Stringent tailpipe emissions and mileage rules were part of the Biden administration's pledge to clean up the nation’s vehicles and reduce use of fossil fuels by incentivizing growth in EVs. EVs do not use gasoline or emit greenhouse gases.

The Trump administration said on Tuesday it will rescind the long-standing finding that greenhouse gas emissions endanger human health, removing the legal foundation for all U.S. greenhouse gas regulations.

Known as the “endangerment finding,” the 2009 declaration has served as the basis for federal rules limiting greenhouse gas pollution from power plants, cars and trucks, and the oil and gas industry.
