Protecting Our Climate by Reducing Use of HFCs
Hydrofluorocarbons (HFCs) are potent greenhouse gases (GHGs). The American Innovation and Manufacturing (AIM) Act authorizes EPA to address HFCs by: phasing down their production and consumption, maximizing reclamation and minimizing releases from equipment, and facilitating the transition to next-generation technologies through sector-based restrictions on HFCs. This website provides information on HFCs and the AIM Act.
