OZONE DEPLETING SUBSTANCES

"Delayed CFC Phaseout in Developing Countries Raises Growing Concern," P.S. Zurer, Chem. Eng. News, pp. 25-26, May 8, 1995. This update on the progress of the Montreal Protocol emphasizes the growing tensions between developed and developing countries resulting from the more stringent requirements the former must meet. Developing nations have an additional 14 years to phase out CFCs (2010 versus 1996). A more rapid phaseout would speed recovery of the ozone layer, but this would require additional funding from developed nations, and so far they are not even meeting their present commitments. Little movement is likely until the next meeting of parties to the protocol in November.

Item #d95jul139

"Tighter CFC Substitute Controls Found Feasible," P. Zurer, Chem. Eng. News, p. 8, Mar. 13, 1995. A new series of United Nations assessments finds that tighter controls on HCFCs would help speed recovery of the ozone layer, and they are technically and economically feasible.

Item #d95jul140

"Focus Report: What's Ahead for Methyl Bromide?" Global Environ. Change Rep., pp. 1-3, Mar. 10, 1995. As the November Montreal Protocol meeting approaches, debate over how to handle methyl bromide is becoming more intense. Methyl bromide differs from other ozone depleting substances because the ocean is a significant natural source of the chemical, although there is considerable uncertainty about sources and sinks. Although no phaseout has been negotiated under the protocol, several countries have legislated phaseouts of their own. Recovery and recycling technologies are being developed.
