Adopted in 1985, The Vienna Convention for the Protection of the Ozone Layer is the precursor to the Montreal Protocol. The Vienna Convention is often called a framework convention, because it served as a framework for efforts to protect the globe's ozone layer.
The Montreal Protocol, finalized in 1987, is a global agreement to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances (ODS). ODS are substances that were commonly used in products such as refrigerators, air conditioners, fire extinguishers, and aerosols.
The stratospheric ozone depletion process begins with the emission of halogen source gases by human activities and natural processes. Those emitted by human activities are also called ozone-depleting substances (ODSs). Subsequent steps are accumulation, transport, conversion, chemical reaction, and removal.
The Montreal Protocol on Substances that Deplete the Ozone Layer (the Montreal Protocol) is an international agreement made in 1987. It was designed to stop the production and import of ozone depleting substances and reduce their concentration in the atmosphere to help protect the earth's ozone layer.
Universal ratification of the Montreal Protocol Since it was agreed internationally in 1987 to phase out ozone depleting substances, 197 countries have ratified the Montreal Protocol.

In 1995, the United Nations named September 16 the International Day for the Protection of the Ozone Layer, also known as World Ozone Day . The Montreal Protocol celebrated its 35th anniversary in 2022.
The international treaty called The Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol ) is gradually eliminating the production and consumption of ozone-depleting substances to limit their damage to the earth's ozone layer.
The Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer are major milestones in international environmental law, striving together to protect the environment from any harmful effects of the ozone layer depletion through control, reduction and ...
