What happened

President Donald Trump announces plans to weaken fuel efficiency and emissions rules for cars and trucks in the Oval Office at the White House in Washington, DC, on December 3rd, 2025. It's a nail in the coffin for Biden-era standards that would have required fleet average fuel economy to reach 50.4 miles per gallon by model year 2031. President Donald Trump's plan requires 34.9 miles per gallon, not much higher than the 30.1-mile-per-gallon target previously set for model year 2024.
