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.
Step 1 - The decomposition of an ozone molecule (O3) into a single oxygen molecule (O) and an oxygen gas molecule (O2). One species breaks into two. Step 2 - The synthesis of two oxygen gas molecules (2O2) from a single oxygen molecule (O) and an ozone molecule (O3). Two species collide.
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.
Oxygen atoms are very, very reactive and they react with another oxygen molecule and form ozone, O3. Ozone and oxygen atoms are continually being interconverted as rays break the ozone and turns into nascent oxygen and oxygen molecules. And the oxygen atom again reacts with the oxygen molecules forms ozone.

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.
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.
Step 1 :O3K1⇌k2O2+O (fast) Step 2:O3+O→k2O2(slow)
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 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.
