    Progress on Ozone Protection Only the Beginning

    GENEVA, Switzerland, July 12, 2000 (ENS) - Developed countries
    have made impressive progress over the past decade in phasing out
    ozone destroying chemicals. Now they must help developing
    countries do the same, said United Nations Environment Programme
    (UNEP) executive director Klaus Toepfer, on Tuesday.

    "For the next few years, the top priority for all governments
    will be to ensure that developing countries have the
    technological and financial capacity they need for moving to
    ozone friendly chemicals," said Toepfer.

    He was speaking as more than 300 diplomats and experts meet in
    Geneva this week. They are considering ways to prevent further
    damage to the stratospheric ozone layer and preparing for the
    12th Meeting of the Parties to the Montreal Protocol, which will
    be held in Burkina Faso in December.

    The ozone layer is essential for shielding humans, plants and
    animals from the damaging effects of ultraviolet light. It has
    thinned to record levels in recent years. According to the World
    Meteorological Organization, a hole in the ozone above Antarctica
    exceeded 22 million square kilometres (8.5 million square miles)
    during last September's Antarctic spring.

    Near Earth's northern pole, ozone losses of over 60 percent have
    occurred in the Arctic stratosphere this winter, one of the
    coldest stratospheric winters on record, according to the Third
    European Stratospheric Experiment on Ozone sponsored by the
    European Union and the U.S. National Aeronautics and Space
    Administration (NASA).

    Under the 1987 Montreal Protocol, governments agreed to phase out
    chemicals that destroy stratospheric ozone. To date, 175
    countries have ratified the protocol.

    Developed countries have phased out ozone depleting substances
    such as chlorofluorocarbons (CFCs), carbon tetrachloride, methyl
    chloroform and halons.

    UNEP, which provides the Protocol's secretariat, believes that
    the ozone layer can recover, but only if countries continue to
    vigorously enforce the Protocol.

    This week's session of what is known as the open ended working
    group will consider new substances entering the market and
    measures to change from CFC-based inhalers used by asthma
    sufferers.

    It will discuss a proposal from the 15 member European Union to
    speed up developing countries' timeline for phasing out
    hydrochlorofluorocarbons (HCFCs), which are used as substitutes
    for CFCs.

    The proposal is based on the concern that, while much less
    destructive than CFCs, HCFCs do contribute to ozone depletion,
    and other substitutes are now available on the market.

    CFCs were originally invented to serve as refrigerants. Thanks to
    their low toxicity, non-flammability and low price they became
    popular in most refrigeration applications, from domestic
    refrigerators to large refrigeration plants in cold stores and
    supermarkets.

    They became popular in other uses such as foam blowing and
    aerosols. Once it became clear that CFCs were potent ozone
    depletors which would have to be phased out, HCFCs served as CFC
    replacements. HCFCs are currently used in many applications where
    CFCs were formerly used, particularly in the refrigeration sector
    and the manufacture of rigid insulating foam.

    Since technically and economically feasible alternatives to HCFCs
    have become available, the European Commission wants phase out
    dates to be set for the vast majority of uses.

    The European Commission, the executive arm of the European Union,
    is proposing bans for virtually all remaining HCFC uses by 2015 -
    much sooner than the Montreal Protocol's deadlines of 2030 for
    developed countries and 2040 for developing nations. It also
    wants the production of HCFC controlled under the Protocol.

    The Commission believes that the lack of production controls
    creates a risk that HCFC producing companies will heavily promote
    HCFCs even where they could be replaced by other less
    environmentally hazardous substances.

    On Monday, the Protocol's Implementation Committee reviewed
    developing countries' 1998 data on CFCs. Under the Protocol,
    developing countries were committed to freezing CFC emissions at
    average 1995-97 levels during the 12 month period that ended June
    30, 2000.

    They must now reduce rapidly to achieve a 50 percent cut by 2005;
    the deadline for a complete phase out is 2010. Developed
    countries stopped using these chemicals almost completely in
    1996.

    Analysis of the 1998 data showed that CFC consumption in many
    developing countries is already less than or equal to the 1995-97
    baseline, meaning that they are on track to meeting their phase
    out commitments. Eight of the nine developing countries that
    produce CFCs have cut production to below baseline levels.

    The Multilateral Fund, set up to help developing countries phase
    out ozone depleting substances, approved new funding on Monday of
    US$40.5 million for 135 projects and activities in 31 countries.
    Since 1991, the fund has disbursed more than US$1 billion for
    phasing out the consumption of 142,000 tonnes of CFCs and halons,
    and the production of nearly 80,000 tonnes, in over 110
    developing countries.
