The International Day for the Preservation of the Ozone Layer celebrates our planet's fragile atmospheric protector — a thin layer of gas that blocks the Sun's most dangerous rays and makes life on Earth possible.
Established by the UN in 1994, this day commemorates the groundbreaking Montreal Protocol of 1987, one of environmental diplomacy's greatest success stories. The treaty has systematically eliminated ozone-depleting substances worldwide, proving that global cooperation can heal our planet.
The results speak for themselves: the ozone layer is recovering, and the Montreal Protocol continues evolving. Its recent Kigali Amendment tackles climate change head-on by phasing out hydrofluorocarbons, delivering a double win for both ozone protection and climate action.
