IPCC Emission Factor Database (EFDB)IPCC 6th Cycle - IPCC Tools for National GHG Inventories
UN Climate Change Conference
5 December 2018
Katowice, PolandBaasansuren Jamsranjav, IPCC TFI TSUBackground• Quality of GHG inventories depends on reliable emission factors andactivity data
• Desirably, emission factors that reflect national circumstances should beused in inventory compilation• Development of such emission factors is costly, time consuming,
requires much expertise• By sharing data/information, emission factors that take into accountlocal conditions (national circumstances) can be obtained costeffectively―

Users decide if data is suitable in their specific situation• An easily accessible public EFDB with supporting scientific information
would help improve the quality of GHG inventories in a cost-effectiveway• IPCC EFDB is launched in 2002

IPCC EFDB (1)• Library of emission factors/parameters and other relevant data withbackground information
Default values from IPCC Guidelines― Data from peer-reviewed scientific papers― Data from other publications (government reports, industry studies etc.)―• Communication platform to share data and information that can be usedfor estimation of GHG emissions/removals―

Sharing data/information will avoid duplication of efforts

IPCC EFDB (2)• Evolves dynamically: data proposals (e.g. voluntary submissions frominventory compilers, researchers) and data collection efforts (e.g. expertmeetings to collect data)• Open to any data proposals
Data proposals are considered by EFDB Editorial Board for inclusion into
the 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, theConsultative 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, whereavailable, provided that they can demonstrate that those parameters areappropriate in the specific national circumstances and are more accurate
than the default data provided in the 2006 IPCC Guidelines (Decision24/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― 16th Data Meeting (DM16) was held on 14-15 November 2018 in parallelwith 16th Meeting of Editorial Board in Buenos Aires, Argentina. The DM16
focused on data for Land Use, Land-Use Change & Forestry and Waste
sectors―•

Literature search (e.g. peer-reviewed journals, National Inventory
Reports)

Enhancement and improvement of EFDB
• Upgraded new version of the EFDB was released in May 2018
Multi-assignments of IPCC categories and gases― Improvement of data entry process/import functions― Unicode support― Additional gases added to the nomenclature for IPPU sector―••

Other improvements (e.g., publication of “Other Databases” page)
User-interface is being further improved
