Résumé

The provisions of the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer include the requirement that the Parties to the Protocol base their future decisions on the current scientific, environmental, technical, and economic information that is assessed through panels drawn from the worldwide expert communities. To provide that input to the decision-making process, advances in understanding on these topics were assessed in 1989, 1991, 1994, and 1998. The document includes an executive summary containing key summaries prepared during 2001-2002. Extract from the table of contents: controlled substances and other source gases; very short-lived halogen and sulphur substances; polar stratospheric ozone: past and future (trends; causes; chemical-climate modelling); global ozone: past and future; surface ultraviolet radiation: past and future (current understanding, available resources, UV climatology, temporal changes and trends). This document is available on the following Web sites: www.unep.org/ozone; www.unep.ch/ozone.
