IPCC Emission Factor Database(EFDB)IPCC TFI Side-event at COP-24
Katowice, Poland
7 December 2019
Pavel Shermanau, IPCC TFI TSUWhat is EFDB?
• Emission Factor Database (EFDB) is an electronic library ofgreenhouse gas emission factors/parameters (EFs):o default values from IPCC Guidelines
o data from peer-reviewed papers
o data from non-peer reviewed publications (governmental reports,industry studies, etc.)• Available for free:o on-line: https://www.ipcc-nggip.iges.or.jp/EFDB/main.php
o off-line: DVD/USB- Version 3.0 (November, 2018) can be downloaded from the web-site

The Web application is the core of this system. New data will be madeavailable in the Web application firstOn-line version of EFDB (web-site)

• Quality of GHG inventories depends on reliable EFs and activity data
• EFs that reflect national circumstances should be used in inventory
compilation• Development of national EFs is costly, time consuming, andrequires much expertise• By sharing data/information EFs can be obtained cost-effectively• An easily accessible public EFDB would help to improve the qualityof national GHG inventories and facilitate data sharing by inventory
compilers, experts, scientists worldwide

EFDB Editorial Boardo The members of the Editorial Board are selected by the Task Force Bureau onNational GHG Inventories from the experts officially nominated bygovernments and observer organizations. In this selection, geographicalbalance as well as balance of expertise should be ensuredo The Editorial Board consists of the following members:a. Two Co-chairs of the Editorial Board
b. Sector experts for each of the sectors*:
i. Energy
ii. Industrial Processes, and Solvent and Other Product Use (IPPU)
iii. Agriculture
iv. Land Use, Land Use Change and Forestry (LULUCF)
v. Waste* Sector experts for Agriculture and LULUCF may work together as Agriculture, Forestry and Other Land Use (AFOLU)
sector in accordance with the 2006 IPCC Guidelines.

Criteria for Inclusion of New Data
Robusto Within the accepted uncertainty, the value is unlikely to change if there
was repetition of the original measurement programme or modelling
activity

Applicableo An emission factor can only be applicable if the source and its mix oftechnology, operating and environmental conditions and abatement andcontrol technologies under which the emission factor was measured ormodelled are clear and allow the user to see how it can be applied

Documentedo Access information to the original technical reference must be provided
to evaluate the robustness and applicability as described aboveEFDB data search
Search options(e.g. Basic search)Specify gas, fuel,type of parameters
Status of search
To narrow down
search results
Details of dataResults can beexported in Excel

IPCC EFDB and UNFCCC process
o In the context of the UNFCCC reporting guidelines for annual inventories forAnnex I Parties
If Annex I Parties lack country-specific information, they could also use EFs or other parametersprovided in the IPCC Emission Factor Database, where available, provided that they candemonstrate that those parameters are appropriate in the specific national circumstances and are
more accurate than the default data provided in the 2006 IPCC Guidelines (Decision 24/CP.19,para 12 Annex I)

o In the context of National communications of non-Annex I Parties (NAI-NC)
Consultative Group of Experts (CGE) agreed on the usefulness of the Emission Factor Databaseand recommended improvement of data quality by enhancement of the sharing of countryspecific emission factors through the Emission Factor Database among NAI Parties, as anelement to be considered in a future revision of the NAI-NC Guidelines (FCCC/SBI/2011/5/Rev.1)

EFDB: Current and Future WorkTSU has been constantly working on improving EFDB:o In May 2018 a new version of EFDB was released whichallows better navigation (categorization for search) and better
functionality for populating the content
o Also it has been upgraded to the latest IT-environment LAMP/MySQL/ PHPo Other features were improved as well (type of parameters, listof gases, sources of data for non-defaults, etc.)
o Next year it is planned to update the off-line version of EFDBResponsibility and Contributiono The responsibility of appropriate use of the EFDB
information will always remain with the users themselveso Success of the EFDB depends on your contribution!

If you work on development of GHG emission factors and would
like to submit your data or give a feedback on thecontent/functionality of EFDB, please share it with the TechnicalSupport Unit (TSU) via e-mail: ipcc-efdb@iges.or.jp
