World Ozone Day is celebrated on 16th September. The theme for 2020 is Ozone for life: 35 years of ozone layer protection. It marks 35 years of the Vienna Convention.
Inger Anderson, Executive Director of UNEP, explains how the decisive global response to the ozone layer depletion has become a model of international cooperation. World Ozone Day shows that collective decisions and action, guided by science, are the only ways to solve major global crises.
On 19 December 1994, the General Assembly of the United Nations declared September 16th as 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.
The Montreal Protocol was signed by the United Nations and 45 other countries on September 16, 1987, on substances that deplete the ozone layer. This day is observed annually as the International Day to Protect the Ozone Layer.
The ozone layer is the general term for the high ozone concentration observed in the stratosphere about 15 to 30 km above the surface of the earth. Ozone is a gas that is made of three oxygen atoms O3. The ozone layer covers the whole world and protects us from the sun by absorbing harmful UV B radiation. We would be more vulnerable to weakened immune systems, cataracts, and skin cancer if this shield weakens.
It is very important to protect the ozone layer. The ozone-depleting Substances are Chlorofluorocarbons (CFCs), Hydrochlorofluorocarbons (HCFCs), Halons, Methyl chloroform, Methyl bromide, Carbon tetrachloride.
