The U.S. Environmental Protection Agency said on Wednesday it is starting efforts to reverse the Biden administration's vehicle emissions rules that would force automakers to build a rising number of electric vehicles.

The EPA's rules put the fleetwide light-duty limit at 170 grams of carbon dioxide per mile for 2027 down to 85 grams in 2032. They don't specify any requirements for a particular type of propulsion system, but automotive executives have said EVs will be needed to comply.

President Donald Trump’s environmental chief moved to revise Biden-era climate mandates curbing greenhouse gas pollution from the nation’s power plants.

The Environmental Protection Agency announced on Wednesday it plans to reconsider a Biden administration regulation that sought to reduce greenhouse gas emissions from power plants, part of the new administration's broader efforts to unwind regulations for the power sector.

President Trump’s Environmental Protection Agency on Wednesday began the process of rescinding vehicle fuel efficiency standards that Republicans deride as a de facto “electric vehicle mandate,” The Post has learned.
