Title: +The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule for Model Years 2021-2026 Passenger Cars and Light Trucks 

The Department of Transportation's National Highway Traffic Safety Administration (NHTSA) and the U.S. Environmental Protection Agency (EPA) proposed a rule to adjust the corporate average fuel economy (CAFE) and greenhouse gas (GHG) emissions standards for model years (MYs) 2021 through 2026 light-duty vehicles. EPA established national GHG emissions standards under the Clean Air Act that extend through 2025, and NHTSA established augural CAFE standards for MY 2022-2025 vehicles under the Energy Policy and Conservation Act, as amended by the Energy Independence and Security Act (EISA). This joint rulemaking proposes adjustments to those standards, following conclusion of the Mid-Term Evaluation (MTE) process and EPA's Final Determination that it is appropriate to adjust the MY 2022-2025 GHG emission standards.
