A report prepared by the UNEP Environmental Effects Assessment Panel and published in the Journal of Toxicology and Environmental Health. This assessment report provides background information on trifluoroacetic acid (TFA) together with its potential relevance as a risk factor to the environment and human health. In addition, the report draws attention to some of the current concerns of substances controlled by and relevant to the Montreal Protocol.

Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer will achieve the final phase-out of ozone-depleting chlorofluorocarbons (CFCs) this year with the phase-out of CFCs used in metered-dose inhalers (MDIs). This infographic depicts that success.

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.

Summary of the HFC amendment proposals submitted by Canada, Mexico and the United States (North American proposal), India (Indian proposal), the European Union and its member States (European Union proposal) and some island States (Island States proposal)

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.
