International Day for the Preservation of the Ozone Layer

 

What to study?

For Prelims: Key facts on Montreal protocol and Ozone day.

For Mains: Significance of the Ozone layer and the need for protection.

 

Context: The International Day for Preservation of Ozone Layer (or World Ozone Day) is observed every year on September 16 for the preservation of the Ozone Layer.

 

World Ozone Day 2019 Theme: 32 Years and Healing.

 

Significance of the day:

In 1994, the UN General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer.

 

What you need to know about the Ozone layer?

  1. Absorbs most of the Sun’s ultraviolet light which is harmful to human life and other life forms.
  2. Absorbs about 97 to 99% of ultraviolet rays and maintain the ozone-oxygen cycle.

 

Montreal Protocol on Substances that Deplete the Ozone Layer:

  1. Designed to reduce the production and consumption of ozone depleting substances in order to reduce their abundance in the atmosphere, and thereby protect the earth’s fragile ozone Layer.
  2. The original Montreal Protocol was agreed on 16 September 1987 and entered into force on 1 January 1989.
  3. The Protocol includes a unique adjustment provision that enables the Parties to the Protocol to respond quickly to new scientific information and agree to accelerate the reductions required on chemicals already covered by the Protocol.
  4. These adjustments are then automatically applicable to all countries that ratified the Protocol.

 

Target:

Montreal Protocol stipulates that the production and consumption of compounds that deplete ozone in the stratosphere-chlorofluorocarbons (CFCs), halons, carbon tetrachloride, and methyl chloroform-are to be phased out by 2000 (2005 for methyl chloroform).
