Scientific assessment of ozone depletion: 2018.
Author(s) : WMO (World Meteorological Organization), UNEP (United Nations Environment Programme), NOAA, NASA, European Commission
Type of monograph: Report
Summary
An international agreement known as the Montreal Protocol on Substances That Deplete the Ozone Layer was reached in 1987. Through that agreement and its subsequent amendments and adjustments, many nations of the world have carried out policies to reduce and then phase out their use of ozone-depleting chemicals. The Montreal Protocol also called for the international scientific community to periodically update governments on the latest scientific findings related to the ozone layer. Conducted under the auspices of the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) and co-sponsored by NASA, NOAA, and the European Commission, these periodic "state-of-the-science" assessments have guided policymakers as they strengthened the original provisions of the Montreal Protocol.
The present report, “Scientific Assessment of Ozone Depletion: 2018”, is the latest in a series of reports released every four years.It shows that the concentration of ozone-depleting substances continues to decrease, leading to an improvement in the layer since the previous assessment carried out in 2014.
