EPA Proposes Rule Banning R410A and Other Refrigerants in 2025

On December 9, 2022, the U.S. Environmental Protection Agency (EPA) proposed a rule under the American Innovation and Manufacturing (AIM) Act that authorizes the EPA to limit or prohibit use of hydrofluorocarbons (HFCs) in line with the Kigali Amendment. The proposed rule applies to HFC refrigerants used in refrigeration, air conditioning, and heat pumps as well as in certain foams and aerosol products. The HFC phasedown pursued by the U.S. government targets a 40% reduction in 2024 and an 85% reduction in 2036.
