US declares Biden fuel efficiency rules exceed legal authority

The Transportation Department has paved the road for looser fuel economy standards in the United States by declaring on Friday that former President Joe Biden’s administration overstepped its authority when it assumed a high uptake of electrical vehicles to calculate rules.

The Department made this declaration when it published its final "Resetting of the Corporate Average Fuel Efficiency Program" (CAFE). Fuel economy requirements will be revised by a separate rule issued by the Trump administration.

"We make vehicles more affordable in the United States and we are making it easier to manufacture them." In a statement, Transportation Secretary Sean Duffy said that the previous administration used CAFE standards to mandate electric vehicles.

In writing the rule under Biden last year, the National Highway Traffic Safety Administration of the Department of Transportation (NHTSA) "assumed that significant numbers of EVs will continue to be manufactured regardless of the standards established by the agency," the department said on Friday.

Duffy signed in January an order that directed NHTSA to cancel fuel economy standards set under Biden, for model years 2022-2031. These standards were intended to reduce the fuel consumption of cars and trucks.

Senate Republicans have proposed to eliminate fines for failing to meet CAFE standards as part of an extensive tax bill. This is the latest step to make it easier for automakers build gas-powered cars.

In 2018, Chrysler's parent company Stellantis, which is owned by Chrysler, paid nearly $400 million in penalties between 2016 and 2019. GM paid $128.2 millions in penalties between 2016 and 2017.

Stellantis stated that it backed the Senate Republican proposal, "to provide relief until DOT develops their proposal to reset CAFE standards." The current standards are not in line with the market realities and immediate relief is needed to preserve affordability and freedom.

GM has declined to comment.

NHTSA, under Biden in June 2024, said that it would increase CAFE requirements for light-duty vehicle to approximately 50.4 miles per liter (4.67 litres per 100 km), from 39.1 mpg at present.

Last year, the agency estimated that the rule for cars and trucks could reduce gasoline consumption and emissions by 659 millions metric tons. This would result in a reduction of fuel costs and a net benefit of $35.2 billion. (Reporting and editing by Aidan Lewis, Peter Graff, and David Shepardson)
