Question

Quizplus · Accepted Answer

HFCs (hydrofluorocarbons) and HCFCs (hydrochlorofluorocarbons) are replacements for CFCs (chlorofluorocarbons), which were found to deplete the ozone layer. HFCs and HCFCs have lower ozone-depleting potential, but they are still potent greenhouse gases with high global warming potentials. They are commonly used in refrigeration, air conditioning, and foam insulation.
