<p>An agreement to speed up the phaseout of harmful CFCs
</p>
<p> Getting large numbers of nations to agree on anything,
especially delicate policy issues, is no easy job. But now that
scientists have convinced policymakers that the earth's ozone
layer is in grave danger, governments are moving with unusual
speed and resolve. Meeting in Helsinki last week,
representatives from 86 countries said they favored a total ban
on certain chlorofluorocarbons, man-made chemicals believed to
be destroying the ozone, by the end of the century at the
latest. That goes far beyond the 1987 Montreal Protocol, which
called for a 50% cut in CFC manufacture by 1999.
</p>
<p> At Helsinki the conferees were following the lead of the
U.S. and European Community, which agreed to a similar proposal
earlier this year. The new sense of urgency stems from the
growing recognition of the importance of the stratospheric ozone
layer. It absorbs some of the sun's ultraviolet radiation, which
has been linked to skin cancers and cataracts.
</p>
<p> The Helsinki accord calls on industrialized countries to
create a U.N. fund that would help the developing world adapt
to life without CFCs, which are used, among other things, as
refrigerator coolants and blowing agents for making plastic
foam. Just how this would be done was not specified. Still,
Norway's Environment Minister Sissel Ronbeck announced that her
country would contribute 0.1% of its gross national product, or
about $88 million, if others would do the same.
</p>
<p> Now that nations have agreed on a timetable for meeting the
ozone threat, environmentalists hope that governments will turn
their attention to more intractable ecological problems. At the
Helsinki conference, West Germany's Environment Minister Klaus
Topfer declared that the next urgent task is to put limits on
the emission of carbon dioxide and methane, which are believed
to be contributing to potentially dangerous global warming.
