California Is Quietly Trump-Proofing Its EV Rules

Meanwhile, automakers and policymakers alike are looking to it for inspiration.

Even as the Environmental Protection Agency was preparing to release federal tailpipe emissions rules that will steer more U.S. drivers into electric vehicles, California was working in the background to harden its own, more stringent emissions standards.

On Tuesday, the state announced an agreement with Stellantis, the automaking conglomerate that contains the Chrysler, Jeep, Dodge, and Ram brands to comply with more restrictive tailpipe emissions rules through 2026. California also said Stellantis would go along with its electrification mandates through 2030 — regardless of whether either is struck down by federal regulators or the courts.

The agreement is part of California’s effort to preserve its ability to set emissions standards and mandate electrification even with a hostile White House and judicial branch. By trying to get enough of the industry to agree to its rules voluntarily and not join any effort that may arise to throw them out, it hopes either to preserve its rule-making ability or, in the worst case scenario, leverage the industry’s desire for predictability to keep the rules themselves intact.

David Clegern, public information officer at the California Air Resources Board, told me there was no connection between Tuesday’s agreement and today’s EPA announcement. The deal “gives Stellantis flexibility in how they meet California's existing greenhouse gas emissions vehicle requirements," he said. In exchange, the state gets an even deeper emissions cut than it would otherwise — some 10 million extra tons of foregone greenhouse gas emissions.

Stellantis also agreed “not to oppose California’s authority under the Clean Air Act for its greenhouse gas emissions and zero-emissions vehicle standards,” the California Air Resources Board said in its announcement of the agreement.

California has long had the ability to set its own emissions standards thanks to the structure of the Clean Air Act and a waiver from the EPA. California got some automakers to agree to a version of Obama-era tailpipe emissions rules in the summer of 2019 that the Trump administration had planned on scrapping, after which Trump officials revoked California’s ability to set emissions rules. California finalized its agreement with the automakers the following year, then regained its authority to set emissions rules in 2022.

The principle behind the Stellantis deal is similar to those earlier agreements, Clegern said. Stellantis had been on the outside looking in on California’s deals with automakers, and late last year initiated an administrative process to try to get them thrown out. (It was unsuccessful.) Now, the company has agreed not only to implement emissions and electrification rules, but also to invest in electrification in the state by spending $4 million on charging infrastructure in California and $6 million in states that also adopt California’s emissions rules.

Meanwhile, the EPA is working on a new waiver process for California’s electrification standards, which would need to be completed before the end of this year to both avoid interference from a potential incoming Republican administration and to make sure it applies on the schedule the state has set out, Kathy Harris, clean vehicles director at the Natural Resources Defense Council, told me. The rules, known as the Advanced Clean Car Standard II regulations, start with the 2026 model year and apply through 2035 and mandate that all new car sales in the state be electric by the middle of the 2030s.

About a dozen other states so far have adopted the ACC II standards, including Massachusetts, New York, and Oregon.

Many commenters on the EPA car emission proposal set out the California rules as a model for what the agency should do. “Vehicle manufacturers also commented that they had extensive collaboration with the California Air Resources Board (CARB) during the development of CARB’s recently finalized Advanced Clean Car II (ACC II) standards,” according to the final rule, “and industry broadly recommended that EPA adopt the ACC II program in lieu of our proposed standards.”

In the end, the EPA rules follow a different model than the California standards, Harris said. Crucially, the EPA isn’t mandating electrification. In remarks at a White House even on Wednesday, EPA administrator Michael Regan emphasized that they were instead technology neutral and performance based, meaning that they leave it up to the automakers to figure out how to comply.

David Reichmuth, the senior engineer in the Union of Concerned Scientists’ clean transportation program, told me that, compared to California's, the EPA rules “are distinct in what they regulate and how they regulate vehicles,” he told me. Nevertheless, “they are pulling in the same direction in trying to reduce emissions from transportation and air pollution from vehicles.”

California’s ability to set its own emissions rules is not just likely to be questioned by a Republican administration should Donald Trump win in 2025, it also could be at risk in the courts. Ohio and other states with Republican attorneys general sued the EPA in 2022 over the existence of the California waiver in a case that was heard by the D.C. Circuit Court of Appeals last fall. The ruling is still pending.

Are Pollsters Getting Climate Change Wrong?

Why climate might be a more powerful election issue than it seems.

Climate change either is or isn’t the biggest issue of our time. It all depends on who you ask — and, especially, how.

In March, as it has since 1939, Gallup asked Americans what they thought was the most important problem facing the country. Just 2% of respondents said “environment/pollution/climate change” — fewer than those who said “poor leadership” or “unifying the country” (although more than those who said “the media.”) Pew, meanwhile, asked Americans in January what the top priority for the president and Congress ought to be for this year, and “dealing with climate change” ranked third-to-last out of 20 issues — well behind “defending against terrorism,” “reducing availability of illegal drugs,” and “improving the way the political system works.”

AM Briefing: Earth Day Edition

On expanding solar access, the American Climate Corps, and union news

Biden’s Big Earth Day Agenda

Current conditions: Torrential rains forced Mauritius to shut down its stock exchange • “Once in a century” flooding hit southern China • In the Northern Hemisphere, the Lyrid meteor shower peaks tonight.


1. Biden kicks off Earth Day with $7 billion for expanding solar access

Today is Earth Day, but President Biden and his cabinet are celebrating all week long. Senior members of the administration have scheduled a national tour of events and announcements related to the president’s climate and environmental record. It starts with Biden’s visit to Prince William Forest Park in Triangle, Virginia, today, where he will announce $7 billion is being awarded to 60 state and local governments, tribes, and national and regional nonprofits through the Environmental Protection Agency’s Solar for All initiative, which aims to support solar in low- to moderate-income communities. The average grant size will be more than $80 million, and the funding will be used to design new programs and bolster existing ones that subsidize the cost of rooftop solar installations, community solar projects, and battery storage.

Biden’s $7 Billion Solar Bonanza

The Solar For All program is the final piece of the $27 billion Greenhouse Gas Reduction Fund.

The great promise of solar panels — in addition to their being carbon-free — is the democratization of energy. Anyone can produce their own power, typically for less than the going utility rate. The problem is that those who stand to benefit the most from this opportunity haven’t been able to access it.

That pattern could change, however, with Solar for All, a $7 billion program under the Environmental Protection Agency to support solar in low- to moderate-income communities. On Monday, the Biden administration announced it was awarding the funds to 60 state and local governments, tribes, and national and regional nonprofits, at an average grant size of more than $80 million.
