16 September: International Day for the Preservation of the Ozone Layer
The 2016 International Day for the Preservation of the Ozone Layer was observed across the world on 16 September 2016. The theme for the year 2016 is Ozone and climate: Restored by a world united.
The theme for the 2016 International Ozone Day recognizes the collective efforts of the parties to the Vienna Convention and the Montreal Protocol towards the restoration of the ozone layer over the past three decades and the global commitment to combat climate change.
The UN General Assembly in 1994 proclaimed 16 September as the International Day for the Preservation of the Ozone Layer to commemorate the date of the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987.
• Montreal Protocol on Substances that Deplete the Ozone Layer was signed on 16 September 1987.
• It has been recognized as the most successful international environment treaty in history, which has received universal ratification; all countries in the world have now ratified this landmark agreement.
• As of 1 January 2015, the production and consumption of key Ozone Depleting Substances (ODSs) like chlorofluorocarbon (CFCs), CTC halons, Methyl Chloroform and Methyl Bromide have already been phased-out globally.
• As per expert estimates, GHG emissions have been reduced by more than 11 Giga tonnes CO2 equivalent per year through the ODS phase-out activities of the Montreal Protocol.
• The Vienna Convention for the Protection of the Ozone Layer is a Multilateral Environmental Agreement.
• It was agreed upon at the Vienna Conference of 1985 and entered into force in 1988.
• In terms of universality, it is one of the most successful treaties of all time, having been ratified by all United Nations members as well as the Holy See, Niue and the Cook Islands and the European Union.
• It acts as a framework for the international efforts to protect the ozone layer.
• However, it does not include legally binding reduction goals for the use of CFCs, the main chemical agents causing ozone depletion.
