Since 1995, on 16 September each year, the International Day for the Preservation of the Ozone Layer is celebrated. This date has been designated by the United Nations General Assembly in its resolution 49/114, to commemorate the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer.

This commemoration around the world offers an opportunity to focus attention and action at the global, regional and national levels on the protection of the ozone layer. All UN Member States are invited to devote this special day to promotion, at the national level, of concrete activities in accordance with the objectives and goals of the Montreal Protocol and its Amendment.

Ozone was discovered in 1840. The role it plays in shielding the Earth from ultraviolet radiation from space is a more recent discovery, but by the 1970s scientists had established that various chemicals in widespread use had the capacity to cause ozone depletion. That concern led UNEP (United Nations Environment Programme) and the World Meteorological Organisation to establish a coordinating committee in 1977 to periodically assess ozone depletion.

International negotiations subsequently began on an agreement to phase out ozone depleting substances (ODS), leading finally to the 1985 non-binding Vienna Convention for the Protection of the Ozone Layer.

Then, in 1985 the scientific and political world was taken by surprise, and spurred to action, by the discovery of a hole in the stratospheric ozone layer. The discovery was made by American and British researchers. The recognition by the global community that stronger measures were needed to phase out ODS led to the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer. The Montreal Protocol has been a remarkable success.

The efforts of the world community to protect the ozone layer is a fascinating example of how humanity can act as one to face a common danger.
