Trump Loosens Gas-Car Pollution Rules for 2022-2031

The Trump administration finalized a rule Sept. 28, 2026, easing pollution limits for gasoline cars and pickup-style trucks built for 2022-2031. The Transportation Department calls it 'Freedom Means Affordable Cars.' It undoes Biden-era rules requiring cars to go farther per gallon, slowing yearly gains to a tiny fraction. Fights over pollution, prices, and state enforcement are expected.
