Compounds containing hydrogen, fluorine, and carbon atoms, introduced as alternatives to ozone-depleting substances in serving many industrial, commercial, and personal needs.

HFCs are emitted as by-products of industrial processes and are also used in manufacturing. They do not significantly deplete the stratospheric ozone layer, but they are powerful greenhouse gases with global warming potentials ranging from 140 (HFC-152a) to 11,700 (HFC-23).
