Every year on 16 September, International Day for the Preservation of the Ozone Layer or World Ozone Day is celebrated.
The theme of World Ozone Day 2023 is “Montreal Protocol: fixing the ozone layer and reducing climate change.”
In 1994, the United Nations General Assembly had declared 16 September as the International Day for the Preservation of the Ozone Layer.
It is celebrated to mark the anniversary of the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987.
In the history of the United Nations, the Vienna Convention and Montreal Protocol were the first treaties to achieve universal ratification on 16 September 2009.
At the 28th Meeting of the Parties of the Montreal Protocol, signatories of the protocol agreed to end the use of hydrofluorocarbons phase-wise.
The ozone layer is the shield of gas that protects the Earth from the sun’s harmful UV rays.
The depletion of the ozone layer can cause skin cancer in humans and the destruction of the ecosystem.
