  2. Reducing HFCs

Sector Fact Sheets

Hydrofluorocarbons (HFCs) are used in applications such as air conditioning, refrigeration, fire suppression, solvents, foam blowing agents, and aerosols. HFCs are greenhouse gases with global warming potentials (GWPs) that can be hundreds to thousands of times more potent than carbon dioxide (CO2). Their use has been rapidly increasing worldwide due to the global phaseout of ozone-depleting substances (ODS) and increased demand for refrigeration and air conditioning.  In many cases, alternatives are available or under development that either non-fluorinated or are HFC and HFC blends with lower GWPs than the HFC or HFC blends they replace. These documents provide information on uses of HFCs and low-GWP alternatives to high-GWP HFCs.
