Summary
Hydrofluorocarbons (HFCs) are greenhouse gases (GHGs) commonly used by federal agencies in a wide variety of applications, including refrigeration, air-conditioning (AC), building insulation, fire extinguishing systems, and aerosols. HFCs have high global warming potential (GWP), raising concern about their impacts as they become increasingly used as replacements for ozone-depleting substances (ODS), and as economic growth spurs demand for new equipment, especially in the refrigeration/AC sector. Information about ongoing domestic efforts and tools to address HFCs, sector, is provided below. To help agencies monitor progress, the amendment also requires contractors to keep track of and report on the amounts of HFCs added or removed during routine maintenance, service, repair, and disposal of all government equipment, appliances, and supplies.
Key words: Hydrofluorocarbons (HFCs), greenhouse gases (GHGs), global warming potential (GWP), Developing countries
