IPCC EFDB (1)• Launched in 2002
• Library of emission factors and other parameters with backgroundinformation
Default values from IPCC Guidelines― Data from peer-reviewed scientific papers― Data from other publications (e.g., national reports)―• Communication platform to share data and information that can be used
for estimation of GHG emissions/removals

IPCC EFDB (2)• Evolves dynamically: data proposals (e.g. voluntary submissions fromexperts) and data collection efforts (e.g. expert meetings to collect data)• Open to any data proposals
Data proposals are considered by EFDB Editorial Board for inclusion intothe EFDB
― Criteria for inclusion of new data: robustness, applicability anddocumentation― Contact IPCC TFI Technical Support Unit (TSU) at ipcc-efdb@iges.or.jp―

Growing importance• In the context of National Communications from non-Annex I Parties,
the Consultative Group of Experts (CGE) recommended―Improvement of data quality by enhancement of the sharing of countryspecific emission factors through the IPCC Emission Factor Database andamong Parties not included in Annex I to the Convention(FCCC/SBI/2011/5/Rev.1)• New reporting guidelines on annual inventories for Annex I Parties― If Annex I Parties lack country-specific information, they could also use EFsor other parameters provided in the IPCC Emission Factor Database,where available, provided that they can demonstrate that those parameters
are appropriate in the specific national circumstances and are moreaccurate than the default data provided in the 2006 IPCC Guidelines(Decision 24/CP.19)

How to access EFDB
• Two types of applications:――Web application
Offline application• The web application is the core of the system. New data will be madeavailable in the web application first• The offline application works with MS Access MDB file which contains
the copy of the web database― Can be used on a stand-alone PC― Available for download at the EFDB website

Populating EFDB (2)• Expert meetings to collect data (Data Meetings) have been organizedsince 2008
Focus on specific sectors/categories with the aim to identify, select andapprove data for inclusion into the EFDB
― Attended by experts/data providers and Editorial Board members― 17th Data Meeting (DM17) was held on 12-13 November 2019 in parallelwith 17th Meeting of Editorial Board (11-14 November 2019) in Osaka,
Japan. Focused on data for Agriculture sector.

Enhancement and improvement of EFDB
•Upgraded new offline version of the EFDB was released in November
2019
available for 3 different platforms: Windows, Mac and Linux― does not require any installation procedures (directly executable after
downloading and extracting)―•••More than 500 new data were accepted by the Editorial Board in 2019
for inclusion into the EFDB
Default data of the 2019 Refinement will be included
User-interface is being further improved
