Zero Emission Vehicle (ZEV) Sales Requirements and Low Emission Vehicle (LEV) Standards
Colorado established ZEV standards, pursuant to Colorado’s authority under Section 177 of the Clean Air Act, Title 42 of the U.S. Code, section 7507. All Model Year 2022 and later passenger cars and light- and medium-duty vehicles must meet California motor vehicle emissions and compliance requirements specified in Title 13 of the California Code of Regulations.
In October 2023, Colorado partially 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 in 2027 and require 82% of new passenger vehicles solid in Colorado must be ZEVs by 2032.
