The Montreal Protocol which was originally signed on 16 September 1987 and substantially amended in 1990 and 1992 stipulates that the production and consumption of compounds that deplete ozone in the stratosphere are to be phased out in a specified time period. Scientific theory and evidence suggest that, once emitted to the atmosphere, these compounds could significantly deplete the stratospheric ozone layer that shields the planet from damaging UV-B radiation. On 19 December 1994, the United Nations (UN) General Assembly proclaimed 16 September every year to be observed as the International Day for the Preservation of the Ozone Layer to commemorate the same date in 1987, on which the Montreal Protocol on Ozone Depleting Substances - ODS was signed.
ODS are widely used in refrigerators, air-conditioners, fire extinguishers, in dry cleaning, as solvents for cleaning electronic equipment and as agricultural fumigants. Some of the top ranking ODS in India today are ChloroFluoroCarbons (CFCs), Halon, Carbon Tetrachloride, Methyl Chloroform, Methyl Bromide, HydroBromoFluoroCarbons (HBFCs), HydroChloroFluoroCarbons (HCFCs), BromoChloroMethane (BCM). HCFCs are both ozone-depleting substances and powerful greenhouse gases: the most commonly used HCFC is nearly 2,000 times more potent than carbon dioxide in adding to global warming.
To mark this occasion, well known environmentalist Dr L K Dadhich gave a talk on issues pertaining to Global Warming at Sangam University (SU) Bhilwara on 17 Sep 2012.
