Establishment of a DatabaseEstablishment of a Database on GHG Emission Factors on GHG Emission Factors

UNFCCC, Kyoto protocolUNFCCC, Kyoto protocol

Countries have to submit inventories on regular bases, which are consistent, complete, comparable, transparent, and accurate

Quality of GHG inventories depends on reliable emission factors and activity data

Emission FactorsEmission FactorsEmission factors should reflect

national/regional circumstances.Emission Factors have to be accompanied

with appropriate scientific background information

Emission factors should be documented: “easy” to find and “easy” to check / compare

Objective of the EFDB Project Objective of the EFDB Project To develop a database of emission factors and

underlying information for the purposes of securing and disseminating the most current scientific information on emission factors and assisting in increasing transparency and reliability of national inventories.

Sharing data/information will avoid duplication of research efforts

Comparisons of the underlying information will facilitate the selection of the most appropriate parameters.

Why IPCC EFDB Regional inventory workshops

(IPCC,UNDP,UNFCCC,….)Cuba (IPCC/UNFCCC joint expert meeting, Havana, September 1998)Ghana (UNFCCC expert meeting, Accra, July, 1999)UNDP – (Capacity building to Improve National GHG Inventories

2000-2002 )

An easily accessible public EFDB with supporting scientific information would help improve the quality of GHG inventories in a cost-effective way.

Users of the EFDB Users of the EFDB Inventory compilers (Inventory agencies) in

every Party to the UNFCCCIPCC (for future update of the IPCC

Guidelines)

Nature of the EFDBNature of the EFDB - - more of a “Library” than an “Authority”more of a “Library” than an “Authority”

Users of the EFDB must be able to trust the background information provided with the quantitative value they find. This means that the inclusion/exclusion of new data in/from the database must be controlled.

However, usage of the EFDB information for compiling GHG inventories will always be the full responsibility of the user.

Publishing and distributionPublishing and distribution

Editorial board (review of the EFs)

Publication on the Internet at COP8Updates of the database at fixed intervals (2

to 4 times per year)

Distribute copy on CD ROMFor experts with limited access to the

Internet

Updates once or twice a year

And further …And further …

EFDB is meant as an interactive platform for exchange of knowledge on emission factors

EFDB will only be successful if experts not only browse the database but also propose new emission factors
