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.

A new “foreign entities of concern” proposal might be just as unworkable as the House version.
In the House’s version of Trump’s One, Big, Beautiful Bill Act Republicans proposed denying tax credits to clean energy companies whose supply chains contained any ties — big or small — to China. The rules were so administratively and logistically difficult, industry leaders said, that they were effectively the same as killing the tax credits altogether.
Now the Senate is out with a different proposal that, at least on its face, seems to be more flexible and easier to comply with. But upon deeper inspection, it may prove just as unworkable.
“It has the veneer of giving more specificity and clarity,” Kristina Costa, a Biden White House official who worked on Inflation Reduction Act implementation, told me. “But a lot of the fundamental issues that were present in the House bill remain.”
The provisions in question are known as the “foreign entities of concern” or FEOC rules. They penalize companies for having financial or material relationships with businesses that are “owned by, controlled by, or subject to the jurisdiction or direction of” any of four countries — Russia, Iran, North Korea, and, most importantly for clean energy technology, China.
The Inflation Reduction Act imposed FEOC restrictions on just one clean energy tax credit — the $7,500 consumer credit for electric vehicles. Starting in 2024, if automakers wanted their cars to qualify, they could not use battery components that were manufactured or assembled by a FEOC. The rules ratcheted up over time, later disallowing critical minerals extracted or processed by a FEOC.
The idea, Costa told me, was to “target the most economically important components and materials for our energy security and economic security.” But now, the GOP is attempting to impose FEOC restrictions liberally to every tax credit and every component, in a world where China is the biggest lithium producer and dominates roughly 80% of the solar supply chain.
Not only would sourcing outside China be challenging, it would also be an administrative nightmare. The way the House’s reconciliation bill was written, a single bolt or screw sourced from a Chinese company, or even a business partially owned by Chinese citizens, could disqualify an entire project. “How in the world are you going to trace five layers down to a subcontractor who’s buying a bolt and a screw?” John Ketchum, the CEO of the energy company NextEra, said at a recent Politico summit. Ketchum deemed the rules “unworkable.”
The Senate proposal would similarly attach FEOC rules to every tax credit, but it has a slightly different approach. Rather than a straight ban on Chinese sourcing, the bill would phase-in supply chain restrictions, requiring project developers and manufacturers to use fewer and fewer Chinese-sourced inputs over time. For example, starting next year, in order for a solar farm to qualify for tax credits, 40% of the value of the materials used to develop the project could not be tied to a FEOC. By 2030, the threshold would rise to 60%. The bill includes a schedule of benchmarks for each tax credit.
“That might be strict, but it’s clearer and more specific, and it’s potentially doable,” Derrick Flakoll, the senior policy associate for North America at BloombergNEF, told me. “It’s not an all or nothing test.”
But how companies should calculate this percentage is not self-evident. The Senate bill instructs the Treasury department to issue guidance for how companies should weigh the various sub-components that make up a project. It references guidance issued by the Biden administration for the purposes of qualifying for a domestic content bonus credit, and says companies can use this for the FEOC rules until new guidance is issued.
Mike Hall, the CEO of a company called Anza that provides supply chain data and analytics to solar developers, told me he felt that the schedule was achievable for solar farm developers. But the Biden-era guidance only contains instructions for wind, solar, and batteries. It’s unclear what a company building a geothermal project or seeking to claim the manufacturing tax credit would need to do.
Costa was skeptical that the Senate bill was, in fact, clearer or more specific than the House version. “They’re not providing the level of precision in their definitions that it would take to be confident that the effect of what they’re doing here will not still require going upstream to every nut, bolt, screw, and wire in a project,” she said.
It’s also hard to tell whether certain parts of the text are intentional or a drafting error. There’s a section that Flakoll had interpreted as a grandfathering clause to allow companies to exempt certain components from the calculation if they had pre-existing procurement contracts for those materials. But Costa said that even though that seems to have been the intent, the way that it’s written does not actually achieve that goal.
In addition to rules on sourcing, the Senate bill would introduce strict ownership rules that could potentially disqualify projects that are already under construction or factories that are already producing eligible components. The text contains a long list defining various relationships with Chinese entities that would disqualify a company from tax credits. Perhaps the simplest one is if a Chinese entity owns just 25% of the company.
BloombergNEF analyzed the pipeline of solar and battery factories that are operational, under construction, or have been announced in the U.S. as of March, and quite a few have links to China. The research firm identified 22 firms “headquartered in China with Chinese parent companies or majority-Chinese shareholders” that are behind more than 100 existing or planned solar or battery factories in the U.S.
One example is AESC, a Japanese battery manufacturer that sold a controlling stake in the business to a Chinese company in 2018. AESC has two gigafactories under construction in Kentucky and South Carolina, both of which are currently paused, and a third operating in Tennessee. Another is Illuminate USA, a joint venture between U.S. renewables developer Invenergy and Chinese solar panel manufacturer LONGi; it began producing solar panels at a new factory in Ohio last year. The sources I reached out to would not comment on whether they thought that Ford, which has a licensing deal with Chinese battery maker CATL, would be affected. Ford did not respond to a request for comment.
Hall told me he would expect to see Chinese companies try to divest from these projects. But even then, if the business is still using Chinese intellectual property, it may not qualify. “It’s just a lot of hurdles for some of these factories that are already in flight to clear,” he said.
In general, the FEOC language in the Senate bill was “still not good,” he said, but “a big improvement from what was in the House language, which just seemed like an insurmountable challenge.”
Albert Gore, the executive director of the Zero Emissions Transportation Association, had a similar assessment. “Of course, the House bill isn’t the only benchmark,” he told me. “Current law is, in my view, the current benchmark, and this is going to have a pretty negative impact on our industry.”
A statement from the League of Conservation Voters’ Vice President of Federal Policy Matthew Davis was more grave, warning that the Trump administration could use the ambiguity in the bill to block projects and revoke credits. “The FEOC language remains a convoluted, barely workable maze that invites regulatory chaos, giving the Trump administration wide-open authority to worsen and weaponize the rules through agency guidance,” he wrote.
On storm damage, the Strait of Hormuz, and Volkswagen’s robotaxi
Current conditions: A dangerous heat dome is forming over central states today and will move progressively eastward over the next week • Wildfire warnings have been issued in London • Typhoon Wutip brought the worst flooding in a century to China’s southern province of Guangdong.
Hurricane Erick made landfall as a Category 3 storm on Mexico’s Pacific coast yesterday with maximum sustained winds around 125 mph. Damages are reported in Oaxaca and Guerrero. The storm is dissipating now, but it could drop up to 6 inches of rain in some parts of Mexico and trigger life-threatening flooding and mudslides, according to the National Hurricane Center. Erick is the earliest major hurricane to make landfall on Mexico's Pacific coast, and one of the fastest-intensifying storms on record: It strengthen from a tropical storm to a Category 4 storm in just 24 hours, a pattern of rapid intensification that is becoming more common as the Earth warms due to human-caused climate change. As meteorologist and hurricane expert Michael Lowry noted, Mexico’s Pacific coast was “previously unfamiliar with strong hurricanes” but has been battered by epic storms over the last two years. Acapulco is still recovering from Category 5 Hurricane Otis, which struck in late 2023.

An oil tanker collision near the Strait of Hormuz is raising environmental and security concerns. The accident in the Gulf of Oman involved the Adalynn and Front Eagle tankers. It caused a “small oil spill,” according to the Emirati government, but Greenpeace analyzed satellite images and said the oil plume stretches some six square miles from the collision site. “This is just one of many dangerous incidents to take place in the past years,” said Greenpeace campaigner Farah Al Hattab. The Strait of Hormuz is a choke point for oil shipments, with about one-third of the volume of crude exported by sea moving through that route. Oil prices have been on a roller coaster ride since Israel launched airstrikes against Iran on June 13. Ships in the region have been reporting more GPS navigation interference in recent days. “If the conflict continues, we expect these interferences to continue as well,” Jean-Charles Gordon, senior director of ship tracking at research firm Kpler, toldThe New York Times.
North Carolina lawmakers finalized a bill repealing a mandate that directs electric regulators to reduce their carbon dioxide emissions by 70% by 2030. The mandate was part of a landmark 2021 law aimed at dramatically reducing the state’s power plant emissions. While at least 17 other states have similar laws in place, just two – North Carolina and Virginia – are in the Southeast. The new bill’s supporters say that the interim emissions goal would require energy providers to switch to more expensive power sources and that the costs would be passed on to consumers in the form of higher power bills.
Confusingly, regulators would still be asked to work toward carbon neutrality by 2050, even while the short-term emissions goal might be nixed. “Not having any target, even an aspirational target, could mean that we don’t stay on track to get to our 2050 goal,” Democratic Sen. Julie Mayfield said. The bill now goes to Democratic Gov. Josh Stein’s desk. There’s a chance he might veto it, but “with over a dozen House and Senate Democrats voting for the final version, the chances that any Stein veto could be overridden are higher,” The Associated Pressreported.
The United Kingdom issued long-awaited environmental guidance that it will use to determine whether new oil and gas proposals should be approved. The guidance requires that developers estimate and include scope 3 emissions – or the downstream pollution from burning oil and gas – in their drilling applications. This “will ensure the full effects of fossil fuel extraction on the environment are recognized in consenting decisions,” the Department for Energy Security and Net Zero said. The government will consider these emissions, as well as other factors like “the potential economic impact” of a project and a company’s efforts to remove carbon dioxide when granting or denying approval. The guidance will help determine whether major new drilling projects from oil giants Shell and Equinor are approved for the North Sea.
Volkswagen Group unveiled its first fully autonomous production vehicle, the ID. Buzz AD. The electric robotaxis will target corporate customers and mobility services. They “come packed with everything that’s needed to operate them,” explained Iulian Dnistran at InsideEVs. “What makes this solution interesting compared to other ride-hailing platforms is that it enables anybody to start an Uber or Waymo rival without investing hundreds of millions of dollars in research, development, and certification.” The shuttles are slated for launch across Europe and the U.S. next year. Tesla recently announced that its first Robotaxis would hit the streets in Austin, Texas, sometime this month.

In a new peer-reviewed paper published in the journal Communications Earth & Environment, researchers conclude that offsetting the potential carbon emissions from reserves held by the world’s 200 largest fossil fuel companies would require planting new forests that are larger than the entire continent of North America.
The energy secretary's philosophy is all over the Senate mega-bill.
As the Senate Finance Committee worked on its version of the reconciliation bill that would, among things, overhaul the Inflation Reduction Act, there was much speculation among observers that there could be a carve out for sources of power like geothermal, hydropower, and nuclear, which provide steady generation and tend to be more popular among Republicans, along the lines of the slightly better treatment received by advanced nuclear in the House bill.
Instead, the Senate Finance Committee’s text didn’t carve out these “firm” sources of power, it carved out solar and wind, preserving tax credits for everything else through 2035, while sunsetting solar and wind by 2028.
For much of the last few months — and for years before he was sworn in as Secretary of Energy — Chris Wright has been expounding on his philosophy of energy and climate. If anything, the Senate Finance draft seems to hew closer to Wright’s worldview than Trump’s, which is less specific, even more critical of renewables (especially wind), and largely in favor of nuclear power when it comes to non-carbon-emitting generation.
“I’m sure Secretary Wright’s strong support for firm technologies over the past few months played a role in Chairman Crapo’s approach to energy tax credit reform,” Pavan Venkatakrishnan, an infrastructure fellow at the Institute for Progress, told me.
Wright argues that climate change is real but not a top-tier concern and that it certainly should not be addressed by restricting energy usage, which he sees as foundational to the good life here and abroad.
And among energy sources, the former fracking executive is no opponent of fossil fuels but is also enthusiastic about energy innovation.
In his company Liberty Energy’s Bettering Human Lives report, published last year, which doubles as a kind of manifesto, Wright wrote that “viable paths to reducing greenhouse gas (GHG) emissions can only come from reliable and affordable low-carbon energy technologies,” and specifically listed next-generation nuclear and geothermal, which Liberty had invested in through the geothermal company Fervo and nuclear company Oklo.
“To achieve largescale human betterment, we will need significant future energy additions from nuclear, hydropower, geothermal, and all other viable energy technologies,” the report read.
And he’s often been skeptical of renewables along the lines of many Congressional Republicans, that they aren’t reliable enough and require additional resources to fully support the grid.
“Maybe the biggest problem is intermittency,” Wright said at a Liberty Energy event last year.
“You can build a lot of wind and solar, and then at night, the sun’s not shining and then sometimes the wind doesn’t blow, and you have no energy. So to keep society running, you have to have a whole second separate energy system,” Wright said.
In testimony to the House of Representatives last week, Wright said “If you’re not there at peak demand, you’re just a parasite on the grid, because you just make the other sources turn up and down as you come and go.”
Many critics of the Republican reconciliation bills have noted that much of the electricity generation pipeline is solar, wind, or storage, and so cutting off their tax credits risks leaving the country at an energy shortage while gas turbines take years and years to actually get on the grid.
But as Congress was working on the reconciliation bill, Wright made a series of widely noted public appearances where he promoted clean firm power and continued government support for it.
“My recommendation has been to leave behind the equivalent of the wind and solar tax credits — through if you start construction by 2031 — for nuclear fission and fusion and geothermal,” Wright said at an event earlier this month.
In May, Wright addressed the Nuclear Energy Institute, outlining his support for sunsetting wind and solar tax credits will working to kickstart nuclear power. “My personal goal would be to much more rapidly sunset the technologies that have been around and have been living on decades of subsidies,” Wright said. He also supported a “window” of “favorable treatment” for nuclear and geothermal.
“I’m in favor of every nudge, every incentive we can get from the federal government to restart this industry,” Wright said.
While Wright has been skeptical of wind and solar and optimistic about nuclear and geothermal for years, he’s also started talking more positively about energy storage. In the past, he’s talked up hydrocarbons for “coming with their own storage,” as he put it in a 2018 podcast.
But at an appearance at ARPA-E in March, Wright gave some of his most extended thoughts on energy storage, which sits somewhat awkwardly between variable resources like solar and wind and firm resources like nuclear and geothermal.
“Solar is growing very fast, getting more efficient and taking panels, cheaper materials and developing energy,” Wright said. “The biggest problem there is the sun doesn’t always shine, and we don’t know when clouds are going to come and when it’s not going to shine, but if we can get energy storage better, that’s a game changer.”
At least until 2035.
