Detailed explanation-2: -The Montreal Protocol’s objective is to cut down the production and consumption of ozone-depleting substances, in order to reduce their presence in the atmosphere and thus protect the Earth’s ozone layer.
Detailed explanation-3: -Much of the success of the Montreal Protocol, the international treaty guiding recovery of the ozone layer, hinged on an agreement by the world’s nations to phase out the new production of several ozone-destroying chemicals called chlorofluorocarbons, or CFCs.
Detailed explanation-4: -This page provides information on compounds recognized as ozone-depleting substances ( ODS. ODS include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, hydrobromofluorocarbons, chlorobromomethane, and methyl chloroform.
Detailed explanation-5: -Buy air-conditioning and refrigeration equipment that do not use HCFCs as refrigerant. Buy aerosol products that do not use HCFCs or CFCs as propellants. Conduct regular inspection and maintenance of air-conditioning and refrigeration appliances to prevent and minimize refrigerant leakage.
