On January 1, 2022, the U.S. officially started its phase down of HFC refrigerants, such as R-410A and R-404A. Beginning this year, the production of HFC refrigerants will be reduced by 10%, while a steeper cut comes in 2024, when production must be reduced to 60% of the baseline established by the Environmental Protection Agency (EPA).
These production cuts are a result of the American Innovation in Manufacturing (AIM) Act, which became law in December 2020. Under this legislation, Congress gave the EPA the authority to phase down the consumption and production of high-GWP HFC refrigerants in the U.S. by 85% over the next 15 years.
