This year marks the 30th anniversary of the Vienna Convention for the Protection of the Ozone Layer, an important milestone in the protection of the ozone layer. The International Ozone Day is an annual event that commemorates the date of the signing, in 1987, of the Montreal Protocol on Substances that Deplete the Ozone Layer. In the last three decades, the Vienna Convention and its Montreal Protocol have galvanized 197 nations to work together on phasing out ozone-depleting substances, thus protecting the ozone layer for this and future generations and contributing significantly to global efforts to address climate change.
