The U.S. Environmental Protection Agency (EPA) has announced a new rule to phase down the use of climate super-pollutant hydrofluorocarbons (HFCs). The rule aims to achieve a 40% reduction below historic levels from 2024 through 2028, aligning with the goals of the bipartisan American Innovation and Manufacturing (AIM) Act. This action builds upon the success of the 10% phasedown step implemented for 2022 and 2023. The rule provides regulatory certainty to industry and stakeholders by establishing an allowance methodology for efficient implementation. The EPA views this rulemaking as a crucial step towards their ambitious plans to address climate change and ensure the United States leads in the implementation of the Kigali Amendment.
