Hydrofluorocarbons (HFCs)

Definition

CFC substitutes containing hydrogen, fluorine, and carbon but no chlorine; they have essentially zero ozone-depletion potential, although some are powerful greenhouse gases

CFC substitutes containing hydrogen, fluorine, and carbon but no chlorine; they have essentially zero ozone-depletion potential, although some are powerful greenhouse gases

STB-4.BSTB-4.B.1
Hydrochlorofluorocarbons (HCFCs)
Not Started

Transitional CFC substitutes that contain chlorine but break down more readily in the lower atmosphere, giving them lower but nonzero ozone-depletion potential

STB-4.B
Ozone-Depletion Potential (ODP)
Not Started

A measure of a substance’s ability to destroy stratospheric ozone relative to a reference substance; an ODP of zero indicates no direct chlorine- or bromine-catalyzed depletion

STB-4.B
Global Warming Potential (GWP)
Not Started

A measure comparing a greenhouse gas’s heat-trapping effect with that of carbon dioxide over a specified period; CO₂ has a GWP of 1
