WASHINGTON (AP) — A coalition of automakers has told the Biden administration it would agree to raise mileage standards to reduce tailpipe emissions but with tradeoffs and at rates lower than those brokered by California with five other car manufacturers.

If agreed to, the proposal could give President Joe Biden a quick win by securing cuts in greenhouse gas emissions rather than waiting months, if not years, to legally undo a giant rollback approved when Donald Trump was president.

But environmental groups say the proposal doesn’t go far enough to ward off the damaging effects of climate change and automakers are rejecting tougher Obama-era standards that they have the technology to meet.

It also could result in two different sets of standards, one for California and the states that follow its rules, and another for the rest of the country. This could drive up vehicle prices.

Asked Friday about the proposal, the White House said discussions with the auto industry on a fuel emissions standard were still early.
