Annex XII -
Reducing global carbon dioxide emissions

A statement to the COP3 by
the INSC
(October, 1997)
The
International Nuclear Societies Council
believes that the world's capacity for
generating electricity from nuclear power
must be increased substantially, if we are to
meet the ambitious targets for reducing
global emissions of carbon dioxide.
A central
tenet of the Third Conference of the Parties
(COP3), to be held in Kyoto in December 1997,
is that carbon dioxide from the combustion of
fossil fuels may cause changes in the earth's
climate. An objective of the Conference will
be to set limits on the emissions of carbon
dioxide.
Little
progress has been made in meeting the target
of the Rio Accord of 1992 to reduce carbon
dioxide emissions to 1990 levels. The trends
over the last 30 years show that, while there
have been increases in emissions from the US
and other OECD countries, most of the
increase has occurred in the developing
world, as those countries strive to develop
market economies and raise their standards of
living (Table 1). Over the period 1990 -
1995, this large increase was offset by a
reduction in emissions from the Former Soviet
Union (FSU) and the Eastern European
countries, because their economies slowed
dramatically as they began to adapt to
market-driven economies. With this phase
ending, it is to be expected that there will
be no further decreases in their emissions,
and there may well be increases, as their
economies start to grow again. Today, about
one quarter of the carbon dioxide emissions
comes from the US, one quarter from the rest
of the OECD, and half from the rest of the
world.
It is now
generally accepted that the global energy
demand will increase by two to three times by
the middle of the next century. Energy demand
in the developing countries is growing by
over 4% per year and already accounts for
over 30% of the global total. Its growth is
likely to continue at a much higher rate than
in the OECD countries.
With these
patterns of growth, reductions of 20% in
emissions from the OECD countries will not
achieve a global reduction in carbon dioxide
emissions. For example, if the OECD countries
were to reduce emissions by 20%, and if the
developing countries were to maintain their
economic development with emissions following
the trends of recent years, then the
resulting global emissions in 2015 would be
30% higher than in 1995.
Thus energy
conservation programs in the countries of the
Organization for Economic Co-operation and
Development (OECD), while highly desirable,
are by no means sufficient. Furthermore, the
major gains in energy efficiency during the
1970s and 1980s have already attacked the
easy targets; further gains will be more
difficult and costly. To have any real impact
on global carbon dioxide emissions, the
principal emphasis must be on energy sources
other than fossil fuels.
Renewable
energy sources can contribute to the
solution. The only commercial large scale
renewable energy in use is hydroelectric
power, which today contributes about 3% of
the global energy supply. It could be
expanded to replace about 3% of the
additional energy demand, if all potential
rivers were developed. However, this does not
seem likely, given concern in many countries
over the environmental impact of new
hydroelectric development. In any event, the
additional energy provided would have little
influence on the total energy picture. No
other renewable energies have yet
demonstrated commercially economic and
reliable energy production on a large scale,
and today they have no measurable
contribution to the global energy supply.
Even with large government development and
operating subsidies, it is doubtful that
these could provide even 10% of the energy
supply within two decades.
Nuclear power
is the only sustainable energy option
available today that can significantly reduce
carbon dioxide emissions. After several
decades of development by governments and
investment by electric utilities, it
currently provides about 7% of the world's
energy supply. Nuclear power is a zero-carbon
energy source that is commercially proven,
safe in operation, does not produce other
greenhouse gases, and contains its waste
products. The technology for permanent
disposal of waste is already well advanced
and needs firm political action to put it
into operation. By using demonstrated
technologies, nuclear fuel reserves in nature
can be extended for centuries of operation.
An important feature of nuclear power is that
the cost of fuel and operation is relatively
small compared with capital cost. Thus, once
built, nuclear power plants produce
electricity at a cost that is relatively
insensitive to inflation or the fluctuations
of prices on the world energy market.
However,
neither the renewable energy technologies nor
new nuclear power plants can compete
economically with pipeline natural gas at
current prices, wherever it is readily
available. In both cases, the initial capital
cost is too high.
Thus, radical
measures will be needed, if the objective
truly is to reduce carbon dioxide emissions.
These measures must be undertaken in the
context that a moral priority for the coming
century will be to help all countries achieve
a reasonable standard of living. To do this,
the developing countries must industrialize
to generate enough wealth to support a higher
standard of living, which in the long term
will reduce their rate of population growth.
This is the only solution that has been
demonstrated to stabilize population growth.
Given all
these factors, and the global thrust to
market economies, the only practical
strategies available to governments in their
initiative to reduce carbon dioxide emissions
are to impose taxes on the emissions, or to
provide subsidies for energy produced from
non-fossil resources, or a combination of
these measures.
Thus, the
International Nuclear Societies Council
believes that governments should acknowledge
the significant impact that nuclear power has
played in limiting global carbon dioxide
emissions. Furthermore, to minimize future
emissions, governments should:
continue
to strive for increased efficiency of
energy use
encourage
the use of renewable energies, where they
can be shown to be economically
beneficial and environmentally acceptable
strongly
encourage the continued operation of
existing nuclear power plants and
facilitate the extension of their
operating life
support
the development and deployment of new,
optimized, cost competitive nuclear power
plants
consider
taxes on carbon dioxide emissions, and
subsidies to energy options that do not
emit carbon dioxide.
