The memo singles out Biden's finalized Corporate Average Fuel Economy (CAFE) standards, which regulate how far vehicles must travel on a single gallon of fuel. U.S. Department of Transportation (DOT) officials estimated the new standards would have pushed the average fuel efficiency of new cars and sport utility vehicles over 50 miles per gallon by 2031. The Biden administration subsequently weakened the rules.
"The memorandum signed today specifically reduces the burdensome and overly restrictive fuel standards that have needlessly driven up the cost of a car in order to push a radical Green New Deal agenda," Duffy said in a
statement. "The American people should not be forced to sacrifice choice and affordability when purchasing a new car."
However, according to a 2024 NHTSA
analysis, Biden's CAFE standards would have saved consumers nearly $23 billion in fuel costs and avoided the burning of approximately 70 billion gallons of gasoline through 2050.
Critics of the Trump administration's fossil fuel agenda also underscored the importance of CAFE standards in reducing gasoline and diesel consumption and combating planetary heating, which is driven primarily by burning fossil fuels. Some also noted that Duffy
questions whether human activity is causing climate change.
"These commonsense, popular fuel economy standards save drivers money at the pump and reduce dangerous pollution from vehicles," Karen García, director of the Sierra Club's Clean Transportation for All campaign, said in a statement Wednesday. "Drivers spend excessive amounts of money to fuel their cars, and it's often a large part of household expenses."
"Sean Duffy is selling American families out to Big Oil, burdening us with higher fuel prices and more polluting gas-guzzlers that harm our health," García added.
Duffy's announcement is part of a wider Trump administration push to roll back Biden's efforts to boost electric vehicles. The U.S. Environmental Protection Agency is also taking aim at California's plan to ban the sale of gasoline-only new vehicles by 2035.
"As sad as it is, it's no surprise that climate denier Sean Duffy's first act at DOT is to advance Trump's harmful deregulatory agenda and roll back fuel economy standards," Will Anderson, electric vehicle policy advocate with Public Citizen's Climate Program,
said Wednesday.
"Such a rollback would not only hinder consumer choices for more fuel-efficient vehicles while putting the U.S. auto industry further behind global competitors, it would raise consumer's costs when fueling—all to boost oil and gas industry profits," Anderson added.
