In a word: chaos.

A moment of profound uncertainty for many of America’s environmental laws has just become even more uncertain-er. This week, as President-elect Donald Trump considers how to revise or repeal the country’s bedrock climate laws, one of the country’s oldest environmental laws has been thrown into jeopardy.
A three-judge panel on the D.C. Circuit Court of Appeals ruled earlier this week that key rules governing the National Environmental Policy Act, which requires the federal government to study the environmental impact of its actions, do not carry the force of law. The ruling might — might — lay the groundwork for a massive revolution in the country’s environmental permitting regime. But for the time being, they guarantee a lot of chaos.
Whenever the federal government wants to build a new piece of infrastructure — and to some degree, whenever it wants to do anything significant — it has to go through NEPA. That sounds great in theory, but NEPA studies — which were originally meant to be just a few pages long — have now swelled in length, running into the thousands of pages and taking years to complete. They have become the subject of criticism from conservatives and some liberals.
That’s because NEPA doesn’t actually require the government to take the most environmentally friendly action. It only mandates that the government study the alternatives and arrive at a decision. Many critics, including progressives, now argue that NEPA has become a great bulwark of the status quo — a way for wealthy NIMBYs to slow down and block virtually any project they don’t like, including the large-scale solar, wind, and transmission projects necessary for the energy transition.
Other progressives argue that NEPA still serves a purpose — that it’s the only way environmental groups can provide a check on factory farms, new federal construction projects, or other big pieces of infrastructure. They say Congress should reform NEPA by affirmatively expanding parts of the permitting regime, adding new requirements to the process. The NEPA process is so time-consuming today not because it has become unwieldy, they say, but because the federal government does not employ enough civil servants to conduct the required studies on time. (NEPA’s critics reply to this, in essence: Sure, but why does NEPA require all those studies in the first place?)
At the heart of the case is a small federal agency called the Council on Environmental Quality. Since its creation in 1970, the Council on Environmental Quality has issued guidelines about how federal agencies should comply with NEPA. These rules have been treated as legally binding — that is, quasi-law on the same tier as federal regulation — since at least 1977.
In the ensuing decades, presidents from both parties have acted under the impression that the Council on Environmental Quality’s NEPA rules are binding. That’s why the first Trump administration went through the hassle of rewriting the council’s rules, subjecting them to the same notice-and-comment process other federal regulations must go through before they can be changed. The Biden administration later replaced the Trump administration’s rules with its own version.
But that actually isn’t the case, the judges ruled. The Council on Environmental Quality was never allowed to issue binding regulations about NEPA in the first place, they decided.
The Council on Environmental Quality can issue guidelines about how agencies should follow NEPA, the judges said. But these will have the same legal authority as executive orders, which can guide agency decisionmaking but provide no outside legal recourse. Executive orders are sort of like internal corporate policies for the government: They’re supposed to be followed by employees, but nobody can appeal to a court that a company got them wrong. What the council cannot do, the court said, is issue rules, quasi-laws that outside groups can appeal to and claim aren’t being obeyed in court.
If upheld, the ruling would throw virtually the entire body of law around NEPA into question — hundreds of cases, thousands of pages of rules, and hundreds of thousands of analyses all premised on the idea that the Center on Environmental Quality is the final NEPA arbiter. It could also vastly weaken NEPA, allowing the government to build projects quickly while giving Americans and nonprofit groups little recourse to stop them.
“It’s a very big deal,” James Coleman, an energy law professor at the University of Minnesota, told me. “NEPA by itself is a very limited piece of text. When it was adopted, no one imagined that it would lead to this comprehensive permitting system where it would take five years to get a permit.”
Over time, court cases and White House regulations have turned NEPA into the juggernaut that it is today. But now that’s exactly what is up in the air — potentially. “If a judge thinks that the decades of cases we’ve had are misconceived, then they don’t have to follow it any more,” Coleman said.
What’s odd about the case is that neither side intended to get this ruling in the first place. Neither the Federal Aviation Administration nor the Marin Audubon Society, a San Francisco-area birding group, set out to strike down the entire body of NEPA regulations. The FAA had relied on the Council on Environmental Quality’s rules when it approved a plan for tourism flights over national parks, saying that the regulations didn’t require it to conduct a NEPA study. The Marin Audubon Society argued that the air tours didn’t fall under an exemption created by the rules.
Two Republican-appointed judges on the panel then essentially took the case into their own hands, using the dispute as an opportunity to throw modern NEPA procedure into question. In fact, they said, the Council on Environmental Quality never had the authority to issue rules in the first place — so the claimed exemption didn’t matter. (Judge Sri Srinivasan, who dissented from part of the ruling, criticized the judges for opening such big legal questions when they didn’t need to do so.)
The outcome doesn’t mean that the federal government will immediately move faster to approve infrastructure projects — in some cases, it might move slower. As part of its rules, the Council on Environmental Quality has approved a list of “categorical exclusions,” federal actions that do not require a NEPA review. These can include activities like holding a small meeting or taking out a federal farm loan. The judges have now rejected the council’s ability to create categorical exclusions altogether, meaning that many more federal actions may — at least at first — be subject to NEPA oversight. (Congress has also told agencies to create some categorical exclusions — including for oil and gas drilling — and those are not affected by the case.)
For that reason, some environmental lawyers are doubtful that the argument will change NEPA in the way its opponents hope. “What the ruling does is deeply complicate things for both sides,” Sam Sankhar, the senior vice president at Earthjustice, an environmental legal group, told me. “The NEPA regulations are a body of law that has developed over years to guide the way that people do the NEPA process. The absence of those regulations does not mean the absence of NEPA — it means the absence of any guidelines about how to implement NEPA in the future.”
If the NEPA regulations get tossed out, he said, then it will “really be up to each individual judge to wing it” when interpreting the law, he added.
Nicholas Bagley, a University of Michigan law professor who has written critically about NEPA and other liberal laws that focus on procedure, tends to agree with that view. “When you go to court, agencies and challengers both would look at these regulations as a sword or a shield,” he said. Challengers used the White House rules as a weapon, asserting that the government needed to look at some question but failed to do so. But the federal government used those same rules “as a shield,” he said, showing that it faithfully followed the rules, and therefore that judges didn’t need to get involved.
If the rules are gone, then each side has lost a tool — and judges will have much more power. That means federal agencies, which are hesitant to run afoul of the courts, may now become even more timid in their decision-making, Bagley said. What’s more, the White House’s regulations would still act as executive orders, binding agency action. “They just won’t be enforceable in court,” he said. (The Trump administration could also respond by chucking out the White House regulations altogether, he said.)
It’s unclear what happens next. If the FAA appeals, the D.C. Circuit could choose to hear the case again en banc, meaning the full panel of judges — a majority of whom were appointed by Democrats — would consider the questions. But eventually a higher court may weigh in. “I would not be surprised at all to find this eventually find its way to the Supreme Court,” Coleman told me. In the past, the Supreme Court has ruled that the Council on Environmental Quality’s regulations carry the force of law. But the new, arch-conservative court — and the incoming Trump administration — might push for a different approach.

We knew the revived Chevrolet Bolt might have a limited run. Nobody knew it would be this limited.
General Motors began manufacturing the updated version of its small electric car late last year to begin deliveries this month. Already the news of its potential demise is here. GM says the Kansas factory that’s churning out Bolts will be repurposed to make combustion cars, including a Buick, of all things. Now, just as the arrival of the sub-$30,000 Bolt heralded a new age of more affordable electric cars, Chevy is dropping out of the race and putting its beloved little electric car on the backburner. Again.
The culprits in this case are clear. With the federal tax credit for buying EVs dead and gone, and with weakened emissions rules removing the incentive for car companies to pursue an aggressive electrification strategy, automakers are running back to the familiar embrace of fossil fuels. GM has already said it expects to lose billions as it adjusts its business strategy, curbing its EV push to meet the new reality under President Trump, where gas-burning cars remain much more profitable to build and sell.
The Bolt’s fate is the immediate fallout from that move. The Buick Envision, part of America’s army of indistinguishable gas-powered crossovers, had been built at a GM plant in China. Trump’s tariffs, however, incentivized the company to move production back to the U.S. The fact that GM repatriated the Envision at the expense of the Bolt tells you what you need to know about this moment in the U.S. auto market.
GM never promised that the Bolt would be back for good, and its return to limbo is par for the course when it comes to this plucky little car. The original Bolt EV had its problems, including a battery recall and glacial charging speeds by today’s standards. But the Bolt established GM’s place in the new EV age and found a flock of fans. At the time it was discontinued in 2023, it was the top-selling non-Tesla EV in America, selling more than 60,000 cars that year.
Fans clamored to get the car back. GM listened, and built a new version on the Ultium platform that forms the basis of its current generation of EVs. When I attended Chevy’s big reveal party for the new Bolt last year, it handed out merch reading “back by popular demand.” Yet GM always referred to the vehicle’s revival as a special run, as if not to get anyone’s hopes up that the Bolt would become a mainstay in the Chevy lineup.
Things could have been different, of course. GM has hinted at the possibility of expanding upon the Bolt with more models if the car succeeded in helping the company win the affordable EV race. Instead, the Kansas factory will turn back to combustion next year as Chevy builds some gas-powered Equinox SUVs there, moving production from Mexico after getting hammered by new tariffs. The Buick Envision, which GM has been making in China for nearly a decade, will begin Kansas production in 2028.
The Bolt’s second sudden death is a big blow to American EV lovers. Without a $7,500 tax break for buying an electric vehicle, Americans badly need more affordable options. Bolt, which starts around $29,000 in its most basic form, was set to lead a pack that would include other 2026 arrivals such as the customizable, Jeff Bezos-backed Slate truck and the reimagined third-generation Nissan Leaf. Now, you’d better act fast if you want to get behind the wheel of a Bolt.
Practically every week brings a flood of climate tech funding news and announcements — startups raising a new round, a venture capital firm closing a fresh fund, and big projects hitting (and missing) milestones. Going forward, I’ll close out each week with a roundup of some of the biggest stories that I didn’t get a chance to cover in full.
This week, we’ve got money for electric ships, next-gen geothermal, and residential electrification in Europe. Yay!
Many say battery-powered cargo ships will never make sense — that batteries are too heavy, too bulky, and would take up too much valuable space. FleetZero says it can make it work. Last Friday, the electric shipping startup raised a $43 million Series A round led by Obvious Ventures, with participation from other firms including Maersk Growth, the shipping giant’s corporate venture arm, and Breakthrough Energy Ventures. The funding will support production of the company’s hybrid and electric propulsion systems, as well as new manufacturing and R&D operations in Houston.
Ships’ bunker fuel is extremely polluting. It accounts for roughly 3% of global CO2 emissions and dirties the air with other pollutants such as sulfur and nitrogen oxides. Most players in the shipping decarbonization space want to shift to liquid fuels such as e-ammonia or e-methanol — a move that would require mulit-million-dollar engine overhauls and retrofits. FleetZero says that battery electrification will prove to be cheaper and simpler. The company is building batteries large enough to hybridize — and potentially one day fully electrify — large container ships.
As FleetZero’s CEO and co-founder Steven Henderson told my colleague Robinson Meyer on a 2024 episode of Heatmap’s Shift Key podcast, batteries are a relatively simple maritime decarbonization solution because “you can use existing infrastructure and build on it. You don’t need a new fundamental technology to do this.” And while the company has yet to provide any cost estimates for electrifying commercial shipping, as Henderson put it, “the numbers to do this are not outside the realm of possibility.”
The next-generation geothermal startup Sage Geosystems announced on Wednesday that it raised a $97 million Series B round, co-led by the renewable energy company Ormat Technologies and the growth equity firm Carbon Direct Capital. This came atop a hot week for geothermal overall. As I wrote already, the artificial intelligence-powered geothermal developer Zanskar announced a $115 million Series C round for its pursuit of AI-driven conventional geothermal, while Axios reported that the geothermal unicorn Fervo Energy has filed for an IPO.
Like Fervo, Sage uses drilling technology adapted from the oil and gas industry to create its own artificial reservoirs in hot, dry rock. The startup then pumps these fractures full of water, where it absorbs heat from the surrounding rocks before being brought to the surface as steam that’s used to generate electricity. Sage’s CEO, Cindy Taff — a former Shell executive — told Bloomberg that this latest investment will accelerate the company’s project timeline by a full year or two, allowing the company to put power on Nevada’s grid sometime in 2027.
This latest funding follows Sage’s strategic partnership with Ormat, announced last year, and could help the startup make good on its agreement with Meta to deliver up to 150 megawatts of clean electricity for the tech giant’s data centers starting in 2027.
Berlin-based startup Cloover — which helps Europeans finance home electrification upgrades — announced a $22 million Series A round on Wednesday, alongside a $1.2 billion debt facility from an unnamed “leading European bank” that it can draw on. The company, which describes itself as both the “operating system for energy independence” and the “Shopify of Energy,” aims to help homeowners ditch fossil fuels by facilitating loans to cover the upfront cost of, say, buying and installing heat pumps, rooftop solar, or home batteries — something traditional banks struggle to finance.
Cloover’s a fintech platform allows home energy installers to manage complex projects while offering loans for green upgrades to customers at the point of sale. The software’s AI-driven credit underwriting evaluates not just a customer’s credit score, but also the projected energy savings and performance of the upgrade itself, helping align the price and terms of borrowing with the anticipated economic value of the asset.
Forbes reports that Cloover has already financed roughly 2,500 home energy installations. The company says it’s profitable, generating nearly $100 million in sales last year. With this new funding, the startup plans to expand across Europe and is projecting $500 million in sales this year, anticipating an explosion in demand for distributed energy resources.
One of the oldest players in the race to commercialize fusion energy, General Fusion, has been candid about its recent funding struggles, laying off 25% of its staff last spring while publicly pleading for more cash. This Thursday, it announced a lifeline: a SPAC merger that will provide the company with up to $335 million, if all goes according to plan. Read more about the deal in our Heatmap AM newsletter.
Current conditions: The monster snow storm headed eastward could dump more than a foot of snow on New York City this weekend • An extreme heat wave in Australia is driving temperatures past 104 degrees Fahrenheit • In northwest India, Jammu and Kashmir are bracing for up to 8 inches of snow.
Last month, Fervo Energy raised another $462 million in a Series E round to finance construction of the next-generation geothermal startup’s first major power plant. Pretty soon, retail investors will be able to get in on the hype. On Thursday, Axios reported that the company had filed confidential papers with the Securities and Exchange Commission in preparation for an initial public offering. Fervo’s IPO will be a milestone for the geothermal industry. For years, the business of tapping the Earth’s molten heat for energy has remained relatively small, geographically isolated, and dominated by incumbent players such as Ormat Technologies. But Fervo set off a startup boom when it demonstrated that it could use fracking technology to access hot rocks in places that don’t have the underground reservoirs that conventional geothermal companies rely upon. In yesterday’s newsletter, I told you about how Zanskar, a startup using artificial intelligence to find more conventional resources, and Sage Geosystems, a rival next-generation company to Fervo, had raised a combined $212 million. But as my colleague Matthew Zeitlin wrote in December when Fervo raised its most recent financing round, it’s not yet clear whether the company’s “enhanced” geothermal approach is price competitive. With how quickly things are progressing, we will soon find out.
Fervo isn’t the only big IPO news. General Fusion, the Canadian fusion energy startup TechCrunch describes as “struggling,” announced plans for a $1 billion reverse merger deal to go public on the Nasdaq. The move comes almost exactly a month after President Donald Trump’s social media company, the parent firm of Truth Social, inked a deal to merge with the fusion startup TAE Technologies and create the first publicly-traded fusion company in the U.S. Analysts I spoke to about the deal called it “flabberghasting,” and warned that TAE’s technology represented a more complex and dubious approach to commercializing fusion than that taken by rival companies such as Commonwealth Fusion Systems. Still, the IPO deals highlight the growing excitement over progress on generating power from a technology long mocked as the energy source of tomorrow that always will be. As Heatmap’s Katie Brigham artfully put it in 2024, “it is finally, possibly, almost time for fusion.”
General Motors plans to move manufacturing of the next generation of its Buick Envision SUV from China to the U.S. in two years and end production of the all-electric Chevrolet Bolt. The Detroit auto giant makes just one of its four SUV models in the U.S., leaving the cars vulnerable to Trump’s tariffs. The worst hit was the Envision, which is currently built in China. Starting in 2028, the latest version of the Envision will be produced in Kansas, taking over the assembly line that is currently churning out the Bolt.
It's a blow to GM's electric vehicle line. Chevy just brought back the Bolt in response to high demand after initially canceling production in 2023, because as Andrew Moseman put it in Heatmap, it's “the cheap EV we've needed all along.” While Chevy had always framed the return as a limited run, it was not previously clear how limited that would be.

The Department of Energy said Thursday its newly rebranded Office of Energy Dominance Finance, formerly the Loan Programs Office, is “restructuring, revising, or eliminating more than $83 billion in Green New Scam loans and conditional commitments.” The move comes after “an exhaustive first-year review” of the $104 billion in principal loan obligations the Biden administration shelled out, including $85 billion the Trump administration accused of being “rushed out the door in the final months after Election Day.” In a statement, Secretary of Energy Chris Wright said the changes are meant to “ensure the responsible investment of taxpayer dollars.” While it’s not yet clear which projects are affected, the agency said the EDF eliminated about $9.5 billion in support for wind and solar projects and redirected that funding to natural gas and nuclear energy. But as Heatmap’s Emily Pontecorvo noted last night, the Energy Department hasn’t yet said which loans are set to be canceled as part of the latest cuts. The announcement may include loans that have already been canceled or restructured.

If you know anything about surging electricity demand, you’re likely to finger a single culprit: data centers. But worldwide, air conditioning dwarfs data centers as a demand driver. And in California, electric vehicles are on pace to edge out data centers as a bigger driver of peak demand on the grid. That’s according to a new report from the California Energy Commission. Just look at this chart:

As the Golden State tries to get a grip on its electricity system, Representative Ro Khanna, the progressive Silicon Valley congressman often discussed as a potential 2028 presidential candidate, has doubled down on his calls to break up the state’s largest utility. On Thursday, Khanna posted on X that PG&E “should be broken up and owned by customers, not shareholders. They are ripping off Californians by buying off politicians in Sacramento.” The Democrat has been calling for PG&E’s demise since at least 2019, when the utility was on the hook for billions of dollars in damages from a wildfire sparked by its equipment. But the idea hasn’t exactly caught on.
New energy technologies such as batteries, solar panels, and wind turbines are driving demand for minerals and spurring a controversial push for new mines on virgin lands. But a new study by researchers at the University of Queensland’s Sustainable Minerals Institute found that a production boom is already underway at existing mines. The peer-reviewed paper, which is the first comprehensive global analysis of brownfield mining expansion, found that existing mines are growing in size and scale. Just because the mines are already there doesn’t mean the new production doesn’t come with some social cost. Nearly 78% of the 366 mines analyzed in the study “are located in areas facing multiple high-risk socioeconomic conditions, including weak governance, poor corruption control, and limited press freedom,” the study found.
The Department of the Interior has a new coal mascot. On Thursday, the agency posted an animated picture of a cartoonish, rosy-cheeked, chicken nugget-shaped lump of coal clad in a yellow hardhat and construction gear. His name? Coalie. The idea isn’t original. Australia’s coal-mining trade group rolled out an almost identical mascot a few years ago — same anthropomorphic lump of coal, same yellow attire. The only difference? His name was Hector, and he wore glasses.
