The Co-Chairs of the Task Force on Inventories, Taka Hiraishi and I, are very pleased to
be here to present to the UNFCCC the IPCC 2006 Guidelines for National Greenhouse
Gas Inventories. These guidelines were produced by the IPCC in response to an invitation
from SBSTA in 2002 in New Delhi for delivery in early 2006. After consideration of this
invitation the IPCC developed Terms of Reference in November 2003 in Vienna and then
selected authors from nominations from Governments.
The 2006 Guidelines are based on the Revised 1996 IPCC Guidelines and two Good
Practice Guidance reports “Good Practice Guidance and Uncertainties Management in
National Greenhouse Gas Inventories”, the GPG2000”, and the “Good Practice
Guidance on Land Use, Land-Use Change and Forestry”, called, “GPG-LULUCF”.
Experience gained in producing national greenhouse gas inventories as well as technical
and scientific development also contributed to the new guidelines.
The 2006 Guidelines consist 5 volumes covering all the sectors.
Volumes 1 and Volumes 2 to 5 are complementary. Volume 1 provides general guidance
on inventory techniques, QA/QC issues, methods to efficiently use available resources
and reporting issues.
The remaining volumes cover the individual source and sink categories in detail.
Volume 2 Energy has few major changes from the existing guidelines, with the addition
of a chapter of CO2 Capture and storage.
Volume 3 – Industrial Processes and Product Use combines the existing Industrial
Processes and Solvent sectors. Guidance is given for additional sectors and extends to
addional greenhouse gases.
Volume 4 – Agriculture, Forestry and Other Land Use combines the existing guidance on
Agriculture (from the GPG 2000) and Land Use Land-Use Change and Forestry from the
GPG LULUCF. This removes the risk of double counting or omissions form the national
estimates. The 2006 Guidelines provide methods for estimating underling parameters for
HWP that can be used to report emissions according to any chosen accounting approach.
Volume 5 – Waste includes improved simple methods to estimate emissions for landfills.
The IPCC believes these guidelines give the most up-to-date and consistent methods for
estimating national greenhouse gas emissions applicable to all countries. The methods in
these guidelines are presented in a number of Tiers. The simplest, Tier 1, also have
default values which enable any one country to estimate its national emissions.
The methods, first developed in the GPG 2000 and GPG LULUCF, ensure high quality
estimates that neither over- nor under-estimate emissions as far as can be judged.
About 250 authors worked to develop the 2006 guidelines. The IPCC would like to thank
all the authors and reviewers without which it would have been possible to produce these
guidelines. Meetings were held in. The IPCC would like also to thank the governments of
Norway, Mauritius, USA, Tanzania, Canada, the Philippines, Russian Federation, and
Australia these countries for their hospitality in hosting meetings of the authors. The Co-
Chairs of the Inventory Task Force would like express their gratitude for the commitment
of the TSU in meeting the tight deadlines for this work.
These guidelines were adopted and accepted at the 25 th session of the IPCC in Port Louis,
Mauritius on 26-28 April. A pre-publication copy of the overview chapter and a CD
containing the entire guidelines has been distributed to parties and can now also be
downloaded from the IPCC Inventory programme website. The IPCC aims to publish the
guidelines in August/September in English and in the other UN languages later in the
