Environmental
degradation knows no national boundaries. Sulphur emissions in one country
cause acid rain in another downwind. Depletion of the ozone layer from
CFCs used in one nation can lead to skin cancer on the opposite side
of the world. In an increasingly interdependent world, the United Nations
has a crucial role to play in protecting the global environment and
promoting sustainable development. Consider these achievements:
Earth
Summit
At the Earth Summit -- the UN Conference on Environment and Development,
held in Rio de Janeiro in 1992 -- Government leaders, including 108 heads
of State, adopted Agenda 21, a global plan for sustainable development.
It has since become the basis for many national plans, and over 1,800
cities and towns worldwide have created their own "local Agenda 21". The
UN Commission on Sustainable Development meets annually to review progress
and propose policy guidelines.
In June 1997, "Earth Summit+5", a special session of the UN General Assembly
to assess follow-up at the five-year mark, found that despite progress
in many areas, the global environment continues to deterioriate. Governments
agreed to seek further action -- including on fresh water, energy, transport
and tourism -- but few concrete commitments were made.
Climate
Change
The UN Framework Convention on Climate Change, opened for signing at the
1992 Earth Summit, has been ratified by 177 nations, but few industrialized
countries will meet the voluntary goal of reducing their emissions of
greenhouse gases to 1990 levels by 2000.
In December 1997 in Kyoto, Governments negotiated a Protocol to the Convention
by which industrialized countries would accept legally binding targets
to reduce their collective emissions of six greenhouse gases by at least
5 per cent by 2008-12. The next round of talks, set for October 1999 in
Bonn, Germany, will continue to work out details on emissions trading
and other mechanisms. The Protocol has been signed by over 80 countries.
The Intergovernmental Panel on Climate Change (IPCC), coordinated by the
UN Environment Programme (UNEP) and the World Meteorological Organization
(a UN agency), issued a report in 1995 finding "discernible human influence
on the global climate". Based on the work of over 2,000 leading scientists
from 130 countries, the IPCC, set up in 1988, reviews scientific and economic
research on climate change. Its next major assessment report is due in
2001.
Ozone
Depletion
Industrialized countries have banned production of CFCs as of the beginning
of 1996 under the amended 1987 Montreal Protocol, administered by UNEP.
Developing countries have a 10-year grace period to comply and must freeze
their production and use of CFCs as of 1 July 1999. Schedules are in place
to phase out other ozone-depleting substances.
Acid
Rain
Acid rain in Europe and North America has been significantly reduced under
a landmark 1979 Convention administered by the UN Economic Commission
for Europe.
Hazardous
Wastes and Chemicals
To regulate the nearly 4 million tons of toxic waste that crosses national
borders each year, in 1989 countries negotiated the Basel Convention on
hazardous wastes, administered by UNEP and since ratified by 121 countries.
In 1995 the treaty was strengthened to outlaw the export of toxic waste
from developed to developing countries, which often do not have the technology
for safe disposal. In 1998, over 100 Governments adopted an international
treaty, negotiated under FAO and UNEP auspices, on the sharing of information
on trade in hazardous chemicals and pesticides.
Biological
Diversity
The UN Convention on Biological Diversity, signed at the 1992 Earth Summit
and since ratified by 174 nations, obligates countries to protect plant
and animal species through habitat preservation and other means. Negotiations
are ongoing to finalize a protocol to the Convention to reduce the risks
of transboundary movement of living modified organisms and ensure the
safe use of modern biotechnologies.
Protection of endangered species is also enforced under CITES -- the 1973
Convention on International Trade in Endangered Species -- administered
by UNEP. Countries meet periodically to update the list of which plant
and animal species or products, such as ivory, should be protected by
quotas or outright bans.
Fish
and Marine Resources
Global monitoring of fish stocks is carried out by the UN Food and Agriculture
Organization (FAO), which estimates that 70 per cent of commercial fishing
grounds are depleted or recovering from overfishing.
A UN legal agreement to regulate fishing on the high seas, negotiated
as an outgrowth of the Earth Summit, was adopted in December 1995. Nearly
60 countries have signed the agreement, which aims to prevent overfishing
and ease international tensions over competition for dwindling fish stocks,
but it has been ratified by only 21 of the 30 countries needed for it
to become legally binding.
Marine
Pollution
Oil pollution from ships has been cut by 60 per cent since 1981, after
the adoption of a legal Convention negotiated by the International Maritime
Organization, a UN agency. The treaty, which now applies to more than
85 per cent of the world's merchant fleet, also sets strict controls for
disposal of garbage by ships.
In 1995, Governments adopted an action plan on land-based sources of marine
pollution, and talks have begun for a legal agreement to regulate persistent
organic pollutants, such as DDT,PCBs and dioxin.
Desertification
The UN Convention to Combat Desertification -- which was called for at
the Earth Summit -- became legally binding in December 1996. Desertification,
or the degradation of arid and semi-arid lands, affects the livelihood
and food supply of over 900 million people worldwide, especially in Africa.
Forests
To combat deforestation globally, FAO monitors forest loss and trade in
timber and assists developing countries in managing forests. Some 13 million
hectares of forest -- an area the size of Nepal -- are cut or burned each
year, mostly in developing countries.
The Intergovernmental Panel on Forests, which met for two years under
the UN Commission on Sustainable Development, adopted over one hundred
action proposals in March 1997. To monitor implementation and build consensus
on further steps -- for example, a possible forest treaty -- Governments
set up an Intergovernmental Forum on Forests at the Earth Summit+5 session
in June 1997.
Fresh
Water
A 1997 UN-organized assessment found that one-third of the world's population
lives in countries facing moderate to severe shortages of usable fresh
water; by 2025, that figure may reach two-thirds unless action is taken.
Governments and experts are working toward a consensus on water policies.
Financing
for the Environment
The Global Environment Facility (GEF) -- jointly run by the World Bank,
the UN Development Prgramme and UNEP -- has become the main source of
multilateral lending to developing countries for environmental projects.
In 1998, the GEF was replenished by donor countries with a target of over
$2.75 billion.
