Ozone loss is accelerating globally. In 1995 and now again in 1996,
we have experienced record ozone depletions over both the Southern and
Northern hemispheres.
Recently released data from the US National Aeronautics and Space
Administration (NASA) indicate that the 1996 Antarctic ozone hole
peaked at a record 10 million square miles - an area greater than the
total surface area of North America. According to Dr. Rumen Bojkov,
special advisor to the World Meteorological Organization, ozone levels
over the Antarctic are now at the lowest level possible; all of the
ozone subject to depletion by existing chemicals has been destroyed.
New agreements at the 7th Meeting of the Parties in Vienna (1995) on
HCFC and methyl bromide controls achieved little of substance in terms
of protecting the ozone layer through the reduction of chlorine and
bromine loading during the crucial short term period of the next 20
years.
This is unfortunate, for as the UNEP Executive Director has noted at
the 11th meeting of the OEWG that "For Article 2 parties reductions in
the use of methyl bromide and further controls on HCFCs are the two
remaining options for additional action which are both technically and
economically feasible and would significantly lower stratospheric
chlorine and bromine abundances" (UNEP/Ozl.Pro/WGI/l 1/8, para.6)
The following items warrant concern:
- ODS use in developing countries remains in the 200kt/year range,
far above the levels that would allow for rapid reductions in chlorine
loading. This consumption has increased an alarming 45% during the past
decade.
- The Multilateral Fund continues to fund projects utilizing ozone
destroying HCFC technologies, contrary to the decision of the Parties
calling on members to limit the use of HCFCs to applications where
environmentally safer alternatives do not exist. The most recent example
is a five million dollar allocation, approved at the 19th. Meeting of
the Executive Committee of the Multilateral Fund (October, 1996) to the
Multibras Corporation of Brazil, for the elimination of CFCs 11&12
through conversion to HCFC 141-b and HFC HFC-134a in domestic
refrigeration. Multibras is the largest domestic refrigerator
manufacturer in Brazil, and possibly in all of Latin America, and is 41%
owned by the US based Whirlpool corporation.
- Inadequate funding for the Multilateral Fund, withholding of
committed funds to the Fund on the part of Article 2 countries, and
delays in disbursements and implementation by Implementing Agencies mean
that the peak in chlorine loading could be delayed several years.
- Non-compliance is a problem in some regions (e.g. Russian
Federation) and the releases of ODS are significant in terms of the
recovery of stratospheric chlorine levels.
- The ambiguous status of Countries with Economies In Transition
(CEIT) within the Montreal Protocol needs clarification in order to
assist those countries to phase out ODSs.
- Rising CO2 levels and other atmospheric changes are likely to
enhance the ozone depletion effect of stratospheric chlorine and bromine
levels. The Parties must no longer turn a blind eye to the global
warming contributions of ODS replacement technologies, such as HFC-134a.
- Severe technological problems associated with HFC-134a,
especially in the area of servicing of domestic refrigerators in Article
5 countries, may well convince companies to remain with, or even
switch-back to CFCs. This would have negative ramifications for the
ozone layer, as well as for further technology transfers between Article
2 and Article 5 countries.
- Failure to place strict controls on HCFC and MeBr use risks
delaying or slowing the decline in stratospheric chlorine loading once
the peak occurs.
- Illegal trade and consumption of CFCs further endangers the ozone
layer.
These problems mean that further measures need to be taken to speed
up the eventual recovery of the ozone layer. These include:
- Securing the earlier phase out of Methyl Bromide from developed
countries and a radically accelerated phase out in developing
countries.
- Significant tightening and acceleration of controls on HCFCs in
both Article 2 and Article 5 countries.
- Accelerating the phase-out of ozone depleting substances,
particularly CFCs, in developing countries to very close to the turn of
the century.
- Preventing the dumping of obsolete ODS technologies by companies
in Article 2 countries in Article 5 countries.
- Avoiding opening up of loopholes and exemptions to the Montreal
Protocol in all categories of ODSs.
- Adequately funding the Multilateral Fund to ensure that ODS
phase-out projects in Article 5 countries are not delayed due to lack of
funds, and to maintain flexibility for changing to zero-ODP and
zero-global warming technologies for projects utilizing transitional
substances which have been previously approved but not yet implemented.
- Directing the Executive Committee of the Multilateral Fund to
show preferential consideration in funding to ODS replacement
technologies that contribute neither to ozone depletion nor global
warming.
