World Ozone Day, also known as the International Day for the Preservation of the Ozone Layer, is observed annually on 16 September.
The ozone layer is composed primarily of trioxygen molecules (O3) and acts as a protective shield against harmful ultraviolet (UV) rays from the Sun.
The theme of World Ozone Day 2023 is "Montreal Protocol: Recovering the ozone layer and mitigating climate change".
This theme underlines the important role of the Montreal Protocol not only in protecting the ozone layer but also in addressing and mitigating climate change.
