International Day for the Preservation of the Ozone Layer 2015, September 16th.








Healing our ozone together



Not so long ago, humanity stood on the brink of a self-inflicted catastrophe. Our use of ozone-depleting substances such as chlorofluorocarbons (CFCs) had torn a hole in the ozone layer that protects us from the sun’s harmful ultraviolet radiation.
But we tackled this challenge. Thirty years ago, the international community signed the Vienna Convention for the Protection of the Ozone Layer. Under its Montreal Protocol, the world united to slash the production and consumption of CFCs and other ozone-depleting substances.
Together, we have succeeded in putting the stratospheric ozone layer on the road to recovery by the middle of this century. As a result, up to 2 million cases of skin cancer may be prevented each year, along with even more avoided cases of eye cataracts.
As we look forward to the adoption of the 2030 Agenda for Sustainable Development, and the effort by governments later this year in Paris to forge a new, collective path forward on climate change, the Montreal Protocol’s success should inspire us.  It shows what we are capable of when nations act together on a global challenge.
But the work of the Montreal Protocol is not yet done. Hydrofluorocarbons (HFCs) have been used as replacements for many ozone-depleting substances. While they do not deplete the ozone layer, they are extremely potent greenhouse gases and will contribute a great deal of warming to our already overheated planet in the coming decades unless we act now.
Many countries are now considering using the Montreal Protocol regime to phase down HFCs.  A political commitment to managing HFCs under the Montreal Protocol could be one of the biggest climate change wins in the lead-up to the Paris climate conference. It will also be another strong victory for multilateral efforts to safeguard our environment. On this International Day, let us ensure that we protect our climate the way we have preserved the ozone layer.

International Day for the Preservation of the Ozone Layer 2014, September 16th



Protecting Ozone, Protecting You, The Mission goes on , 16 September 2014



United Nations Secretary-General's Message on the International Day for the Preservation of the Ozone Layer, 16 September 2014.

Just over a quarter-century ago, the world united to reverse the rapid depletion of the atmospheric ozone layer, which protects Earth from harmful radiation from space. Today, the ozone layer is well on track to recovery within the next few decades.

The Montreal Protocol on Substances that Deplete the Ozone Layer is widely recognized as one of the most successful environmental treaties in history. It establishes legally binding controls on the national production and consumption of ozone-depleting substances, and enjoys universal ratification by 197 parties.

Recent scientific findings reveal the importance of the Montreal Protocol. Without the Protocol and associated agreements, atmospheric levels of ozone-depleting substances could have increased ten-fold by 2050. Concerted action has prevented millions of cases of skin cancer.

The Protocol has also significantly contributed to the fight against climate change, as many ozone-depleting substances are powerful greenhouse gases. Climate change is affecting communities, economies and ecosystems across the globe.  It is essential that we act to mitigate the threat with the same unity of purpose as we have in facing the dangers of ozone depletion.

Let us take inspiration from our efforts to preserve the ozone layer. The Montreal Protocol has shown that decisive action by the international community, including the private sector, can achieve transformative results for the common good. Let us learn from this example and apply its lesson to the urgent task of addressing the climate challenge.

PublicationScientific Assessment of Ozone Depletion : 2014.


 The Earth's protective ozone layer is well on track to recovery in the next few decades thanks to concerted international action against ozone depleting substances, according to a new assessment by 300 scientists.
The Assessment for Decision-Makers, a summary document of the Scientific Assessment of Ozone Depletion 2014, is being published by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO), and is the first comprehensive update in four years.
