International Day for the Preservation of the Ozone Layer

The United Nations marks today, the 16th September, as the International Day for the Preservation of the Ozone Layer. In the 1970’s scientists discovered that the ozone layer was under threat from certain gases, such as chlorine and bromine, which had accumulated in the atmosphere. Then, in the 1980’s, a “hole” was discovered in the ozone layer above Antarctica – the region of the earth’s atmosphere which had suffered the severest ozone depletion. Read our fact sheet below for more information on the ozone layer and why the 16th September is such an important date.
