Protecting Our Climate by Reducing Use of HFCs
Hydrofluorocarbons (HFCs) are potent greenhouse gases (GHGs) intentionally developed as replacements for ozone-depleting substances (ODS) in the refrigeration, air conditioning, aerosols, fire suppression, and foam blowing sectors. They have global warming potentials (GWPs) (a measure of the relative climate impact of a GHG) that can be hundreds to thousands of times greater than carbon dioxide (CO2). HFC use is growing worldwide due to the phaseout of ODS and increasing use of refrigeration and air-conditioning equipment globally.
The American Innovation and Manufacturing (AIM) Act was enacted by Congress on December 27, 2020. The AIM Act directs EPA to address the environmental impact of hydrofluorocarbons (HFCs) by: phasing down production and consumption, maximizing reclamation and minimizing releases from equipment, and facilitating the transition to next-generation technologies through sector-based restrictions. This website provides information on HFCs, the AIM Act, and regulations promulgated under the AIM Act.
