Zero Emission Vehicle (ZEV) Sales Requirements and Low Emission Vehicle (LEV) Standards

Washington adopted the California motor vehicle emissions and compliance requirements specified in Title 13 of the California Code of Regulations. The Washington Department of Ecology adopted rules to implement these emissions standards for passenger cars, light-duty trucks, and medium-duty passenger vehicles, known as the Clean Car Law.

In December 2022, Washington adopted the California vehicle emissions standards and compliance requirements set forth in the California Air Resources Board Advanced Clean Cars II regulation. These new emissions standards and requirements will begin with model year 2026 and require that 100% of new passenger vehicles sold in Washington must be ZEVs by 2035.
