EPA and NHTSA Finalize Fuel Economy and Carbon Dioxide Emissions Standards

The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA) finalized “The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule for Model Years (MYs) 2021-2026 Passenger Cars and Light Trucks.” Per this rule, NHTSA and EPA adopted and modified nationwide standards regulating corporate average fuel economy (CAFE), tailpipe carbon dioxide (CO2) emissions, and use of other air conditioning refrigerants for passenger cars and light trucks for MYs 2021-2026. The final rule established CAFE and CO2 emissions standards that increase in stringency at 1.5% per year from MY 2020 levels over MYs 2021-2026.

For more information, refer to the final rule and EPA's SAFE Vehicles Final Rule website.
