- The Biden administration on Wednesday approved California’s ban on gas cars by 2035.
- Trump has promised to revoke California’s authority to set strict limits on tailpipe pollution.
- It’s a high-stakes fight over the future of electric vehicles and tackling the climate crisis.
The stage is set for another battle between President-elect Donald Trump and California over the state’s aggressive push into electric vehicles that could affect the rest of the country.
The Environmental Protection Agency on Wednesday said California can go ahead with its ban on the sale of new gas-powered cars by 2035. The approval is an attempt to safeguard the state’s strict limits on tailpipe pollution from Trump’s promise to revoke them and roll back other federal incentives for electric vehicles.
The stakes are high for automakers because what happens in California can dictate companies’ broader EV strategies and the pace of the country’s shift away from fossil fuels. The state accounts for some 11% of the US auto market and is also the top EV market in the country. In the first half of 2024, EVs and hybrids accounted for nearly 40% of sales in California.
On top of that, 11 other states and Washington D.C. have adopted rules similar to California’s as they seek to reduce the country’s largest source of greenhouse gas emissions. The rules require automakers to sell a growing number of zero-emissions vehicles over time. In 2026, at least 35% of new cars, pickup trucks, and SUVs must be electric in California and five other states, while other states’ targets kick in in 2027.
Automakers largely support easing emissions regulations
While Trump will face legal challenges in trying to roll back California’s rules, he could find some automakers on his side.
The Alliance for Automotive Innovation, a lobbying group representing most new vehicle manufacturers in the US, has already asked Trump to ease emissions regulations but keep federal tax incentives that keep EVs affordable.
John Bozzella, president of the alliance, said Wednesday that the waiver was an expected development and the Trump administration will likely revoke it next year.
“We’ve said the country should have a single, national standard to reduce carbon in transportation,” Bozzella said in a statement. “But the question about the general authority of California to establish a vehicle emissions program – and for other states to follow that program – is ultimately something for policymakers and the courts to sort out.”
Trump, some Republican lawmakers, and groups linked to fossil fuel interests have repeatedly attacked EVs on the campaign trail, falsely claiming that Americans would be forced to abandon their gas-powered vehicles.
Those attacks come as the EV market deals with a marked slowdown in demand, forcing many companies to reasses their long-term plans for battery-powered cars and, in some cases, add more hybrids to the mix. A pullback in production has made it harder for many companies to meet long-term emissions requirements. Automakers including General Motors, Ford, and Stellantis have laid off thousands of workers.
Auto market analysts, environmental lawyers, and policy experts told Business Insider that they expect the shift to zero-emissions vehicles to continue regardless of who’s in the White House — albeit at a slower pace if Trump and Congress overturn tax incentives to buy EVs and investments in charging infrastructure.
“Whatever the Trump administration does this time, automakers’ concerns about stability will come up again because all of these manufacturers have said zero-emissions vehicles are the future,” Sean Donahue, an attorney who’s represented the Environmental Defense Fund in litigation over California’s emissions waiver, said.
He added that there’s pressure from regulators in other countries to address the climate crisis. US automakers also don’t want to fall far behind competitors in countries like China, where affordable EVs have taken off.
California looks to ‘Trump-proof’ its regulations
Even if Trump does revoke California’s emissions waiver, Gov. Gavin Newsom is already trying to “Trump-proof” the state, including its EV and climate policies.
Newsom said he would restore rebates for consumers who buy EVs if Trump ends the federal $7,500 tax credits enacted in the Inflation Reduction Act. This month, the state’s energy commission approved a $1.4 billion investment in EV charging and hydrogen fuel stations over the next four years. The commission said the funding could help build nearly 17,000 new public chargers for passenger vehicles — on top of the 152,000 available now.
Newsom also convened a special legislative session to bolster California’s defenses against Trump’s attacks. Lawmakers could pass $25 million in new funding for the California Department of Justice so the state can file litigation against the Trump administration. That will likely happen if Trump revokes the state’s tailpipe pollution waiver.
Karoline Leavitt, a spokeswoman for the Trump transition team, said that Trump plans to stop what he says are attacks on gas-powered cars.
“When he takes office, President Trump will support the auto industry, allowing space for both gas-powered cars AND electric vehicles,” she said in an email.
Ann Carlson, a professor of environmental law at the University of California at Los Angeles, told Business Insider that she expects the Trump administration to face an uphill legal battle.
She said the EPA has approved California’s authority to set strict rules for tailpipe pollution for decades because the state’s air quality is so bad. Otherwise, areas including Los Angeles and the Central Valley wouldn’t comply with federal air pollution laws and could be penalized.
“The sanction is the withholding of federal highway funds,” Carlson — who recently served as chief counsel to the National Highway Traffic Safety Administration — said. “It’s quite draconian. So California has a pretty good argument that it needs these waivers to meet federal law.”
The Supreme Court last week agreed to consider a lawsuit that oil and gas producers filed against the EPA over its waivers allowing California to set stricter limits on tailpipe pollution than the federal government. However, SCOTUS will only decide whether fossil fuel makers have standing to sue over what they say is bureaucratic overreach and won’t consider whether California’s waiver is legal.
James Di Filippo, a principal policy analyst at the research firm Atlas Public Policy, said automakers will likely continue to walk back their EV investments while the legal battles play out. Companies could seek another compromise with California to restore more certainty as they plan new vehicle models for years to come.
“If they’re uncertain about a regulatory outcome, they’ll default to a less intense push,” he said.
