World Ozone Day is observed globally on September 16 every year to commemorate the signing of the Montreal Protocol.
The International Day for the Preservation of the Ozone Layer is held annually to celebrate the success of the Montreal Protocol, which has successfully phased out 99 percent of ozone-depleting substances. The day was proclaimed by the UN General Assembly in 1994 to raise awareness about the importance of the ozone layer in protecting life on Earth from harmful ultraviolet radiation. For the year 2026, the global theme is Global Action for a Cooler Planet, highlighting the ongoing efforts to address climate change through the Kigali Amendment.
The Montreal Protocol on Substances that Deplete the Ozone Layer was signed in 1987. It is widely considered one of the most successful international environmental treaties and is overseen by the Ozone Secretariat under the United Nations Environment Programme (UNEP).
