Japanese Panel Urges

Chlorofluorocarbon Rules

TOKYO - Japan should regulate domestic production and use of chlorofluorocarb ons, or CFCs, in an international effort to preserve the earth's ozone layer, a panel to the Japanese environment agency chief recommended.

A 21-member panel of environmental experts, headed by Masatoshi Tachi, professor emeritus of Gifu University, also recommended that Japan should implement an international promise made in the 1987 Montreal protocol, calling for countries using fluorocarbons to cut usage in half by 1999.

Japan produces about 10 percent of the total fluorocarbons in the world. Fluorocarbons are used in refrigerants, in aerosol cans as propellants, and in the manufacturing of semiconductor chips. Japanese dependance on CFCs for the chip industry led to a sticking point in the Montreal debate, U.S. sources said.
