Environmental Effects of Ozone Depletion 1991 Update - Panel Report Pursuant to Article 6 of the Montreal Protocol on Substances that Deplete the Ozone Layer Under the Auspices of the United Nations Environment Programme (UNEP)
Description
The Montreal Protocol on Substances that Deplete the Ozone Layer requires, in Article 6, periodic assessments of available scientific, environmental, technical, and economic information. The assessments shall be made every four years. The latest assessments were made in 1989. For the reconsideration of the agreements in the Montreal Protocol in 1992, UNEP decided that the 1989 assessments would be updated, rather than making completely new ones. The present report is such an update of the 1989 Environmental Effects Panel Report, and focuses on developments since 1989.
