Korea fulfilled its obligation to cut the production and use of ozone-depleting substances by 50 percent last year in accordance with United Nations regulations, the government said Wednesday (Sept. 13).

Korea joined the Montreal Protocol in 1992, an international agreement designed to protect the ozone layer that took effect in 1989. The protocol aims to phase out the production and use of chlorofluorocarbon (CFCs) and other depleting substances.

Korea cut the production and use of such substances as freon gases and halon by 65 percent and 75 percent, respectively, last year, more than fulfilling its duty to decrease them by 50 percent of the standard amount under the pact, according to the Ministry of Commerce, Industry and Energy.
