THE UN CONVENTION ON CLIMATE CHANGE
The United Nations Framework Convention on Climate Change (UNFCCC)
was signed at the 1992 Earth Summit in Rio by 154 nations. The Earth
Summit was a major gathering on the Environment and Development
where, in addition to the FCCC, the nations of the world adopted
the Biodiversity Convention, the Agenda 21 and other documents.
The FCCC entered into force on 21 March 1994 after ratification
by 50 signatories and was ratified by 181 countries which are therefore
called 'Parties to the Convention'. Parties meet regularly at the
Conference of the Parties (COP) to review the implementation of
the Convention and continue talks on how best to tackle climate
change. The FCCC's status as a framework convention means that so-called
protocols can be added to specify reduction targets or particular
measures to reduce greenhouse gas emissions.
THE ULIMATIVE OBJECTIVE
The FCCC's ultimate objective is "the stabilisation of
greenhouse gas concentrations in the atmosphere at a level that
would prevent dangerous anthropogenic interference with the climate
system".
A "sustainable level" has not been defined by the FCCC, but climate
scientists and politicians have suggested thresholds of 450 or 550
ppm. If no major cuts are made, atmospheric concentrations of greenhouse
gases are projected to rise far beyond these "sustainable thresholds"
within the next few decades.
PRINCIPLES
The Convention is based on four main principles:
Equity: The global climate and the atmosphere belong equally
to every human being. Until now, emissions have occurred mainly
in Europe and North America. These countries are responsible for
85 percent of the human-induced carbon dioxide in the atmosphere
today.
Precautionary action: All climate science is based on estimates
with associated uncertainties. However, Parties must act now to
protect the climate and cannot wait until they have absolute scientific
proof of what exactly the impacts of climate change will be.
Efficiency: Policies and measures to deal with climate change
should be cost-effective so as to ensure global benefits at the
lowest possible cost.
Sustainable Development: the exact meaning of this principle
is still disputed, but it the UN described it as "development which
meets the needs of the present without compromising the ability
of future generations to meet their own needs".
The Convention divides countries into two groups: those who are
listed in Annex 1 of the Convention and those who are not (known
as 'non-Annex 1 Parties'). Annex 1 Parties are the industrialised
countries, who have historically contributed the most to climate
change. For example, North America and the EU are jointly responsible
for 85 per cent of the man-made carbon dioxide in the atmosphere
today.
Accordingly, the FCCC called only on Annex-1 Parties to stabilise
their greenhouse gas emissions at 1990 levels by the year 2000.
This aim, which was not legally binding, was only fulfilled by three
Parties in the EU, plus some countries in Central and Eastern Europe
(whose emissions have fallen substantially due to the breakdown
of economies after 1990, resulting in less industrial production).
