1996 IPCC Guidelines
Greenhouse Gas Inventories
The IPCC Guidelines
for National Greenhouse Gas Inventories are approved internationally
and developed through an international process which has included:
- wide dissemination of drafts and collection of comments from national experts;
- testing of methods through development of preliminary inventories;
- country studies which
ensure that methods are tested in a wide variety of national contexts;
- technical and regional
workshops held in Africa, Asia, Latin America, Central Europe and
- informal expert groups
convened to recommend improvements on specific aspects of the methodology.
The IPCC Guidelines
were first accepted in 1994 and published in 1995. UNFCCC COP3 held
in 1997 in Kyoto reaffirmed that the Revised 1996 IPCC Guidelines
for National Greenhouse Gas Inventories should be used as "methodologies
for estimating anthropogenic emissions by sources and removals by
sinks of greenhouse gases" in calculation of legally-binding targets
during the first commitment period.
The Revised 1996 IPCC
Guidelines contain three volumes, each of which provides assistance
to the analyst in the preparation of national GHG inventories. The
Workbook (Volume 2) is also available in French, Spanish and Russian.

the 1995 Guidelines and the Revised 1996 Guidelines.
The series consists of
Reporting Instructions (Volume 1)
provides step-by-step directions for assembling, documenting and
transmitting completed national inventory data consistently, regardless
of the method used to produce the estimates. These instructions
are intended for all users of the IPCC Guidelines and provide
the primary means of ensuring that all reports are consistent
Workbook (Volume 2)
contains suggestions about planning and getting started on a national
inventory for participants who do not have a national inventory
available already and are not experienced in producing such inventories.
It also contains step-by-step instructions for calculating emissions
of carbon dioxide (CO2) and methane (CH4),
as well as some other trace gases, from six major emission source
categories. It is intended to help experts in as many countries
as possible to start developing inventories.
Reference Manual (Volume 3)
provides a compendium of information on methods for estimation
of emissions for a broader range of greenhouse gases and a complete
list of source types for each. It summarises a range of possible
methods for many source types. It also provides summaries of the
scientific basis for the inventory methods recommended and gives
extensive references to the technical literature.
