From what it means for America’s climate goals to how it might make American cars smaller again
The Biden administration just kicked off the next phase of the electric-vehicle revolution.
The Environmental Protection Agency unveiled Wednesday some of the world’s most aggressive climate rules on the transportation sector, a sweeping effort that aims to ensure that two-thirds of new cars, SUVs, and pickups — and one-quarter of new heavy-duty trucks — sold in the United States in 2032 will be all electric.
The rules, which are the most ambitious attempt to regulate greenhouse-gas pollution in American history, would put the country at the forefront of the global transition to electric vehicles. If adopted and enforced as proposed, the new standards could eventually prevent 10 billion tons of carbon pollution, roughly double America’s total annual emissions last year, the EPA says.
The rules would roughly halve carbon pollution from America’s massive car and truck fleet, the world’s third largest, within a decade. Such a cut is in line with Biden’s Paris Agreement goal of cutting carbon pollution from across the economy in half by 2030.
Transportation generates more carbon pollution than any other part of the U.S. economy. America’s hundreds of millions of cars, SUVs, pickups, 18-wheelers, and other vehicles generated roughly 25% of total U.S. carbon emissions last year, a figure roughly equal to the entire power sector’s.
In short, the proposal is a big deal with many implications. Here are seven of them.

Every country around the world must cut its emissions in half by 2030 in order for the world to avoid 1.5 degrees Celsius of temperature rise, according to the Intergovernmental Panel on Climate Change. That goal, enshrined in the Paris Agreement, is a widely used benchmark for the arrival of climate change’s worst impacts — deadly heat waves, stronger storms, and a near total die-off of coral reefs.
The new proposal would bring America’s cars and trucks roughly in line with that requirement. According to an EPA estimate, the vehicle fleet’s net carbon emissions would be 46% lower in 2032 than they stand today.
That means that rules of this ambition and stringency are a necessary part of meeting America’s goals under the Paris Agreement. The United States has pledged to halve its carbon emissions, as compared to its all-time high, by 2020. The country is not on track to meet that goal today, but robust federal, state, and corporate action — including strict vehicle rules — could help it get there, a recent report from the Rhodium Group, an energy-research firm, found.

Until this week, California and the European Union had been leading the world’s transition to electric vehicles. Both jurisdictions have pledged to ban sales of new fossil-fuel-powered cars after 2035 and set aggressive targets to meet that goal — although Europe recently watered down its commitment by allowing some cars to burn synthetic fuels.
The United States hasn’t issued a similar ban. But under the new rules, its timeline for adopting EVs will come close to both jurisdictions — although it may slightly lag California’s. By 2030, EVs will make up about 58% of new vehicles sold in Europe, according to the think tank Transportation & Environment; that is roughly in line with the EPA’s goals.
California, meanwhile, expects two-thirds of new car sales to be EVs by the same year, putting it ahead of the EPA’s proposal. The difference between California’s targets and the EPA’s may come down to technical accounting differences, however. The Washington Post has reported that the new EPA rules are meant to harmonize the national standards with California’s.

With or without the rules, the United States was already likely to see far more EVs in the future. Ford has said that it would aim for half of its global sales to be electric by 2030, and Stellantis, which owns Chrysler and Jeep, announced that half of its American sales and all its European sales must be all-electric by that same date. General Motors has pledged to sell only EVs after 2035. In fact, the EPA expects that automakers are collectively on track for 44% of vehicle sales to be electric by 2030 without any changes to emissions rules.
But every manufacturer is on a different timeline, and some weren’t planning to move quite this quickly. John Bozella, the president of Alliance for Automotive Innovation, has struck a skeptical note about the proposal. “Remember this: A lot has to go right for this massive — and unprecedented — change in our automotive market and industrial base to succeed,” he told The New York Times.
The proposed rules would unify the industry and push it a bit further than current plans suggest.

The EPA’s proposal would see sales of all-electric heavy trucks grow beginning with model year 2027. The agency estimates that by 2032, some 50% of “vocational” vehicles sold — like delivery trucks, garbage trucks, and cement mixers — will be zero-emissions, as well as 35% of short-haul tractors and 25% of long-haul tractor trailers. This would save about 1.8 billion tons of CO2 through 2055 — roughly equivalent to one year’s worth of emissions from the transportation sector.
But the proposal falls short of where the market is already headed, some environmental groups pointed out. “It’s not driving manufacturers to do anything,” said Paul Cort, director of Earthjustice’s Right to Zero campaign. “It’s following what’s happening in the market in a very conservative way.”
Last year, California passed rules requiring 60% of vocational truck sales and 40% of tractors to be zero-emissions by 2032. Daimler, the world’s largest truck manufacturer, has said that zero emissions trucks would make up 60% of its truck sales by 2030 and 100% by 2039. Volvo Trucks, another major player, said it aims for 50% of its vehicle deliveries to be electric by 2030.

One of the more interesting aspects of the new rules is that they pick up on a controversy that has been running on and off for the past 13 years.
In 2010, the Obama administration issued the first-ever greenhouse-gas regulations for light-duty cars, SUVs, and trucks. In order to avoid a Supreme Court challenge to the rules, the White House did something unprecedented: It got every automaker to agree to meet the standards even before they became law.
This was a milestone in the history of American environmental law. Because the automakers agreed to the rules, they were in effect conceding that the EPA had the legal authority to regulate their greenhouse-gas pollution in the first place. That shored up the EPA’s legal authority to limit greenhouse gases from any part of the economy, allowing the agency to move on to limiting carbon pollution from power plants and factories.
But that acquiescence came at a cost. The Obama administration agreed to what are called “vehicle footprint” provisions, which put its rules on a sliding scale based on vehicle size. Essentially, these footprint provisions said that a larger vehicle — such as a three-row SUV or full-sized pickup — did not have to meet the same standards as a compact sedan. What’s more, an automaker only had to meet the standards that matched the footprint of the cars it actually sold. In other words, a company that sold only SUVs and pickups would face lower overall requirements than one that also sold sedans, coupes, and station wagons.
Some of this decision was out of Obama’s hands: Congress had required that the Department of Transportation, which issues a similar set of rules, consider vehicle footprint in laws that passed in 2007 and 1975. Those same laws also created the regulatory divide between cars and trucks.
But over the past decade, SUV and truck sales have boomed in the United States, while the market for old-fashioned cars has withered. In 2019, SUVs outsold cars two to one; big SUVs and trucks of every type now make up nearly half the new car market. In the past decade, too, the crossover — a new type of car-like vehicle that resembles a light-duty truck — has come to dominate the American road. This has had repercussions not just for emissions, but pedestrian fatalities as well.
Researchers have argued that the footprint rules may be at least partially to blame for this trend. In 2018, economists at the University of Chicago and UC Berkeley argued Japan’s tailpipe rules, which also include a footprint mechanism, pushed automakers to super-size their cars. Modeling studies have reached the same conclusion about the American rules.
For the first time, the EPA’s proposal seems to recognize this criticism and tries to address it. The new rules make the greenhouse-gas requirements for cars and trucks more similar than they have been in the past, so as to not “inadvertently provide an incentive for manufacturers to change the size or regulatory class of vehicles as a compliance strategy,” the EPA says in a regulatory filing.
The new rules also tighten requirements on big cars and trucks so that automakers can’t simply meet the rules by enlarging their vehicles.
These changes may not reverse the trend toward larger cars. It might even reveal how much cars’ recent growth is driven by consumer taste: SUVs’ share of the new car market has been growing almost without exception since the Ford Explorer debuted in 1991. But it marks the first admission by the agency that in trying to secure a climate win, it may have accidentally created a monster.

The EPA is trumpeting the energy security benefits of the proposal, in addition to its climate benefits.
While the U.S. is a net exporter of crude — and that’s not expected to change in the coming decades — U.S. refineries still rely on “significant imports of heavy crude which could be subject to supply disruptions,” the agency notes. This reliance ties the U.S. to authoritarian regimes around the world and also exposes American consumers to wilder swings in gas prices.
But the new greenhouse gas rules are expected to severely diminish the country’s dependence on foreign oil. Between cars and trucks, the rules would cut crude oil imports by 124 million barrels per year by 2030, and 1 billion barrels in 2050. For context, the United States imported about 2.2 billion barrels of crude oil in 2021.
This would also be a turning point for gas stations. Americans consumed about 135 billion gallons of gasoline in 2022. The rules would cut into gas sales by about 6.5 billion gallons by 2030, and by more than 50 billion gallons by 2050. Gas stations are going to have to adapt or fade away.

Although it may seem like these new electric vehicles could tax our aging, stressed electricity grid, the EPA claims these rules won’t change the status quo very much. The agency estimates the rules would require a small, 0.4% increase in electricity generation to meet new EV demand by 2030 compared to business as usual, with generation needs increasing by 4% by 2050. “The expected increase in electric power demand attributable to vehicle electrification is not expected to adversely affect grid reliability,” the EPA wrote.
Still, that’s compared to the trajectory we’re already on. With or without these rules, we’ll need a lot of investment in new power generation and reliability improvements in the coming years to handle an electrifying economy. “Standards or no standards, we have to have grid operators preparing for EVs,” said Samantha Houston, a senior vehicles analyst at the Union of Concerned Scientists.
The reduction in greenhouse gas emissions from replacing gas cars will also far outweigh any emissions related to increased power demands. The EPA estimates that between now and 2055, the rules could drive up power plant pollution by 710 million metric tons, but will cut emissions from cars by 8 billion tons.

How the perpetually almost-there technology could get shut out of the Inflation Reduction Act’s surviving nuclear tax credits.
The House offered a last minute olive branch to the increasingly bipartisan nuclear industry when it passed its version of the budget reconciliation bill now working its way through the Senate, opting to preserve tax credit eligibility for so-called “advanced nuclear facilities” that start construction by 2029. That deadline will be difficult for many nuclear companies to meet, regardless of their technological approach or reactor size. But one much anticipated, potentially world-changing technology won’t even have a shot: nuclear fusion.
That’s not because fusion is so futuristic that the 2029 deadline would be categorically unworkable. As I keep hearing, the tech is finally, possibly, actually on the verge of commercialization, and some industry leaders such as Commonwealth Fusion Systems could probably break ground on a commercial reactor by then.
Fusion won’t have a shot simply because, as defined by Congress and the IRS, it does not fall within the category of an “advanced nuclear facility.” Instead, it’s defined and regulated as a separate class of zero-emission technology, thus excluding it from the nuclear carve out in the budget bill. That distinction was made clear in January, when the IRS released its final regulations for the Inflation Reduction Act, Julien Barber, an investor in multiple fusion technologies at Emerson Collective, told me. That separation happened because “we wanted to regulate them differently,” he said.
Fusion reactors can’t melt down and don’t produce the kind of highly radioactive nuclear waste that fission does, meaning that many of the safety constraints on conventional nuclear don’t apply to fusion. In 2023, the Nuclear Regulatory Commission decided to regulate fusion reactors more like particle accelerators, which are typically licensed at the state level, have fewer siting constraints, less stringent security requirements, and are often exempt from full environmental review. Last year, a bipartisan group of senators worked together to pass the Fusion Energy Act, which confirmed the NRC’s decision to separate the regulatory processes.
If the Senate approves the House’s version of the clean energy investment and production tax credits, fusion energy will be subject to the same tight restrictions as other clean energy solutions. The timeline for credit eligibility requires energy projects to begin construction a mere 60 days after the bill’s passage, and be placed in service by 2029. That, Barber said, is “essentially impossible for any of the fusion companies out there.” Brian Berzin, CEO of the fusion startup Thea Energy, agreed. “Most private fusion companies will be left unable to benefit from these financial incentives,” he wrote in an emailed statement.
There’s confusion, however, around whether this fusion exclusion was a deliberate decision from the House or simply an oversight. Barber is betting on the latter.
“This was happening quickly,” Barber told me. “There was some push by some of the companies in the [Fusion Industry Association] to review the language, but they just didn’t have time to review the language in time to write comments, and it just kind of got pushed through as is.”
The bill’s final language also took the CEO of the Fusion Industry Association, Andrew Holland, by surprise. “We had heard that fusion would be part of the carve out too, but then it wasn’t,” Holland told me.
A more pessimistic interpretation is also possible, Barber conceded. “There’s the idea that people don’t think fusion is ever going to be the case,” he told me. Certainly for some both in and out of government, fusion represents a dream perpetually deferred.
What Barber thinks many people fail to realize, though, is that some fusion industry leaders are operating on timelines similar to fission companies building small modular reactors. “If you talk to CFS, they’re going to say, We’re going to be putting our first power plant on the grid by the early 2030s, which is the same timeline as [small modular reactor company] X-energy, right?”
Until this moment, the distinction that top governing bodies such as the Nuclear Regulatory Commission have made between fusion and fission has been nothing but a positive for fusion companies and advocates alike. When the Fusion Energy Act passed, one of the bill’s co-sponsors, Republican John Cornyn of Texas, said that “fusion energy is a promising clean and safe power source that could help address America’s growing energy demands.” Another co-sponser, Republican Todd Young of Indiana, said that fusion “has the potential to usher in a new era of energy production in America.”
But whether generalized Republican support for fusion will extend beyond easing regulations to actively include subsidies for the technology remains to be seen. And for now, most of the companies themselves are staying quiet. As of publication time, CFS, Zap Energy, Type One Energy, and Xcimer Energy all either said they could not comment or else did not respond to my request for comment.
Editor’s note: This story has been updated to include comments from the Fusion Industry Association.
Regardless of who’s eligible for what and when, strict “foreign entity of concern” provisions could make clean energy incentives impossible to take advantage of.
The word of the moment in renewable energy is “unworkable.” That’s how the chief executives of two major renewables developers — John Ketchum of NextEra and Jim Murphy of Invenergy — described new requirements inserted into clean energy tax credits by congressional Republicans in recent weeks.
“The way they’re drafted, they’re unworkable,” Ketchum said of the requirements at a Politico summit held earlier this week. He was referring specifically to a new set of provisions in the House budget reconciliation bill which say that to qualify for the credits, companies must divest their supply chains from “foreign entities of concern,” a group of countries comprising Russia, Iran, North Korea, and China. But really, the rules are about China.
Around 80% of the global solar panel supply chain runs through China, according to the International Energy Agency. The batteries used in many stationary storage systems are almost entirely made in China, to name just a couple isolated examples. Starting in 2026, the bill mandates that developers seeking to claim the clean energy production or investment tax credits may not receive “material assistance” from China. That refers to any component or subcomponent (including critical minerals) that was “extracted, processed, recycled, manufactured, or assembled” by a “prohibited foreign entity,” defined as a company with at least 25% Chinese ownership or 10% Chinese debt holdings, according to a memo by the law firm Norton Rose Fulbright. The rules become even more strict in 2028. Similar strictures were also added to the 45X advanced manufacturing tax credit.
A small modular reactor has at least 10,000 component parts, Ketchum told the Politico audience. “We come to find out that one of the screws in the bolts, used by one of the suppliers five layers down … was actually sourcing the bolt and the screw from China. Guess what happens? You’re disqualified, all your tax credits for that small modular reactor go away,” Ketchum said.
“How in the world are you going to trace five layers down to a subcontractor who’s buying a bolt and a screw?”
Murphy, the Invenergy CEO, put it more succinctly at an industry conference last week. “The supply chain can not support that, and won’t be able to support that for several years. It’s just an unworkable provision.”
While these may sound like the exaggerations of executives eager to avoid paperwork or costly new investments, analysts who have looked at the bill’s language have similarly concluded that the language is both so vague and so broad that determining whether a company has complied would be almost impossible.
Analysts at the investment bank Evercore wrote in a note to clients last week that while the new FEOC framework “ostensibly aims to keep China out of U.S. energy supply chains, it would likely bury companies and their suppliers in such onerous paperwork and diligence that the remaining tax credits are rendered largely unusable.”
Foreign entity of concern rules are not new — versions of them appear in the CHIPS and Science Act and the Inflation Reduction Act’s electric vehicle tax credits. The FEOC rules in the One Big, Beautiful Bill are far more extensive, however.
The Senate may look to loosen the rules, according to Axios, andseveral House Republicans have signed (yet another) letter, this one referring to the restrictions as “highly restrictive and onerous” and “overly prescriptive and risk undermining U.S. competitiveness.”
Should the FEOC provisions become law, their exact implementation will be up to the IRS. In the case of EVs, the tax agency came out with proposed guidelines in the months after the Inflation Reduction Act was enacted, but didn’t finalize them until 2024. Even complying with those required a “Herculean” effort from the EV and battery industry, Albert Gore, head of the Zero Emission Transportation Association, told me.
Gore also questioned whether the rules would be “workable” as written. To determine whether compliance would be worth it, Gore said, you have to evaluate how close an industry is to complying in the present, and the value of complying in the future, and the cost to get there.
Given that the clean energy and manufacturing credits sunset after 2031 (except for wind components, which sunset earlier), that calculation may very well come out negative. And then there’s the deadline to even qualify for the clean energy tax credits in the first place, starting construction two months after the bill passes, according to the House language.
The EV rules did ultimately support U.S. manufacturing, Gore told me. “It was a pretty efficient investment in American manufacturing, kind of disguised as a consumer EV credit,” he said. “But it was a very, very stringent credit.”
Xan Fishman, senior managing director of the energy program at the Bipartisan Policy Center, was skeptical that the FEOC provisions in the budget reconciliation bill would do anything to bolster U.S. manufacturing. “Intricate and complicated doesn’t make it more effective,” he told me.
“You would have a disallowance of credit if you are a foreign entity of concern, or you are a foreign influenced entity of concern, which might mean that one of your suppliers is a foreign entity of concern, or one of your supplier’s board members is from China or they have a family member that’s from China that runs a foreign entity of concern, or that family member has some business transaction involving debt with a foreign entity of concern, and their suppliers actually might have board members who have family members who have some debt arrangement with the foreign entity of concern,” Fishman elaborated.
This is where workability really comes in.
“If the result of this is we have less U.S. manufacturing, we won’t have achieved the goal” of raising America’s global competitiveness. “Nor will we have been tough on China,” Fishman said.
The ironies of the legislation abound. “There's sort of that double whammy in there with the start of construction deadline, which to some extent, makes the FEOC moot,” Murphy, the Invenergy CEO, said at the conference. “If you don't start construction by the deadline, who cares about it?”
Ironically, if the Senate put in a more relaxed deadline to qualify for the credits, “then we have to really address those foreign entity of concern provisions,” Murphy added.
On Trump’s ‘windmill’ ban, FEMA turnover, and PNW power
Current conditions: Physical activity is “discouraged” at the Grand Canyon today as temperatures climb toward 110 degrees Fahrenheit • Tropical Storm Wutip could dump 7 inches of rain in six hours over parts of Vietnam • Investigators are looking into whether this week’s triple-digit heat in Ahmedabad, India, was a factor in Thursday’s deadly plane crash.

President Trump said Thursday that his administration is “not going to approve windmills unless something happens that’s an emergency.” The comments — made during the White House East Room signing of legislation overturning California’s authority to set its own car pollution standards — were Trump’s clearest confirmation yet of my colleague Jael Holzman’s reporting, which this week found that “the wind industry’s worst fears are indeed coming to pass.” As Jael went on in The Fight, the Fish and Wildlife Service and the U.S. Army Corps of Engineers have “simply stopped processing wind project permit applications after Trump’s orders — and the freeze appears immovable, unless something changes.”
Trump justified the pause by adding that “we’re not going to let windmills get built because we’re not going to destroy our country any further than it’s already been destroyed,” repeating his long-held grievance that “you go and look at these beautiful plains and valleys, and they’re loaded up with this garbage that gets worse and worse looking with time.” Trump’s aesthetic objections have already blocked at least three wind projects in New York alone — a move that has impacts beyond future energy generation, Jael further notes. According to the Alliance for Clean Energy New York, the policy has impacted “more than $2 billion in capital investments, just in the land-based wind project pipeline, and there’s significant reason to believe other states are also experiencing similar risks.” Read Jael’s full report here.
Turnover at the Federal Emergency Management Agency continued this week after the head of the National Response Coordination Center — responsible for overseeing the federal response to major storms — submitted his resignation, CBS News reported Thursday. Jeremy Greenberg, who’s worked various roles at FEMA for nearly a decade, will stay on for another two weeks but ultimately depart less than a month into hurricane season. “He’s irreplaceable,” one current FEMA official told CBS News, adding that “the brain drain continues and the public will pay for it.” Greenberg’s resignation follows comments President Trump made to the press earlier this week about the need to “wean off of FEMA” after hurricane season is over in November. “A governor should be able to handle” disaster response, the president told reporters on Tuesday, “and frankly, if they can’t handle it, the aftermath, then maybe they shouldn’t be governor.”
Also on Thursday, President Trump issued a presidential memorandum revoking a $1 billion Biden-era agreement to restore salmon and invest in tribally sponsored clean energy infrastructure in the Columbia River Basin, The Seattle Times reports. Biden’s agreement had “placed concerns about climate change above the nation’s interests in reliable energy sources,” the White House claimed.
The 2023 agreement resulted from three decades of opposition to the dams on the Lower Snake River by local tribes and environmental groups. While the Biden administration hadn’t committed to a dam removal, it did present a potential pathway to do so, since Washington State politicians have said that hydropower would need to be replaced by another power source before they’d consider a dam removal plan. The government’s billion-dollar investment would have aided in the construction of up to 3 gigawatts of alternative renewable energy in the region. Kurt Miller, the CEO of the Northwest Public Power Association, celebrated Trump’s action, saying, “In an era of skyrocketing electricity demand, these dams are essential to maintaining grid reliability and keeping energy bills affordable.” But Washington Senator Patty Murray, a Democrat, vowed to fight the “grievously wrong” decision, arguing, “Donald Trump doesn’t know the first thing about the Northwest and our way of life — so of course, he is abruptly and unilaterally upending a historic agreement.”
Two years after we wrote the eulogy for the Chevrolet Bolt EV — “the cheap little EV we need” — General Motors has announced that it will launch the second generation of the car for the 2027 model year. Though “no other details were provided about this next iteration of the Bolt,” Car and Driver wrote that “we expect it to continue as a tall subcompact hatchback, although it could be positioned as a subcompact SUV like the previous generation's EUV model.” A reveal could be coming in the next several months ahead of a likely on-sale date in mid-2026.
Energy developer Scale Microgrids announced Thursday that its latest round of financing, which closed at $275 million, has brought its total to date to over $1 billion. KeyBanc Capital Markets, Cadence Bank, and New York Green Bank led the round, with Greg Berman, the managing director in KeyBanc Capital Markets Utilities, saying in a statement, “We value our relationship with Scale and congratulate their team as they execute on their strategy to deliver high-quality distributed energy assets to the market.” Scale Microgrids said the financing will “support 140 megawatts of distributed generation projects, including microgrids, community-scale solar and storage, and battery storage installations,” many of which are already under construction in the Northeast and California.
“Our best chance is to get a group of critical mass of Republican senators to go to [Senate Majority Leader John] Thune and [Senate Finance Committee Chair Mike] Crapo and say, You’ve got to change this. We can’t vote for it the way it is.” —Democratic Majority Leader Chuck Schumer in conversation with Heatmap’s Robinson Meyer about the Senate math and strategy behind saving the Inflation Reduction Act.
