This law revokes a federal Environmental Protection Agency waiver that had authorized California to enforce its Advanced Clean Cars II (ACC II) regulation. The ACC II regulation required that, beginning in model year 2026, zero-emission vehicles must constitute an increasing percentage of each automaker's new vehicle sales in California, escalating to a point where new gas-powered vehicles would be effectively prohibited by 2035. The waiver also allowed other states to adopt California's standards, and many did, including Colorado, Maryland, Massachusetts, New Jersey, New York, Pennsylvania, and Washington.
Under the Congressional Review Act, this law nullifies the EPA's January 6, 2025 decision to grant California's waiver request. The law prevents the EPA from approving any future waivers that are substantially the same as the one disapproved here. This means California and the 12 other states that had adopted the ACC II regulations can no longer enforce these emission standards for passenger vehicles.
The practical effect of this law is that automakers are no longer required to meet California's zero-emission vehicle targets in those states. Consumers in California and other affected states retain the ability to purchase electric vehicles if they choose, but manufacturers are no longer mandated to achieve specific percentages of zero-emission sales. The law does not affect California's earlier Advanced Clean Cars I regulations or other existing Clean Air Act waivers that California had previously received.
This law was signed by the President on June 12, 2025, and takes effect immediately. It represents a significant shift in federal oversight of state emission standards and reflects a different approach to vehicle emission regulation compared to the previous administration's policy.
