The new rule is a climate win, requiring cars and light-duty trucks to average at least 55 miles per gallon by 2026.

The Environmental Protection Agency tightened fuel mileage rules on new cars and light-duty trucks Monday, reversing a Trump-era policy and signaling how Joe Biden’s administration may end up cutting emissions while its efforts to pass a climate law stall in Congress.

The new rule will require automakers to achieve an average of at least 55 miles per gallon fleetwide by 2026, a sizable increase over the standard of 40.4 mpg set during Donald Trump’s presidency.
