The U.S. Environmental Protection Agency on Wednesday proposed new tailpipe emissions limits that could require as much as 67% of all new vehicles sold in the U.S. by 2032 to be all-electric, representing the country’s most aggressive climate regulations to date. The proposed limits would surpass President Joe Biden’s previous commitment to have EVs make up roughly 50% of cars sold by 2030 and accelerate the country’s clean energy transition.
