16th September each year is celebrated as World Ozone Day to commemorate the signing of the Montreal Protocol in 1987, an international environmental treaty for phasing out of production and consumption of ozone-depleting substances. The theme of World Ozone Day 2021 is “Montreal Protocol — Keeping us, our food and vaccines cool”. The Montreal Protocol on Substances that Deplete the Ozone Layer is the only international environmental treaty universally ratified by all the 198 United Nations member states.

The Government of India has recently decided to ratify the Kigali Amendment to the Montreal Protocol. The Ministry will be working towards developing a national strategy for the phase-down of HFCs, after consultation with all the industry stakeholders. Implementation of HFC phase-down under the Kigali Amendment through the adoption of low-global warming potential and energy-efficient technologies will achieve energy efficiency gains and carbon dioxide emissions reduction — a climate co-benefit.
World Ozone Day reminds us that not only is ozone crucial for life on Earth but that we must continue to protect the ozone layer for future generations as well.
