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

On August 24, 2018, the Environmental Protection Agency (EPA) and the Department of Transportation's National Highway Traffic Safety Administration (NHTSA) jointly published in the Federal Register a notice of proposed rulemaking entitled, "The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule for Model Years 2021-2026 Passenger Cars and Light Trucks." In the NPRM, the agencies proposed new greenhouse gas (GHG) and Corporate Average Fuel Economy (CAFE) standards for model year 2021 to 2026 light duty vehicles. EPA also proposed to withdraw the waiver it had previously provided to California for that State's GHG and ZEV programs under section 209 of the Clean Air Act, while NHTSA proposed regulatory text that made clear that those State programs would also be preempted under NHTSA's authorities. On September 27, 2019, the agencies published, The Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule Part One: One National Program,” which finalized the two actions related to the waiver and preemption, as: (1) EPA announced its decision to withdraw the waiver; and (2) NHTSA finalized regulatory text related to preemption. The agencies anticipate issuing a final rule on the standards proposed in the NPRM in the near future.
