AG Rob Bonta filed an amicus brief in the Sixth Circuit Court of Appeals in support of the National Highway Traffic Safety Association (NHTSA)’s fuel-economy standards for passenger cars, light trucks, and heavy-duty trucks. The NHTSA standards are designed to enhance fuel efficiency for vehicles and benefit consumers across the country. Currently, Republican-led states and oil industry groups are not only challenging these federal fuel-economy standards but also using their lawsuit to attack California’s unrelated zero-emission vehicle (ZEV) standards. The amicus brief explains why that attack on state-law emission standards—designed to reduce smog-forming and planet-warming air pollution—has no place in a challenge to federal-law fuel efficiency standards.
