In the climate change discussion, non-CO2 greenhouse
gases (NCGGs) received official political recognition for the first
time in 1997, when agreement was reached on the Kyoto Protocol. As a
result methane, nitrous oxide, HFCs, PFCs and SF6 now provide
attractive options for detailing the national targets for the
reduction of greenhouse gas emissions meant to control climate change.
This book is the second volume in this area and addresses three main
topics.

Firstly, it documents progress with respect to our knowledge of the
sources and sinks of NCGGs. Information on this subject is essential
in order to reduce the uncertainties in national emissions inventories
which serve as the reference values for commitments of countries in
the framework of the Kyoto Protocol. Secondly, this volume deals with
the control options for the NCGGs and contains a wealth of information
in this area. Emerging technologies here provide business
opportunities, in particular in connection with the flexible
mechanisms for mitigation projects in developing countries which have
been agreed in Kyoto. Thirdly, the book treats the policy
implementation of mitigation options for greenhouse gas emissions.
Tools for control policies, both on the national and international
level, and for different sectors of industry are discussed. National
integrated approaches, including the ones from the United States
Environmental Protection Agency and the Netherlands Ministry of
Environment which both sponsored the conference, provide guidance for
defining the most effective greenhouse gases mitigation plans in
different situations.

This volume is being published in support of the IPCC Process and will
serve as a reference for IPCC''s Third Assessment Report.
