Montreal Protocol

Show Summary Details

Quick Reference

The treaty on ‘Substances that Deplete the Ozone Layer’, drawn up in 1987 by the United Nations Environment Programme (UNEP) to phase out the production and use of various substances, notably the chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), which have a deleterious affect on atmospheric ozone and thus create the ozone holes. The initial list of substances has subsequently been increased through various amendments. Revisions agreed in 2007 bring the dates for the elimination of HCFCs forward by ten years: to 2020 for industrialized countries and 2030 for developing countries.
