In Brief:

  1. Historical Significance: Commemorates the signing of the landmark Montreal Protocol on September 16, 1987.
  2. Core Purpose: Promotes international cooperation to eliminate ozone-depleting substances (ODSs) such as chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs).
  3. 2026 Theme: "Global Action for a Cooler Planet" highlights the critical link between ozone restoration and climate change mitigation.

Nations worldwide are observing the International Day for the Preservation of the Ozone Layer on September 16, emphasizing the vital role of international environmental policy in safeguarding life on Earth. Established to commemorate the 1987 Montreal Protocol, World Ozone Day serves as a benchmark for international cooperation, having successfully phased out nearly 99% of global ozone-depleting substances. This year's focus highlights how preserving the ozone layer not only blocks dangerous UV-B rays—reducing skin cancer, cataracts, and crop damage—but also directly aids global temperature control. Through initiatives like the Kigali Amendment, expanding sustainable cooling technology and eliminating powerful greenhouse gases remain primary targets for protecting the atmosphere for future generations.
