause wear and tear that requires a significant refurbishment every 35 years. (Canada is already funding a campaign of repairs domestically.) And while a typical refueling outage for a light water reactor lasts up to two months and renovations ahead of a relicensing can take up to a year, the refurbishment process for a CANDU can take the unit offline for two years or more.
AtkinsRéalis declined to comment on its internal estimates of the cost of such a refurbishment, which is — among industry experts — widely criticized as costly. But St. Julian said the company guarantees at least two refurbishments in a CANDU’s lifetime, giving each unit a 105-year lifespan. Amortizing the costs over more than a century of electricity production, not to mention the company’s experience building units all over the world, means a CANDU is “a lot less expensive” than rival technologies, he said.
“The APR1400’s biggest advantage is the Korean industrial ecosystem,” Nana Menya Ayensu, a non-resident senior fellow at the Atlantic Council who worked on energy policy in the Biden White House, told me. “But the CANDU has lots of advantages that are specific to the technology in terms of not needing enriched fuel.”
Keefer highlighted another upside he’s acutely aware of due to his day job as an emergency-room doctor: CANDUs are particularly well-suited to batch-producing “enormous amounts” of medical isotopes, such as cobalt-60, used in cancer chemotherapy and the sterilization of surgical instruments, among other uses.
The technology is certainly attracting attention. Last month, Argentina and Romania agreed to work together on more CANDU projects. Weeks later, as I reported, Poland’s state-backed nuclear developer approved a tender for a second nuclear power station, for which it’s considering the CANDU. Last week, Turkey signed an agreement with Carney to cooperate on civilian nuclear energy, putting the CANDU in contention for the country’s second atomic power station.
And earlier this month, Atlas Atomics, a startup backed by Ohio’s Republican gubernatorial candidate Vivek Ramaswamy, raised $400 million in a Series A to commercialize its own pressurized heavy water reactor, in what Keefer dubbed in his newsletter the “AmeriCANDU.”
St. Julian said the new competition shows the unique value of the CANDU. “The difference is, we’ve been doing it for 70 years, and we spent tens of millions of dollars to perfect this technology; they’re just starting,” he said. Then he cracked a half smile. “They have the benefit of being a second movement,” he added. “But, man, we have a big head start.”
Plus, one big opportunity for climate change.
Anthropic is worried about its ability to power data centers.
While much of the company’s more-than-330-page filing for its planned initial public offering focuses on the mundane (executive compensation) and the extraordinary (“existential risks” are mentioned three times), considerable space is devoted to the problems of power.
The word “energy” appears 14 times in the section of the document laying out risks to Anthropic’s business, while “climate” or “climate change” is mentioned four times.
The overarching concern the company has is that it might not get enough power for data centers running its large language models. “Delays in securing energy, water, and other critical services for these facilities could further slow the pace at which newly commissioned compute becomes available for use,” is one representative sample from its risk factors section. The document later notes that “our business may face increased scrutiny related to these activities … including from the investment community and the local communities in which we operate,” in a later section on environmental, social, and governance standards.
Anthropic is also concerned with the pace of the energy infrastructure build-out more generally, noting “the construction of the generation and transmission infrastructure on which we depend is itself capital-intensive and exposed to labor shortages, supply chain disruptions, permitting delays, changes in interest rates, tariffs, other cost overruns, and financing constraints.” These concerns will be familiar to anyone following the debate in Washington, D.C., over permitting reform, which is also centered on making transmission easier and cheaper to build.
Later in the document, Anthropic writes that electricity policy is both highly varied across the country — “Grid-tied electrical supply, for instance, is subject to the jurisdiction of federal and state energy regulators, regional grid operators, and public utility commissions” — and also evolving, noting specifically that “environmental standards applicable to power generation continue to evolve, including as a result of changing governmental priorities and shifting public and political views regarding climate change and the appropriate treatment of various power generation sources.”
The risk of these policies is that they could result in “failure to secure access to adequate electrical power,” which could then “adversely affect our cost structure and limit our ability to scale our compute infrastructure, develop and deploy our models, and service our customers.”
Anthropic also acknowledges energy can be quite expensive, writing that costs are “largely outside of our control” and can “rise sharply during periods of peak demand or constrained supply, and such increases in energy costs could adversely affect our results of operations.”
Anthropic is the charter member of an industry group, along with Nvidia and Google, to promote and enable demand flexibility, which would reduce peak demand — and thus bring down electricity prices and alleviate the need for additional new infrastructure — by having data centers draw down their power usage when demand was at its highest. The company notes that it has also signed on to “voluntary commitments to offset the impact of our data center energy consumption on local communities and electricity ratepayers.” Already, the document says, “these commitments have increased, and we expect will continue to increase, our operating costs.”
And while the document has little to say about climate change per se and even less about sustainability and renewables, it does note that “the physical effects of climate change may increase our operating costs over time, as higher average temperatures can increase the power consumption and water usage required to cool equipment at the facilities on which we depend.”
Climate change also acts as an amplifier for potential disasters that could affect the company. “The impact of climate change may increase these risks,” the company says of “war, terrorist attacks, and other acts of political violence, or any significant natural disaster, such as an earthquake, fire, hurricane, tornado, flood, or significant power outage.”
Specifically, Anthropic calls out climate-related risk specific to the Bay Area, where it is headquartered. Or, as it bloodlessly describes it, “a region known for seismic activity and increasingly for the threat of fires.”
Otherwise, climate change and sustainability policy is largely seen as a regulatory and cost burden. For example, “regulations relating to [environmental, social, and governance] matters, including environmental sustainability and climate change, are under consideration, being adopted, or being rolled back or revised, which may impact our necessary disclosures and increase compliance costs,” and “sustainability initiatives, goals, or commitments could be difficult to achieve or costly to implement.”
It notes a variety of California, European Union, and United Kingdom climate disclosure laws “will require the dedication of significant time and resources” while also observing that “across the United States ... enacted or proposed ‘anti-ESG’ policies or legislation or have issued related legal opinions,” which could “expose any sustainability, employment, governance, or other corporate practices we adopt to the risk of litigation, antitrust investigations or challenges by federal or state authorities, and result in injunctions, penalties, and reputational harm.”
The document is far less detailed about what Anthropic and its products could do to alleviate or prevent climate change and its effects. This is not surprising for a regulatory filing concerned with disclosing corporate information and outlining risks to investors — but the filing is also supposed to explain the business opportunities it sees as well. In that regard, climate is relegated to a laundry list of potential scientific projects Anthropic’s products could be helpful with. “Claude is also being applied to pressing global problems in scientific research, drug discovery, education, and climate analysis,” it writes.
If its S-1 is any indication, there will be a lot of work to do.
