Program objective

These grants are provided under Section 60114 of the Inflation Reduction Act, Climate Pollution Reduction Grants, 42 U.S. Code § 7437 (or Public Law 117–169, title VI, Aug. 16, 2022, 136 Stat. 2076), which amended the Clean Air Act (CAA) by creating Section 137 for Greenhouse Gas Air Pollution Plans and Implementation Grants. Section 137 of CAA authorizes the EPA to fund planning grants to reduce carbon dioxide, hydrofluorocarbons, methane, nitrous oxide, perfluorocarbons, and sulfur hexafluoride; and grants to states, air pollution control agencies, municipalities, Tribes, or a group of two or more of these entities to implement activities from those plans. Specifically, the CPRG grant program provided funding of $250 million for planning grants to eligible entities and approximately $4.6 billion to implement projects from those plans. Once completed, these plans will establish reduction targets and lay out a roadmap for expeditious implementation of investment-ready policies, programs, and projects to reduce emissions.
