INTERNATIONAL PACT ON OZONE DAMAGE LIKELY IN 1987
An international protocol to severely
limit the use of industrial chemicals which are believed to
damage the earth's protective ozone layer could be signed this
year, officials and scientists here said.
    "By the end of this year, we should have an international
protocol in place we can all be proud of," U.S. Environmental
protection agency officer Bill Long told reporters.
    The chemicals are chiefly chlorofluorocarbons (CFCs) which
are used in refrigeration and making foam plastics, solvents
and aerosols. The earth's upper ozone layer absorbs most of the
harmful ultraviolet rays from the sun.
    The officials and scientists were meeting in Tokyo, ahead
of an international conference on the problem later this month
in either Vienna, or Geneva, Long said.
    Robert Watson, a program manager for atmospheric problems
at the U.S. National Aeronautics and Space Administration said
a protocol should demand an initial freeze on the use of CFCs
by industry. This should be followed by a gradual reduction in
CFC volume until no CFC gases are released into the air, he
said. The U.S. Has already banned use of use CFCs in aerosols
and Japan has asked for voluntary restraint, but both still use
CFCs in industrial processes.
