Justice Department Challenges California's Emissions Standards

The U.S. Department of Justice has filed two complaints against the California Air Resources Board (CARB) regarding the state's enforcement of preempted emissions standards through its "Clean Truck Partnership" with heavy-duty truck and engine manufacturers. This move supports President Donald J. Trump's commitment to end the electric vehicle mandate, level the regulatory playing field, and promote consumer choice in motor vehicles. The Justice Department's actions follow the Congressional Review Act invalidating EPA's preemption waivers for CARB's heavy-duty truck regulations in June 2025. CARB's regulations aim to implement an EV mandate in California and other states adopting California's rules.
