December 4, 2025 Trump Admin to Slash Fuel Efficiency Standards Enacted Under the Biden Admin ---------------------------------------------------------------------------- The Trump administration is seeking to slash fuel efficiency standards enacted under the Biden administration. Under current rules, U.S. automakers are required to boost the fuel efficiency of passenger cars and light trucks to about 50 miles per gallon by 2031. The revised standards proposed by the National Highway Traffic Safety Administration would cut that to just 34 miles per gallon. In a statement, the Center for Biological Diversity wrote, "In one stroke, Trump is worsening three of our nation's most vexing problems: the thirst for oil, high gas pump costs, and global warming." .
