Note for the International Day for the Preservation
of the Ozone Layer, 16 September 1998
1. Each 16 September we pause to mark the International Day for the Preservation
of the Ozone Layer, so designated by the United Nations General Assembly in
its resolution 49/114, commemorating the signing of the Montreal Protocol
on Substances that Deplete the Ozone Layer.
2. The main objective of the Montreal Protocol is to protect the thin layer
of ozone in the stratosphere, located between 10 and 50 kilometres above the
Earth, that absorbs all but a small fraction of the harmful ultraviolet radiation
(UV-B) emanating from the Sun and protects all life on Earth.
3. In the early 1970s, scientists discovered that emissions of some human-made
chemicals could deplete the ozone in this layer. The most common of these
are the chlorofluorocarbons (CFCs), halons, hydrochlorofluorocarbons (HCFCs)
and methyl bromide used in refrigeration, air-conditioning, fire-fighting,
metal-cleaning, foam-blowing, soil fumigation and so on. The result would
be more UV-B radiation reaching the Earth?s surface, more skin cancers and
cataracts, reduced plant and animal productivity, poorer air quality, damage
to plastics and an impact on climate.
4. Observations of the atmosphere since then have proved that ozone was
being depleted at a rate of about 5 per cent a decade over the middle and
higher latitudes of the Earth. An ?ozone hole? appeared annually over the
Antarctic.
5. Alarmed by these discoveries, the United Nations Environment Programme
(UNEP) initiated scientific assessments in 1976 and, as certainty grew, started
intergovernmental negotiations to take action to protect the ozone layer.
As a result, the Governments of the world agreed first on the Vienna Convention
for the Protection of the Ozone Layer, in 1985, and then on the Montreal Protocol
on Substances that Deplete the Ozone Layer, on 16 September 1987.
6. The Convention laid down a general commitment to protect the ozone layer.
The Protocol, which was strengthened on four subsequent occasions, obligates
all parties to phase out the ozone-depleting substances according to a specified
timetable.
7. The developing countries are given a grace-period of 10 years. In 1991
the parties to the Protocol established a Multilateral Fund, subscribed to
by the industrialized countries, to meet the increased costs of developing
countries and promote the transfer of alternative substances and technologies.
8. In some areas of global endeavour there has been more talk than action.
In the case of ozone depletion, fortunately, the global community moved with
astonishing speed from concern to discussion, discussion to agreement, and
agreement to action.
9. As a result of the Protocol, the total consumption of CFCs has fallen
by more than 80 per cent since 1986. The consumption of CFCs, carbon tetrachloride,
methyl chloroform and hydrobromofluorocarbons (HBFCs) was completely phased
out by developed countries in 1996, except for a consumption of around 15,000
tons for essential uses approved by the parties.
10. Atmospheric scientists have detected the results of this reduction on
the abundance of these chemicals in the atmosphere. They predict that, given
the full implementation of the Montreal Protocol by all the countries, the
ozone layer will begin its recovery within a few years and complete it by
the middle of the twenty-first century.
11. There are still some problems and challenges to be faced, including
the illegal trade in CFCs. The parties to the Protocol are very concerned
about this problem and have decided that each party should have a licensing
system to import or export CFCs and other chemicals that destroy the ozone
layer.
12. Massive geopolitical and economic changes affected the status of the
former Soviet Union and Eastern Europe after 1989. As a result, the Russian
Federation and several other countries admitted in 1995 that they would be
unable to follow the phase-out schedule for ozone-depleting substances. The
Global Environment Facility, begun in 1991 with ozone depletion as one of
the four global environmental issues within its mandate, came to their rescue,
and has so far approved $120 million to phase out the CFCs in these countries
by the year 2000.
13. Methyl bromide is an ozone-depleting substance used for fumigation of
soils, structures and storage. It is mostly used in soil fumigation for high-value
crops in some countries. Certain countries, such as the Netherlands, have
banned its use because of other toxic properties of this chemical. The parties
to the Montreal Protocol agreed to the phase-out dates of 2005 for developed
countries and 2015 for developing countries. There is considerable danger
that the consumption of methyl bromide could spread to more countries and
to more uses than at present owing to pressure from the manufacturers. The
challenge facing Governments is to stop this in time. Many alternatives are
emerging for methyl bromide in various uses, and the Multilateral Fund has
adopted a $30 million programme to demonstrate these alternatives in developing
countries.
14. The Montreal Protocol allowed a grace-period for developing countries
in recognition of the fact that time will be needed for them to obtain and
introduce alternative technologies. They will be required to implement the
control measures from 1 July 1999 and complete their phase-out according to
schedule. This is a crucial challenge for the next 10 years.
15. This year the celebration of the International Day could focus on further
action needed and themes relevant to the countries, such as ozone-safe products,
consumer action, illegal trade, a consumption freeze in 1999 in developing
countries, creating awareness in small enterprises, alternatives to methyl
bromide, and so on.
16. Business and industry should be encouraged to develop and implement
voluntary guidelines and codes of conduct which can help to promote and disseminate
best practices in the context of environmentally and socially responsible
entrepreneurship, and to develop further those that already exist. To be effective,
such codes must be developed and implemented by business and industry themselves,
for this will ensure their commitment to this process. Equally important,
their credibility with stakeholders requires that such codes stimulate positive
action going well beyond ?business as usual?. Therefore, an essential element
is transparency in the monitoring and public reporting of progress.
17. The following activities, among others, could be undertaken by developing
countries in order to achieve the consumption freeze in 1999:
(a) Disseminate messages from the Ministry of the Environment or the ministry
in charge of ozone issues concerning the importance of meeting the freeze
goal to consumer organizations, industry, other ministries and the public;
(b) Provide support to industry; for example, provide copies of the technical
publications of the United Nations Environment Programme Industry and Environment
and the reports of the Technology and Economic Assessment Panel and its Technical
Options Committees;
(c) Monitor the progress of projects financed by the Multilateral Fund with
industry, firms, enterprises and farms on a continual basis;
(d) Encourage multinational corporations to support the freeze goals in
your country.
18. The following activities could be carried out by all countries:
(a) Establish a licensing system for imports and exports of ozone-depleting
substances;
(b) Promote participation by industry in a smooth and efficient transition
away from CFC-based metered-dose inhalers;
(c) Ban the market placement and sale of virgin CFCs, except to meet the
basic domestic needs of developing countries;
(d) Ratify the London, Copenhagen and Montreal Amendments, as required.
19. The history of the Montreal Protocol has been an inspiring saga of international
cooperation between Governments, scientists, technology experts, industry,
and non-governmental organizations under the auspices of the United Nations
Environment Programme. It is a shining example of how to solve international
environmental problems.
