From Vienna to Kigali: Unveiling the Global Battle Against Ozone Depletion

When CFCs were first introduced in 1930s, they were hailed as miracle chemicals because of their non-toxic, non inflammable and stable nature.
Refrigerants, coolants, Air conditioners, plastic foams and spray cans.
In 1980, scientists reported a large hole in ozone layer over Antarctica where ozone level dropped by 30%.
CFCs were prime suspect.
It was established that one molecule of CFCs was capable of destroying one Lakh molecules of ozone in stratosphere.
vienna convention: It was the first global conference on ozone layer depletion held at Vienna, Austria 1985.
The Vienna Convention for the Protection of Ozone Layer was adopted in the year 1985 and entered into force in 1988.
It acts as a framework for the international efforts to protect the ozone layer.
However, it does not include legally binding reduction goal for the use of ozone-depleting substances (ODS).
Montreal Protocol: The Montreal Protocol was designed to reduce the production and consumption of ozone depleting substances in order to reduce their abundance in the atmosphere and thereby protect the earth's fragile ozone layer. The treaty was opened for signature in 1987 and entered into force in 1989.The developed, as well as developing countries, come under binding progressive phase-out obligations for all the major ozone-depleting substances, including chlorofluorocarbons (CFCs), halons, and the less damaging transitional chemicals such as hydrochlorofluorocarbons (HCFCs).
Kigali Agreement: formally known as the Kigali Amendment to Montreal Protocol
It was adopted at the 28th Meeting of Parties to the Montreal Protocol (MOP28) at Kigali, Rwanda in October 2016.
The agreement lays down a framework for the reduction, and finally phasing out, of the production and use of hydrofluorocarbons (HFCs). #montrealprotocol
