A Guide to Information on Greenhouse Gases and Ozone Depletion
Published July 1988 through June 1999



Item #d89jan1

The Montreal Protocol on Substances That Deplete the Ozone Layer took effect on January 1, 1989, as expected. By the end of 1988, 28 countries had either ratified the protocol or acceded to it, an equivalent action. Restrictions on the production and consumption of chlorofluorocarbons (CFCs) and halons will begin July 1, 1989. Consumption of CFCs is to be reduced by 50% by 1999, and halon levels are to be frozen. Many environmental organizations, countries and the United Nations Environment Program, the main coordinator of the protocol, are urging a more stringent agreement in the light of recent evidence of increased ozone depletion.

Information on the status of the protocol is available through the United Nations Treaty Office in New York City (212-963-8137). See Global Climate Change Digest, NEWS, Aug. 1988 and Dec. 1988. A list of countries involved and their status was printed in the Friends of the Earth newsletter Atmosphere, Fall 1988 (see PERIODICALS, this Global Climate Change Digest issue--Jan. 1989).
