This edition contains the full text of the Vienna Convention for the Protection of the Ozone Layer (1985) in Section 1. Section 2 updates the text of the decisions of the Conferences of the Parties by incorporating the decisions adopted at the Tenth Conference of the Parties in November 2014. The decisions are presented in sub-sections relating to each article of the Convention.

Montreal Protocol parties have successfully replaced 98 per cent of the controlled uses of methyl bromide with alternatives that are more effective and much safer for the ozone layer. This infographic depicts that success.

The depletion of the ozone layer and the consequent increase in UV radiation at the surface of Earth has been an issue for over forty years. Over that period, there has been enormous progress in our understanding of the science behind ozone layer depletion and its recovery, the effects of ozone layer changes on surface UV radiation, and the consequences of changes in UV radiation on humans and the environment. 

In response to Decision XXVI/9, this September 2015 report provides an update from TEAP of information on alternatives to ozone-depleting substances listed in June 2015 XXVI/9 report. The report provides updates considering the specific parameters outlined in the current Decision for various sectors and sub-sectors of use. As these parameters were similar to past Decisions (XXIV/7 and XXV/5), TEAP followed the same methodological approach, where no quantitative threshold or importance of one parameter over others was necessarily assumed.
