Trump administration to slash clean car rules aimed at cutting climate emissions

The Trump administration on Monday announced it was slashing clean car rules that had been aimed at reducing planet-heating emissions and boosting electric vehicles.

The move, which was criticized by environmentalists, relaxes requirements on automakers to control pollution from gasoline-powered cars and light trucks for model years 2022 through 2031.

The new rule, announced by the Department of Transportation, reverses a push by the Biden administration to accelerate the transition to EVs. Transportation is the largest source of climate emissions in the United States, accounting for about 28% of total US greenhouse gas emissions according to the US Environmental Protection Agency (EPA).

Monday’s move follows the Trump administration’s rollback of the government’s ability to impose requirements to track, report and limit climate-heating pollution from cars and trucks.

Donald Trump said on Truth Social Saturday that the less stringent mileage requirements would “take the waste out of building cars in America” and save families “thousands on a new, beautiful and safe car”, while boosting auto production in the US.

Trump has repeatedly pledged to end what he falsely calls an EV “mandate”, referring incorrectly to Joe Biden’s target that half of all new vehicle sales be electric by 2030. No federal policy has mandated auto companies to sell EVs.

Sean Duffy, the US transportation secretary, hailed the new initiative – called Freedom Means Affordable Cars – which the agency said would reduce the average cost of new vehicles by $1,300, and save consumers $138bn over the next five years.

Duffy said: “Thanks to President Trump’s leadership, we have finally ended the illegal mandate that forced automakers to produce more expensive electric vehicles that American families didn’t want.”

Green groups condemned the new rules. Dan Becker, director of the Center for Biological Diversity’s safe climate transport campaign, said that the final rule “ignores the feasibility of clean technology and the millions of fuel-efficient cars already on the road”.

“Trump is tanking sensible mile per gallon standards at the worst possible time for consumers, who are getting hit with sky-high prices at the pump,” Becker said in a statement. “Consumers will pay the price for these reckless rollbacks while Trump’s Big Oil and Big Auto buddies reap the short-term profits.”

Katherine García, director of the Sierra Club’s Clean transportation for all campaign, vowed the environmental group would fight the rule and said that the loosening of fuel standards would “make driving more expensive too”.

Fuel economy requirements set out how far new vehicles need to travel on a gallon of gasoline. The Biden administration had increased required fuel efficiency for cars by ​8% annually for model years 2024 and 2025, 10% for 2026 and 2% annually from 2027 to 2031.

The Trump ‌administration ⁠in December proposed retroactively revising down the 2022 model year fuel economy standard and then raising it between 0.25% and 0.5% annually through 2031. It estimated its ​proposal would cut average ⁠new vehicle costs by $930 each.

But it would increase fuel consumption by about 100bn gallons through 2050, fuel spending by $185bn and carbon dioxide emissions ​by about 5%, the department said.
