New federal vehicle emissions standards announced Wednesday introduce the strictest limits ever in place in the U.S.

The standards introduced by the Environmental Protection Agency are part of the Biden administration’s push to increase electric-vehicle manufacturing and adoption in an effort to curb emissions’ impact on air quality.

The new restrictions apply to 2027 to 2032 models, and the EPA will let automakers choose how they comply, whether through electrification or other technologies.

The Biden administration earlier targeted half of new-vehicle sales to be electric by 2030, but the new standards reach beyond that goal to aim for 67% of light-duty vehicles and 46% of medium-duty vehicle sales by the 2032 model year.

For gas-powered models, the EPA said it expects the new standards to spur widespread use of filters and carbon dioxide-cutting technology.

Many carmakers have already set goals of robust EV sales by the end of the decade and are already starting to gain some ground on market leader Tesla.
