This synthesis report, coordinated by UNEP, working with more than 45 scientists and experts from more than 35 organizations, concludes that emissions of nitrous oxide are now the most relevant with respect to stratospheric ozone depletion and the third most important gas in terms of climate change. The report shows that if current trends in nitrous oxide emissions are allowed to continue, then it is very possible that ozone layer depletion will continue even with other efforts being implemented.
