Montreal Protocol Ozone Secretariat
@unepozone
The ozone layer, an invisible shield around the Earth protects all living things from the effects of the sun’s harmful ultraviolet radiation. Through the Protocol’s Kigali Amendment, countries are helping to avoid an estimated 0.5°C of warming by 2100.

Parties to the Montreal Protocol meeting at #OEWG48 are spending the remainder of the time discussing specific contact room papers (CRPs) in more focused contact groups including: strengthening the Montreal Protocol, the Replenishment Task Force report, and the viability of the #MontrealProtocol.
‼️ Be sure not to miss the interesting side events for consideration today and tomorrow in the remaining days of the #OEWG48.

❓ Ever wondered what the Implementation Committee does? It examines submissions from parties on non‑compliance, reviews reports on ozone‑depleting substances, and requests additional information when needed. In short, it ensures that ozone layer recovery remains on track! #OEWG48 #MontrealProtocol
To date, 173 parties have ratified the Kigali Amendment. Let's mark the 10th anniversary by empowering this incredible Amendment to its full potential! More on the KA@10: bit.ly/47Rs6pQ #MontrealProtocol #KigaliAmendment
On the margins of the upcoming #OEWG48 will be numerous side events on topics ranging from substances and emissions of substances controlled under the #MontrealProtocol to energy efficiency and next generation technologies. For event listings and timings: bit.ly/4y0jFE7
Today is World Refrigeration Day. With Europe in the midst of heatwaves, the importance of cooling is clear. The Kigali Amendment is an agreement to phase down HFCs to build a future where cooling protects both people and the 🌏 intelligently & sustainably bit.ly/47Rs6pQ #WRD2026 #CoolIntelligence
Day 4 of the Five Days of Cool Intelligence campaign highlights the essential role of sustainable cold chains in supporting food security, public health and climate resilience bit.ly/4uUChmc #WRD2026 #CoolIntelligence #OzonAction
Day 3 of the Five Days of Cool Intelligence campaign: Sustainable cooling can be undermined if refrigerants leak. Life-cycle Refrigerant Management (LRM) addresses the challenges, supporting a circular cooling economy and strengthens compliance with the Kigali Amendment #WRD2026 bit.ly/4eqrlbc
What is the OEWG? The Open-ended Working Group meets annually to discuss ozone layer protection and draft decisions to be adopted by the Meeting of the Parties (MOP) that meets at the end of the year. The co-chairs for #OEWG48 are Annie Gabriel (Australia) and Leila Akello Gonasa (Uganda).
Day 2 of the Five Days of Cool Intelligence campaign, looks at sustainable cooling and how this does not only depend just on technology, but on how cooling systems are designed, maintained and operated. #WRD2026 #CoolIntelligence #OzonAction unep.org/ozonaction/n...
On Day 1 of the count-down to World Refrigeration Day, OzonAction, an implementing partner of the Montreal Protocol, explores how smart policies create the conditions for sustainable cooling. #WRD2026 #CoolIntelligence #OzonAction www.unep.org/ozonaction/n...
Rainforests play a critical role in maintaining the planet's environmental health 🌿 They are massive carbon sinks that inhale carbon dioxide and release oxygen. These critical lungs need protecting. The Montreal Protocol protects the ozone layer to stop UV damage to plants. #WorldRainforestDay
🍓 🥗 🥐 #SustainableGastronomyDay celebrates food but also how we source and store what we eat. Up to a 1/3 of food is lost or wasted globally due to a lack of reliable cooling. The Kigali Amendment helps strengthen cold chains to reduce food loss. #MontrealProtocol #SustainableCooling
As the Kigali Amendment marks its 10th anniversary this year, HE Abdourahmane Diouf reminded us of our collective responsibility to prioritise its full ratification and effective implementation. For the full statement: bit.ly/4xB8sKc #MontrealProtocol 🌿
Climate impacts are already here. From extreme heat to floods and rising seas, the crisis is no longer distant. But action works — and enforcement is key. 👉 Discover how the Montreal Protocol is delivering real climate results: www.unep.org/ozonaction/n...
On #WorldEnvironmentDay, we often focus on forests, oceans, and wildlife. But one of the most powerful levers for environmental protection lies in the hands of refrigeration and air-conditioning (RAC) technicians. This WED, let’s recognise the people behind sustainable cooling bit.ly/43LTIdE
On World Environment Day, we celebrate one of the clearest examples of successful global environmental action🌿 Nearly four decades on, the Protocol continues to deliver—protecting the ozone layer and contributing to environmental protection. These milestones remind us that multilateralism works 🌍✨
Do you consider yourself a good communicator? The Montreal Protocol—one of the most impactful treaties is looking for a Communications Intern to help shape the next chapter. If you're creative, driven and ready to make a difference—this is your moment. ⏳ Apply by 16 June 2026 💻 bit.ly/4dUzxyU
⁉️ Did you know the Montreal Protocol changed weather patterns ⁉️ A thinning ozone layer enabled more UV radiation to reach Earth's surface. By the 1980s, scientists noted jet streams and rain patterns were changing. But in 2020, @noaa.gov noticed this had stopped thanks to the #MontrealProtocol
The risks of skin cancer rise with increased UV exposure ☀️ Thanks to the Montreal Protocol the ozone layer is recovering & reducing the amount of UV reaching Earth—but the risk isn’t gone. Sunscreen is essential: Use it on 27 May #NationalSunscreenDay & every day! #SunscreenDay #MontrealProtocol
🌍 Africa’s cities are beating the heat—through innovation! From Nairobi to Lagos, smarter cooling is taking shape—supported by global action under the Montreal Protocol 🌿 #AfricaDay #MontrealProtocol
❄️ Training tomorrow’s cooling experts today! OzonAction—an implementing agency of the Montreal Protocol—and ASHRAE have launched a new university course on sustainable cooling including: 📚 Full semester course pack 💡 Project-based learning 🌍 Built for the next generation Available ➡️ bit.ly/3RYGCqI
🌿 Biodiversity depends on balance—from the ground to the sky. The #MontrealProtocol helps protect the ozone layer, shielding ecosystems from harmful UV radiation and supporting the health of plants, pollinators, and wildlife. 🌍 Protecting biodiversity starts with us & above us! #BiodiversityDay
🌍 Protect the ozone layer that 🐝 Protects bees 🍎 To protect our food systems! The Montreal Protocol does all three—by reducing harmful radiation that affects ecosystems we depend on. #WorldBeeDay
Tool developed by the Multilateral Fund—the funding mechanism of the Montreal Protocol—helps developing countries understand their HFC consumption trends and model the impact of the Montreal Protocol and its Kigali Amendment 🌿 www.multilateralfund.org/news/kigali-...
🎯 The success of the Montreal Protocol about accountability, working together, and reporting together. 📊 Data keeps everyone informed, accountable, and on track under the Montreal Protocol. 🔎 Individual country reporting and data can be accessed on our website: ozone.unep.org/countries
