On 19 December 1994, the United Nations
General Assembly proclaimed
16 September the International Day for the Preservation of the Ozone
Layer, commemorating the date, in 1987, on which the Montreal Protocol
on Substances that Deplete the Ozone Layer was signed.
States are invited to devote the Day each
year to promote, at the national level, activities in accordance
with the objectives of the Montreal Protocol and its amendments.
The links on the right hand column goes to previous year's celebrations
which provides information and materials that can be used to celebrate
"Ozone Day" in your country, organisation or school.
