The ozone hole was real. The danger was global. World leaders acted together, and the ozone layer is healing. This World Ozone Day, we celebrate what science and cooperation can achieve. 🌍 #WorldOzoneDay #GlobalAction @unep.org @bas.ac.uk

40 years ago the world agreed the Vienna Convention for the Protection of the Ozone Layer. The Montreal Protocol followed. From science to global action, this is multilateralism at its best. On #WorldOzoneDay we celebrate how this work has protected our environment & health @unepozone.bsky.social

Nigeria is hosting an event to commemorate #WorldOzoneDay recognising officials who have contributed to ozone layer protection in Nigeria. 📅 Sep 16, 2025 ⏰ 09:00 AM West Central Africa Join Zoom Meeting bit.ly/4noraPP #MontrealProtocol #Science #GlobalAction

In 1985, the Vienna Convention set the stage for fixing the ozone hole. It showed the power of countries coming together around science. A model we still need today. #WorldOzoneDay #MontrealProtocol #GlobalAction

Costa Rica 🇨🇷 celebrating hashtag#WorldOzoneDay with an event at Colegio Técnico Profesional de Cañas taking place on 25 September 2025. See flyer for more details. #MontrealProtocol #Science #GlobalAction

Many congratulations and thank you to the Kingdom of Saudi Arabia 🇸🇦 for becoming the 166th and latest party to ratify the Kigali Amendment. Phasing down climate warming HFCs combined with improving energy efficiencies in the cooling sector can avoid significant further warming 🌿 #MontrealProtocol

On this #WorldOzoneDay we also celebrate the science that in the 1970s warned of a looming environmental crisis and the ozone treaties that continue to protect the ozone layer & environment to this day 🌿 Science it not cheap, but its value is beyond measure #MontrealProtocol #Science #GlobalAction

Big discoveries begin with small measurements. In Antarctica, scientists measured the ozone hole, and changed the world. @bas.ac.uk #MontrealProtocol #OzoneLayer

On #WorldOzoneDay we celebrate the achievements of the Montreal Protocol. Thanks to the parties that implement it, the ozone layer is being protected and will eventually heal. For more ozone treaties successes bit.ly/4m5rrFx #MontrealProtocol #Science #GlobalAction

In an increasingly hot world, every fraction of avoided warming is a huge win and one we are proud to celebrate on #WorldOzoneDay. By phasing out nearly all ODSs, the #MontrealProtocol has helped avoid global warming of approximately 0.5-1 °C by mid-century 🌿 bit.ly/4paCiRq #Science #GlobalAction

📅 Webinar TOMORROW 9 September 📢 Free trade zones are designed to enhance efficiency of trade. The webinar will focus on improved customs and inter-agency cooperation to monitor the trade in commodities such as wildlife, chemicals & waste. To register bit.ly/4lYbh0B #GreenCustoms #illegaltrade

This #WorldOzoneDay we also celebrate the 40th anniversary of the Vienna Convention adopted in 1985. The Convention was on a mission: to mobilise global action to collate data & information to save the ozone layer 🌿 Find out how it was done bit.ly/46j3h5T 🎉 #MontrealProtocol #Science #GlobalAction

As #WorldOzoneDay approaches, we will also celebrate the adoption of the Vienna Convention in 1985. Together, the ozone treaties continue to protect life on Earth. True global action heroes - then and now 🌿 For more 👀 ozone.unep.org #MontrealProtocol #Science #GlobalAction

You can't protect what you don't measure. @bas.ac.uk's Jonathan Shanklin explains why long-term monitoring still matters for the ozone layer and for the planet. #MontrealProtocol #OzoneLayer

Science is expensive. But what it gives back to society is priceless. Without long-term funding, there would be no monitoring, no discovery of the ozone hole and no safer future. #MontrealProtocol #OzoneLayer

📢 Every year on 16 September, we celebrate the achievements of the #MontrealProtocol on #WorldOzoneDay. This year, we are highlighting the importance science. This year’s series of posters available in all 6 UN official languages on our WOD2025 dedicated webpage ozone.unep.org/ozon.../from...

Today is #InternationalYouthDay A perfect moment to celebrate the youth shaping our planet’s future. Jonathan Shanklin’s discovery of the ozone hole sparked global action. His message now? Be curious. Be courageous. Keep discovering. #MontrealProtocol #OzoneLayer

Nepal 🇳🇵 becomes the 164th country to ratify the hashtag#KigaliAmendment. In doing so, it commits to phasing down climate warming HFCs and adopting sustainable cooling technology. Countdown to full ratification: 34 parties remaining ozone.unep.org/all-ratifica... #MontrealProtocol #Nepal @unep.org

Parties to the #MontrealProtocol met in Bangkok from 7-11 July at the #OEWG47 to discuss continued and increased ozone layer protection. Many agenda items resulted in draft decisions for #MOP37 3-7 November in 🇰🇪 bit.ly/4nVpz4n #OzoneLayer #ViennaConvention Photo by IISD/ENB | Anastasia Rodopoulou

Still measuring. Still protecting. At Halley Station in Antarctica, scientists like Sabina Kucieba are monitoring our atmosphere year-round: vital work to protect the ozone layer 🌍 #MontrealProtocol #OzoneLayer #ViennaConvention

That's officially a warp! After 5 days and countless hours of discussions, negotiations, divergence and meeting again in the middle, #OEWG47 came to a close earlier this afternoon. Safari njema delegates & see you in Nairobi 🇰🇪 for #MOP37. Photo credit: IISD/ENB | Anastasia Rodopoulou

Women in Cooling – Breaking barriers with #coolskills! On this #WorldRefrigerationDay, we shine a light on women changing the face of the sector. Let’s celebrate those breaking barriers, pushing for progress. More info from #OzonAction implementing partners of the #MontrealProtocol bit.ly/3ZSI677

On #WorldRefrigerationDay, the #KigaliAmendment is a key driver towards #sustainablecooling. Full ratification would increase the demand for more technicians & engineers with #coolskills – a milestone worth aiming for ahead of its 10th anniversary in 2026! bit.ly/3I1dpXf #WREFD25 #MontrealProtocol

The ozone crisis began at the poles but threatened the planet. Science led. Policy followed. And it worked. The ozone layer is healing. From ozone to climate, we already have the blueprint for global action. Let’s use it. #OzoneLayer #ViennaConvention

Ozone protection efforts have contributed significantly to slowing climate change by avoiding an estimated 135 billion tonnes of carbon dioxide (CO2) equivalent emissions from 1990 to 2010. Explore more facts from @unepozone.bsky.social on ozone protection here: ozone.unep.org/facts-and-fi...

The summer solstice ☀️ is the longest day of the year - the day with the most hours of daylight and sunshine making it a potentially very hot day. We need to adopt more #sustainablecooling as a priority. For some, hot days occur all year round bit.ly/4kU28qk 🌿 #MontrealProtocol #KigaliAmendment

📢 The International Network of Women in Cooling (INWIC) has launched a mentorship programme to connect women professionals in the #cooling sector across the world to encourage knowledge exchange and career development in the industry. Find out how you can become a mentee or mentor: bit.ly/4jQdr1l

It's #FreshVeggiesDay today 🥕🍆🍅🥦 But did you know that the #ozone layer helps shield vegetables from over exposure to harmful UV radiation so that they stay healthy and nutritious? It also protects vital insects like bees 🐝 that pollinate the veggie plants! Hurray for the #MontrealProtocol 🎉

The Ozone Secretariat is deeply saddened to hear of the passing of Professor Xiaoyan Tang on 11 June 2025. She was a long serving co-chair of the Environmental Effects Assessment Panel (EEAP) from 1993 until 2012 and made tremendous contributions to the protection of the ozone layer bit.ly/4dYDSk2
