Item #d90may64

At a March 1990 technical committee meeting in Geneva on the Montreal Protocol, delegates generally agreed to ban entirely, by the year 2000, the five CFCs currently under the protocol, an additional 10 fully halogenated CFCs and carbon tetrachloride. This strengthening of the original provisions will become official if approved at a ministerial level meeting of signatories to the protocol to be held in London in June. There is still disagreement over methyl chloroform; the United States, the EEC and Nordic countries all support a substantial cut by the year 2000. Another significant outcome of the Geneva meeting was the agreement by industrial nations to subsidize the technology necessary for developing countries to switch to ozone-safe substances. A working session in May will determine who is going to pay whom; costs are estimated at $100 million to over $200 million, depending on whether Brazil, India and China are included. For more details see New Scientist, p. 22, Mar. 24, 1990; Intl. Environ. Rptr., p. 143, Apr.; or Chem. Eng. News, pp. 5-6, Dec. 4.
