International Day for the Preservation of the Ozone Layer (informally and simply called Ozone Day) is celebrated on September 16 designed by the United Nations General Assembly

• Every year the International Day for the Preservation of the Ozone Layer is celebrated on 16 September.
• The ozone layer is a very important part of Earth’s atmosphere that is responsible for keeping out potentially harmful ultraviolet radiation. The use of ozone-damaging substances called chlorofluorocarbons (or CFCs) in a wide range of products such as refrigerators, aerosol cans etc, triggered ozone depletion in the atmosphere, becoming visible in the late 1970s and 1980s.

Theme of this year

• The theme for the 2023 International Day for the Preservation of the Ozone Layer is “Montreal Protocol: fixing the ozone layer and reducing climate change.”

History

• On 19 December 1994, the United Nations General Assembly proclaimed 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date, in 1987, on which the Montreal Protocol on Substances that Deplete the Ozone Layer was signed.
