The Trump administration has rolled back federal fuel economy standards to 2014 levels, setting a target of just 34.9 mpg by model year 2031 — below even the standards from Trump's first term. The new rule eliminates emissions credits starting in 2028 and removes plug-in vehicles from CAFE fleet calculations, effectively dismantling Biden-era incentives for electric and hybrid vehicles.
Background
Corporate Average Fuel Economy (CAFE) standards are U.S. federal regulations setting minimum fuel efficiency requirements for automakers. The Biden administration had established progressively stricter standards through 2032 to promote electric vehicle adoption.
