Trump administration plans to reverse fuel efficiency regulations implemented by Biden

The United States is preparing to ease its fuel efficiency requirements, marking another reversal of a policy introduced during the Biden administration that aimed to boost electric vehicle adoption. President Donald Trump unveiled the proposal at the White House, emphasizing that the previous standards were unrealistic and increased costs for consumers.

"The way they were handling costs was terrible and it actually made cars worse," Trump stated. Ford CEO Jim Farley, present at the announcement, described the move as a "common sense victory," while environmental organizations criticized it as a setback for public health and the auto industry.

Transportation remains the largest source of greenhouse gas emissions in the U.S., responsible for over 28% of total emissions in 2022, according to the Department of Energy. Under the former policy, automakers were required to achieve an average fuel efficiency of approximately 50 miles per gallon across their fleets by 2031. The current industry average is around 27 miles per gallon. For passenger vehicles, this equated to an annual efficiency increase of roughly 2%.

The National Highway Traffic Safety Administration now proposes less rigorous standards, targeting an average fuel efficiency of about 34.5 miles per gallon by 2031. The administration is also moving to end a program that allowed automakers to purchase credits from companies with higher efficiency, such as Tesla, which had helped manufacturers meet compliance targets and supported the electric vehicle market.

Katherine Garcia, director of Sierra Clubs Clean Transportation for All initiative, warned that the rollback would increase emissions and raise fuel costs for families. "This step would set the auto industry back, keep polluting vehicles on the roads, and threaten the health of millions, especially children and the elderly," she said.

Ford's Farley argued that the revised rules better reflect consumer demand and represent a positive adjustment for multiple reasons.

The Biden administration had promoted its fuel efficiency plan as a measure to reduce reliance on foreign oil, lower fuel expenses, and cut pollution, with an estimated prevention of over 700 million metric tons of CO₂ emissions by 2050. While automakers could use any technology to meet the standard, the targets were heavily reliant on increased electric vehicle sales. This reliance generated pushback from some manufacturers who had begun scaling back EV investments due to uncertain demand.

The major U.S. automakersStellantis, General Motors, and Fordown some of the least fuel-efficient fleets, particularly with trucks and SUVs. GM had expressed concerns that insufficient EV sales could force the closure of plants producing less efficient vehicles to comply with the previous rules, according to CEO Mary Barra.

The new proposal is still undergoing formal rule-making. Trump suggested it could reduce vehicle prices by around $1,000, compared with Biden's estimated $600 in lifetime fuel savings for car owners. Kathy Harris from the Natural Resources Defense Council criticized the plan, saying it primarily benefits the oil industry and undermines driver savings.
