International Day for the Preservation of the Ozone Layer
By Resolution 49/114, dated 19 December 1994, the United Nations General Assembly designated 16 September, the day on which the Montreal Protocol was adopted in 1987, as International Day for the Preservation of the Ozone Layer.
The ozone layer, the invisible shield that protects all living things from the sun’s harmful ultraviolet rays, started its decline because of ozone-depleting substances used around the world. By signing the Protocol, governments set a precedent for further international cooperation in dealing with a global environment threat by phasing out ozone-depleting chemicals. South Africa acceded to the Protocol in 1990.
The commemoration of this international day provides a unique opportunity for the international community
- to reflect on the progress that has been made, and
- to remind decision makers and the public of the need to protect this valuable shield that safeguards our planet.
