The In 1994, The United Nations General Assembly proclaimed the 16th September of every year as the International Day for the Preservation of the Ozone Layer, to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer which was signed on 16 September,1987. Simply, this day marks the signature date, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer. The Montreal Protocol is now addressing the accelerated phase-out of HCFCs as per the decision of the 19th Meeting of the Parties (MOP) to the Montreal Protocol in September, 2007. India, being a Party to the Montreal Protocol, has National Strategy to Phase-out of CFCs in the manufacture of Metered Dose Inhalers (MDIs) and it is targeted to eliminate the use of CFCs in MDIs by 2013.
The Scientific Assessment of Ozone Depletion Report 2010, published by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), provides an understandingof the complex linkages between ozone and climate change. The report reaffirms that the Montreal Protocol is working as it has protected the stratospheric ozone layer from much higher levels of depletion by phasing out production and consumption of ozone depleting substances. In 2010, the reduction of ozone depleting substances as aresult of the Montreal Protocol,expressed in CO -equivalent emissions, i.e. about 10 Giga tonnes per year. It is about five times larger than those targeted by the first commitment period 2008-2012 of the Kyoto Protocol.
