Trump administration cuts 2031 fuel-economy target, sparking California concerns

The White House in Washington announced on September 29 that the 2031 corporate-average fuel-economy target had been lowered to 34. 9 miles per gallon, a reduction that California officials said jeopardizes the state’s climate-change goals. President Donald Trump had earlier announced on September 26 that his administration was rolling back the Biden-era fuel-economy rules, replacing the electric-vehicle mandate with less demanding standards.

The White House later finalized the rules, cutting the required annual efficiency gain for automakers from 2 % to 1 % and saying the change would lower vehicle prices. Officials also noted that the revised standards could raise fuel consumption.
