2006 IPCC Guidelines

for National Greenhouse Gas Inventories

The 2006 IPCC Guidelines for National Greenhouse Gas
Inventories (2006 Guidelines) have now been published.
They are freely available either on CDROM or can be
downloaded from internet.
http://www.ipcc-nggip.iges.or.jp/
The 2006 Guidelines are a significant step forward in theproduction of high quality national estimates of emissions
and removals of greenhouse gases. They are the result of
the work of over 250 authors over 2 years, and have beenextensively peer-reviewed. They build on over 10 years ofinventory development work by the IPCC and experience
gained in using earlier IPCC guidance. The Revised 1996
IPCC Guidelines for National Greenhouse Gas Inventories(Revised 1996 Guidelines), together with the two volumes
on inventory good practice (see Good Practice Guidancebox) currently have to be used by so-called 'Annex I'
Parties to the United Nationas Framework Convention
on Climate Change (UNFCCC) (developed countries).
All other Parties to the Convention should also use theRevised 1996 Guidelines while the use of the Good
Practice Guidance is only encouraged. The UNFCCC isnow considering the new 2006 Guidelines.
The 2006 Guidelines were reviewed by experts andgovernments twice before their acceptance by the IPCC
in Mauritius in April 2006. Over 6000 comments fromaround the world were considered by the authors. Thiswidespread authorship and extensive review has ensured
that the Guidelines contain the best available informationand guidance.
While the 2006 Guidelines were developed in response toa request by the Parties to the UNFCCC they can be used
more widely (see Emission Inventories box). Therefore the2006 IPCC Guidelines have been developed starting from2006 Guidelines - Contents
Volume 1 – General Guidance and Reporting:gives general information on inventory compilation, QA/QC, uncertainty and guidance on the choice of methods.
Volume 2 – Energy:
covers the use, production and transport of energy. Includes coverage of carbon dioxide capture and storage.
Volume 3 – Industrial Processes and Product Use (IPPU):
covers industrial processes such as metal production, petrochemicals and other chemical production. Also covers
the use of products including fluorinated gases.
Volume 4 – Agriculture, Forestry and Other Land Use (AFOLU):
integrates agriculture with all other land uses and changes in land use. Covers agricultural sources such as
livestock, manure management and fertiliser use as well as emissions and removals of greenhouse gases fromdiffering land uses such as forestry, grasslands and settlements.
Volume 5 – Waste:covers the collection, treatment and disposal of wastes including solid wastes, landfills and waste water treatment.

Good Practice Guidance
Good practice is a set of procedures intended to ensure that greenhouse gas inventories are accurate in the sensethat they are systematically neither over- nor underestimates so far as can be judged, and that uncertainties are
reduced so far as possible.

Relationship between General and Sectoral Guidance

the previous 1996 Guidelines, the two volumes of Good
Practice Guidance together with new scientific and technicalknowledge to improve methods and default values ofemission factors and other parameters. The usability of thenew Guidelines in countries with limited resources and/orexperience has been a major consideration in the drafting
process. The choice of methods by inventory compilers
has been structured and made consistent throughout theGuidelines so that inventory compilers with considerable
resources and expertise can use sophisticated methods
while those with fewer resources can still use comparable
good practice methods.
Volume 1 of the 2006 Guidelines provides an overview ofthe management and process of developing inventories
while the remaining volumes give sector specific guidance(see the figure above).

Major Improvements
In addition to the many improvements to default values andindividual methods the 2006 IPCC Guidelines include anumber of major improvements. The table overleaf shows
the categories added since the earlier guidance. The
2006 Guidelines have been restructured compared to theRevised 1996 Guidelines.
Two new sectors have been created by the amalgamationof previously separate sectors:
Industrial Process and Product Use (IPPU)
combining Industrial Processes and Solvent andOther Product Use Sectors
Agriculture, Forestry and Other Land Use (AFOLU)
combining Agriculture with Land Use, Land-Use
Change and Forestry (LULUCF) Sectors.

Emission Inventories
National Greenhouse Gas Inventories are complete estimates of the anthropogenic annual emissions and removalsof greenhouse gases from a country developed source-by-source and sink-by-sink. Inventories are a valuable tool formany users. Not only are they needed for reporting greenhouse gas emissions, they are a key input to policy makers
and also to developing the scientific understanding of climate change. Good knowledge of emissions and removals ofgreenhouse gases:
enables reduction policies to be developed in a cost effective way,
allows different policy options to be compared,
provides a simple monitoring mechanism to monitor implementation of these policies,
are a key input to scientific studies of many environmental issues.

Comparable between countries + Accurate
The two volumes on inventory good practice are: “Good Practice Guidance and Uncertainty Management in National
Greenhouse Gas Inventories” and “Good Practice Guidance for Land Use, Land-Use Change and Forestry". Thesehave now been updated and merged into the 2006 Guidelines.

These combined sectors aim to reduce the risk of double
counting, or omitting emissions, in these areas which
naturally overlap.
By combining the Good Practice Guidance into the main
text the overall result is a clear, more consistent andsystematic manual. Volume 1 provides extended goodpractice guidance applicable to all sectors with an extended
introduction providing an overview of emission inventory
compilation. The guidance on data collection has been
expanded with a dedicated chapter in Volume 1.
The guidance on the treatment of the non-energy useof fuels has been revised with any emissions now being
reported in the Industrial Processes and Product UseSector.
All emissions are now estimated as actual annualemissions. In earlier guidance some methods gave
“potential” emissions, the total emissions from an annual
activity that occur in the inventory year and into the future (forexample emission of methane from landfills can occur for
many years after the material is disposed of in the landfill).
In the AFOLU Sector, previously optional categories, suchas fires, settlements and wetlands, have been consolidated
into the main guidance.
Care has been taken in these Guidelines to ensure that all
the CO2 estimates are of CO2 emitted directly (ignoring any
carbon from the oxidation in the atmosphere of other gases)
thus improving the consistency between sectors.

Other Assistance
While the IPCC cannot provide training directly we areproducing a number of tools and other support for users ofthe 2006 Guidelines. These include:
Emission Factor Database (EFDB): a collection ofemission factors and other parameters to assist users
in finding the most appropriate emission factors for theirnational circumstances. Users can download data for theirown use and contribute by submitting new emission factors.
Inventory Software is now being developed. This
software will implement the tier 1 (and most tier 2) methods
in a simple way while assisting some of the QA/QC
requirements.
NGGIP Website has copies of most of the publications ofthe IPCC National Greenhouse Gas Inventories Programme(IPCC-NGGIP) available. The Technical Support Unit of theIPCC Task Force on National Greenhouse Gas Inventories
is maintaining a list of FAQ and other material to provide
some simple answers to common questions.

Benefits
The 2006 Guidelines are therefore the best available
guidance, to date, on compiling national estimates ofemissions and removals of greenhouse gases. They build
on earlier guidance, over a decade of experience and aworld-wide scientific and technical effort to produce thebest guidelines possible that are applicable to all countries
