On August 2, 2018, EPA and NHTSA released a proposed rule that would roll back the current U.S. climate pollution and Corporate Average Fuel Economy (CAFE) standards. The current standards require gradual climate pollution reductions every year, which will spur increases in fuel efficiency for all new vehicles sold between now and 2025. The proposal recommends capping U.S. climate pollution and fuel economy targets at model year (MY) 2020 levels – with no further increases in later years.
This analysis indicates that rolling back the current U.S. climate pollution and fuel economy standards in this way will cost the average American family as much as $514 per year during the timeframe that they own MY 2025 vehicles.
M.J. Bradley & Associates also conducted an analysis of the state-by-state impacts of EPA's proposal, available here.
