The Government of Japan supports the National
Greenhouse Gas Inventory Programme since 1999 bygenerously funding the Technical Support Unit (TSU).

The TSU, which is based at the Institute for Global
Environmental Strategies, Hayama, Japan, provides theday-to-day management and support for the inventory
programme, authors and Task Force Bureau.

The 2006 IPCC Guidelines are available as free download from our web site:
http://www.ipcc-nggip.iges.or.jp/
This site also contains earlier editions of the IPCC Guidelines and supporting material such as the Emissions Factor Database.
A CDROM version is also available for those with problems downloading the files. The Guidelines have been translated into all UN
languages and these are also available on the Internet.

Future activities of the IPCC National Greenhouse Gas Inventories Programme

National Greenhouse Gas
Inventories Programme-NGGIPThe IPCC establishedd the National Greenhouse Gas
Inventories Programmeme (NGGIP) to provide methods
for estimating national inventories of greenhouse gas
emissions to, and removals from, the atmosphere. The
NGGIP also exists to encourage the use of the IPCC’smethodological guidance. The box overleaf summarises
the mandate given to the NGGIP.
The guidance produced by the NGGIP is used by countries
that are Parties to the UN Framework Convention on
Climate Change (UNFCCC) to estimate the emissions andremovals that they report to the UNFCCC. It may be usedby others who want to produce estimates consistent withnational totals. Internationally agreed guidance is needed
so that emission and removal estimates can be compared
between countries and over time. All the IPCC guidance
has therefore been compiled by an international range ofauthors and with an extensive global review process.
The figure overleaf summarises the process of producing
methodology reports. There are two review phases. The
first review is by inventory experts worldwide. The second
review also includes governments. This review system
is needed to ensure the quality and usefulness of the
final products. The documents are produced by authors
nominated by governments and other organisations, andselected in accordance with the IPCC procedures.

All IPCC guidance is available for free download from theNGGIP website (much of it is also available on CDROM):
http://www.ipcc-nggip.iges.or.jp/
The first methodologies were produced by the IPCC inearly 1990s and have been revised since (see a diagram
overleaf titled Development of IPCC Guidelines and GoodPractice Guidance). The Revised 1996 Guidelines for
National Greenhouse Gas Inventories (the Revised 1996
Guidelines), the Good Practice Guidance and Uncertainty
Management in National Greenhouse Gas Inventories(GPG2000) and the Good Practice Guidance for Land
Use, Land-Use Change and Forestry (GPG-LULUCF)(contained in the shaded rectangle on the diagram) areused by developed countries to estimate emissions andremovals, and are recommended by the UNFCCC for use
by all countries.
The 2006 IPCC Guidelines for National Greenhouse Gas
Inventories (the 2006 Guidelines) are the IPCC’s mostrecent guidance on methods and data for developing
estimates of emissions and removals of greenhousegases. They build on earlier guidance, over a decadeof experience and a world-wide scientific and technicaleffort to produce guidelines, applicable to all countries
notwithstanding widely varying levels of resources andexpertise.

The NGGIP has also produced other technical documents,
including:

The NGGIP also produces additional tools to assist
inventory production. These include:“Definitions and Methodological Options to Inventory
Emissions from Direct Human-induced Degradationof Forests and Devegetation of Other Vegetation
Types”

Software for the 2006 Guidelines: This softwareis under development. It will implement the simplest
estimation methods in the 2006 Guidelines andis aimed at those with limited resources and/orexperience. The new software will enable users toproduce greenhouse gas inventory time-series in aconsistent manner.

These and other documents are available at http://www.
ipcc-nggip.iges.or.jp/.

Awareness raising: This will include publicity,material, pamphlets and longer documents, theNGGIP web site and the new 2006 Guidelines
software currently under construction.
Facilitating the use of the Guidelines: TheEmission Factor Database and the software aremajor parts of this support. Work is continuing todevelop and improve the Emission Factor Databasethat is available either over the internet or on
CDROM. In addition there will be more informationon the NGGIP web site, and an introduction to the2006 Guidelines.
Addressing technical issues: Currently the only
activity under this heading is a review of the needfor additional assistance for the Agriculture, Forestry
and Other Land Use Sector focussing on usability.
The IPCC Task Force on National Greenhouse Gas
Inventories (TFI) may take up other issues if theneed arises.

Future activities of the NGGIP will focus on encouraging
and supporting the use of the guidance and can be divided
into three interlocking areas:

Emission Factor Database (EFDB): This is adatabase of greenhouse gas emission factors which
provides inventory compilers and other users with awide range of factors to help them select those thatbest reflect their national circumstances.

Mandate
The current mandate of the National Greenhouse Gas Inventories Programme (NGGIP) was approved by IPCC16(Montreal, May 2000). IPCC19 (Geneva, April 2002) decided to maintain its Task Force on Inventories, co-chaired by
two members of the IPCC Bureau (one from an industrialized country and one from a developing country) with twelve
additional members on the Task Force Bureau (two per IPCC/WMO region). The NGGIP is mandated to carry out thework, as approved by the Panel, on inventory-related methodologies and practices.

2003
2006 IPCC Guidelines for National
Greenhouse Gas Inventories

The Panel decided:

2006

That the IPCC is responsible for assessing and developing inventory methods and practices which are scientificallysound and relevant to all countries, noting particularly the lack of information in developing countries. This includes(a) developing methods for estimating emissions of greenhouse gases (GHGs) by sources and removals by sinks, (b)assessing and developing methods to quantify and to manage uncertainties in the estimates of GHGs, (c) assessing
the scientific literature related to the development of GHG emission factors and management of inventories, (d)disseminating information related to inventory methods and practices, (e) identifying the implications of the different
options in relation to inventory methods and practices and (f) assessing scientific issues related to independentverification,
That the IPCC accepts the responsibility to provide scientific and technical advice on specific questions related toinventory methods and practices at the request of the UNFCCC in accordance with established IPCC procedures …
