Theme for 2026 is “Global Action for a Cooler Planet” with this year also marking 10th anniversary of Kigali Amendment to Montreal Protocol.

About Ozone Layer
- Ozone Layer: Often described as “Earth’s umbrella”, it acts as a protective shield, blocking harmful UV radiation from sun.
- Ozone-Depleting Substances(ODS): Chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs), methyl bromide, halons, and methyl chloroform.
Measures to Tackle Ozone Layer Depletion
- Vienna Convention: Took effect in 1988 and reached universal ratification in 2009.
- Montreal Protocol on Substances That Deplete Ozone Layer: Adopted in 1987, one of the rare treaties to achieve universal ratification.
- Kigali Amendment to Montreal Protocol: Adopted in 2016 to phase down hydrofluorocarbons (HFCs) [HFCs are non-ozone depleting but have huge Global Warming Potential].
