The International Day for the Preservation of the Ozone Layer is observed annually on September 16. The United Nations General Assembly declared this date in 1994 to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987. This treaty became the first in history to achieve universal ratification in 2009, underscoring its global importance. The observance highlights the ongoing efforts to protect the ozone layer, which shields life on Earth from harmful ultraviolet radiation. The 2025 theme, “From science to global action,” emphasises the critical link between research and international cooperation.
