DC Circuit Stays Litigation over EPA Rescission of California Waiver to Regulate Vehicle Emissions

On February 8, 2021, the D.C. Circuit issued an order granting the Biden administration’s motion to stay litigation over Part 1 of the Trump-era Safer Affordable Fuel Efficient Vehicles (SAFE) Rule. The order was issued in Union of Concerned Scientists v. NHTSA (No. 19-1230) and consolidated cases. As detailed in our earlier alerts, Part 1 of the SAFE Rule rescinded the waiver EPA granted California to regulate vehicle greenhouse gas emissions and to implement a zero-emission vehicle program. Part 2 of the SAFE Rule finalized new standards for corporate average fuel economy (CAFE) and carbon dioxide emissions for passenger vehicles and light-duty trucks sold from model years 2021 through 2026.
