Program objective

EPA is providing grants to support state governments that are interested in adopting and implementing California’s motor vehicle greenhouse gas and zero emission standards in accordance with Clean Air Act Section 177. The grants are provided under the Inflation Reduction Act (IRA) Section 60105(g) [Public Law 117–169, title VI, Aug. 16, 2022, 136 Stat. 2076]. Under section 177 of the Clean Air Act, states may adopt California’s motor vehicle standards. Section 177 specifies the criteria states must meet when they adopt California’s motor vehicle emission standards, including that the adopted standards to be identical to California’s standards, provide 2 years of lead time, and a waiver must be issued by EPA before a state can enforce such standards.
