The OzonAction Newletter produced by UN Environment OzonAction is a tri-annual publication dedicated to the protection of the ozone layer and implementation of the Montreal Protocol.
Since 1987 the OzonAction Newsletter has played an essential role in providing the excellent record of authentic, policy-relevant and consistent messges that contributed to the progress that Parties to the Montreal Protocol have achieved.
As the international community proudly celebrates the 30th anniversary of the Vienna Convention for Protection of the Ozone Layer, the success story of protecting the ozone layer resonates in all fora. Today the world boasts of having phased out 98 per cent of ozone depleting substances (ODS). However, the use of ODS continues to increase in technologies which are indispensable to life on Earth.English
