As we reconsider nearly $1 trillion of regulatory costs, we will abide by the rule of law to protect consumer choice and the environment,” said EPA Administrator Lee Zeldin in a news release Wednesday.

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.

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