Your refrigerator could be too hot for you in a few years from now. Indian refrigerators use CFCs, HFCs or HCFCs are coolants and insulation lining producing substances to maintain low temperature. CFCs are highly ozone depleting and are required to be phased out by the refrigeration and air-conditioning sectors in the developing countries by 2003 as per the Montreal Protocol for the Protection of Ozone Layer, 1987. HFCs and HCFCs are ozone friendly but cause global warming. The Kyoto Protocol of 1997 has labelled them as control substances and they, too, have to be phased out sooner than later.
