English Abstract In this study an international inventory is made of the
emission reduction technologies and potentials for Non-CO2 Greenhouse Gases
(NCGGs) in such a way that they can be used for policy formulation (both
directed at direct implementation and long-term R&D developments). The
report contains descriptions of the state-of-the-art of the technologies,
emission reduction potentials, the costs of emission reduction, and the
prospects for further development and (non-technological) constraints. The
quantitative information on reduction options was processed in a database,
called GENESIS, which can be used to evaluate various reduction technologies
in terms of their reduction potential and costs in a reference scenario.
Both country and regional data were used for the analysis in this study.
Emissions of methane and nitrous oxide contributed in 1990 worldwide to
about 20% of total greenhouse gas emissions (excluding fluorinated gases).
Assuming simple trends, 2020 emissions are estimated to grow with about 40%.
It is technically feasible to reduce these emissions by 30% compared to 2020
projected emissions and stabilise compared to 1990 emissions. Not for all
sectors emission reduction measures have been identified. These numbers may
be slightly higher when these sectors are also incorporated. A considerable
reduction potential exists in developing countries, especially in the long
term. A large share of the identified reduction options can be regarded as
'economic potential', i.e. the benefits off-set the costs at least.
Nevertheless it is unlikely that this 'economic potential' will be fully
explored due to a range of barriers, like juridical, cultural barriers, and
lack of awareness. For developing regions, also a lack of capital may
prohibit implementation of this potential. For CO, NOx and NMVOCs a less
detailed analysis was made. These gases are not part of the Kyoto protocol
and have high uncertainties with regard to their global warming
