Hydrofluorocarbons (HFCs), Chapter 2 in Scientific Assessment of Ozone Depletion: 2018.

Author(s) : MONTZKA S. A., VELDERS G. J. M.

Type of excerpt: Book chapter

Summary

Hydrofluorocarbons (HFCs) were used as ODS alternatives because they do not contain ozone-depleting chlorine or bromine; in addition, most HFCs have smaller climate impacts per molecule than the most widely used ODSs they replaced. Long-lived HFCs, CFCs, and HCFCs, however, are all potent greenhouse gases, and concerns were raised that uncontrolled future use of HFCs would lead to substantial climate warming. As a result of these concerns, HFCs were included as one group of greenhouse gases for which emissions controls were adopted by the 1997 Kyoto Protocol under the 1992 United Nations Framework Convention on Climate Change (UNFCCC).
Although the radiative forcing supplied by HFCs is currently small, the Kigali Amendment was designed to ensure that the radiative forcing from HFCs will not grow uncontrollably in the future. HFC concentrations are currently monitored through atmospheric measurements.
