International CFC limits to take effect.

International CFC limits to take effect

Last year, a treaty was drawn up to protect stratospheric ozone by dramatically cutting chlorofluorocarbon (CFC) emissions and freezing halon emissions. Ultimately signed by 47 nations, this Montreal Protocol aims to reduce global CFC emissions to 50 percent below 1986 levels by the year 2000 (SN: 9/26/87, p.196). It now appears those controls on ozone-destroying pollutants will go into effect at the earliest possible date -- next Jan. 1.

Treaty enactment requires ratification by the European Community (EC) and 11 countries representing two-thirds of global CFC consumption. According to the United Nations, 14 countries -- representing more than two-thirds of CFC production -- have already ratified it. Ella Krucoff, in the EC's Washington, D.C., office, says EC ratification will be forwarded to the United Nations "within the next few weeks."
