President Donald Trump has announced a proposal to weaken vehicle mileage rules for the auto industry. If the plan announced Wednesday is finalized next year, it would ease pressure on automakers to control pollution from gasoline-powered cars and trucks. The proposal would significantly reduce fuel economy requirements through the 2031 model year. Those requirements set rules on how far new vehicles need to travel on a gallon of gasoline. It's the Trump administration's latest move to reverse Biden-era policies that encouraged cleaner-running cars and trucks, including electric vehicles. Environmentalists said the rule change would increase pollution and raise prices for consumers by allowing less fuel-efficient cars.
