WORLD OZONE DAY 2025 MESSAGE BY UN SECRETARY-GENERALANTÓNIO GUTERRES
On Ozone Layer DaySecretary-General Says Recovery Shows ‘Progress Possible’ through ScienceUnity
Following is UN Secretary-General António Guterres’ message for the International Day for the Preservation of the Ozone Layerobserved on 16 September:
Forty years agonations came together to take the first step in protecting the ozone layer — guided by scienceunited in action.
The Vienna Convention and its Montreal Protocol became a landmark of multilateral success. Todaythe ozone layer is healing.
This achievement reminds us that when nations heed the warnings of scienceprogress is possible.
Scientists are sounding the alarm once again. We are hurtling towards pushing global temperatures 1.5°C above pre-industrial levelswith devastating consequences.
I urge Governments to fully ratify and implement the Kigali Amendment to the Protocol which commits to phase down hydrofluorocarbons (HFCs) — potent greenhouse gases used primarily in cooling technologies.
And I also urge them to reflect this commitment in their new national climate plans —or nationally determined contributions. These must be aligned with limiting global temperature rise to 1.5°C and cover all sectors and greenhouse gasesincluding HFCs.
Implementing the Kigali Amendment could avoid up to 0.5°C of warming by the end of the century. Paired with energy-efficient coolingwe could double these gains.
Every fraction of a degree matters. Every action counts.
On this World Ozone Daylet’s recommit to preserving our ozone layer and to protecting people and planet for generations to come.

WORLD OZONE DAY 2025 MESSAGE BY UNEP EXECUTIVE DIRECTORINGER ANDERSEN
The theme for this year’s World Ozone Day on 16 September is: From science to global action
The theme aims to highlight the important role of science in alerting the world to emerging issues. Forty years agothe Vienna Convention was adopted as a result of growing concerns raised by the scientific community about the potential catastrophic impact on the ozone layer due to the proliferation of chlorofluorocarbons. With the Montreal Protocol adopted two years laterthe world agreed on global action to phase out ozone damaging chlorofluorocarbons.
World Ozone Day: UNIDO Director General Müller highlights work under Vienna Convention & Montreal Protocol as a beacon for successful climate action
Vienna16 September 2025 – Today we celebrate World Ozone Day. Forty years agorepresentatives from all nations assembled in Vienna to lay the foundation for one of the most remarkable and successful multilateral environmental treaties to date - The Vienna Convention for the Protection of the Ozone Layer. It is the only treaty which ever achieved universal ratification—signed by every country on earth and leading to successful global action to reverse the expanding ozone hole and continuing to protect both the ozone layer as well as the climate to this day.
UNIDO Director General Gerd Müller: “This yearwe mark a truly historic milestone—40 years since the world came together in Vienna to protect our planet’s ozone layer. The adoption of the Vienna Convention and later the Montreal Protocol stands as one of the most successful examples of global cooperation in human history. The crisis was clearand in the face of all the evidence the nations of the world united in urgent action. Faced with mounting scientific evidence of ozone depletionnations acted with urgency and unity. They chose multilateral collaboration over conflictscience over speculationand solutions over silencemaking it the most successful and the only environment treaty adopted by every nation on earth. The Vienna Convention and Montreal Protocol are the blueprints for how we must address today’s global challenges - especially climate change. UNIDOas one of the main implementing agencies of the protocol supports countries and industries worldwide with concrete solutionswith expertiseand with commitment—to build a more sustainable future.”
World Ozone Day is observed every year on September 16marking the importance of the ozone layer and the Montreal Protocol agreement of 1987which protects it. This year also marks the 40th Year of the Vienna Convention for the Protection of the Ozone layerwhich paved the way for the Montreal Protocol. Continue reading...
