chlorofluorocarbons (CFCs)

greenhouse gases. Compounds which contain chlorine, fluorine and carbon often together with hydrogen, used for the manufacture of solvents, aerosols, refrigerants and plastic foams; they cause ozone depletion in the stratosphere and absorb long-wave radiation.

'The country has been at the forefront in its endeavours to phase out use of Ozone Depleting Substances (ODSs) because, ridding the world of 13 different ozone-depleting substances (ODSs), including hydro-chloro-fluoro-carbons (HCFC) and chloro-fluoro-carbons (CFC), is critical to protecting the ozone layer, which protects all life on earth from adverse fallouts of the ultraviolet (UV) radiation from the sun and its spill-over effect of environment,' said an official of the ministry of the climate change.
