This quadrennial Assessment was prepared by the Environmental Effects Assessment Panel (EEAP) for the Parties to the Montreal Protocol. The Assessment reports on key findings on environment and health since the last full Assessment of 2010, paying attention to the interactions between ozone depletion and climate change.

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.

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.
