The fuel-efficiency standards for new cars and light trucks are expected to be rolled back by the incoming Trump administration.

Sources indicate that President-elect Trump"s advisers plan to reassess the fuel economy requirements established in June, with the aim of dismantling policies set by the Biden administration.

In addition, the Trump team is targeting regulations from the US Environmental Protection Agency that restrict tailpipe emissions of carbon dioxide and other pollutants.

This shift in the federal approach to automotive emissions and fuel efficiency reflects the administration"s broader agenda to reverse existing environmental policies.
