Shridhar University Pilani Rajasthan Celebrates International Ozone Day
The Montreal Protocol is a landmark international agreement designed to protect the stratospheric ozone layer. The treaty was originally signed in 1987 and substantially amended in 1990 and 1992. The Montreal Protocol stipulates that the production and consumption of compounds that deplete ozone in the stratosphere are to be phased out in a specified time period.
- (1888PressRelease) September 20, 2011 - 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 ODS are ChloroFluoroCarbons (CFCs), Halon, Carbon Tetrachloride, Methyl Chloroform, Methyl Bromide, HydroBromoFluoroCarbons (HBFCs), HydroChloroFluoroCarbons (HCFCs), BromoChloroMethane (BCM). The Ozone Depleting Potential - ODP of a compound "x" is defined as the ratio of the total amount of ozone destroyed by a fixed amount of compound x to the amount of ozone destroyed by the same mass of CFC-11. The number and nature of the halogen has effect on ODP in the sense that bromine containing halocarbons usually have much higher ODPs than chlorine containing ones.
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. For the 17th International Ozone Day that was observed on September 16, 2011 the theme was "HCFC Phase-out: a unique opportunity"
Addressing the students at Way to Transform Shridhar University Pilani Rajasthan, Prof BR Natarajan Pro Vice Chancellor of the University highlighted the significance of the day in the context of the global ecosystem. He urged them to take up the challenges of developing cutting-edge technologies that not only eliminate ozone-depleting compounds but do so in a way that lowers energy costs and maximizes climate benefits.
Considering that Hydrofluorocarbons HFCs which do not deplete the ozone layer are fast replacing HCFCs, Prof Natarajan cautioned that one should not forget that HFCs are indeed highly potent greenhouse gases. Students enthusiastically participated in the proceedings sharing their opinions and resolved to do their best in this context.
It is indeed high time for all in India today to remember Environmentalist Jim Fowler quote - Our challenge for the future is that we realize we are very much a part of the earth's ecosystem, and we must learn to respect and live according to the basic biological laws of nature.
