The administration of U.S. President Joe Biden on Thursday proposed new mileage standards and limits on greenhouse gas emissions from cars and trucks that exceeded what some environmentalists feared would be issued.
The fuel economy and emissions requirements proposed by the Environmental Protection Agency and Department of Transportation would strengthen mandates eased by the Trump administration — and, over time, mark a return to a more stringent path charted by former President Barack Obama in 2012.
"Today, I am following through with a campaign commitment to reverse the previous administration’s short-sighted rollback of vehicle emissions and efficiency standards,” Biden said at a White House event to announce the new standards as well as a national goal for half of the new cars sold in the U.S. be powered by batteries or other no-emission technology.
