Emission Factor Database(EFDB)

Need for Emission Factor Database (EFDB)• IPCC Guidelines contain global or regional default values(mostly for Tier 1) based on the best science when guidelines
were compiled.
• Higher tier estimates need country-specific factors based on:• Situation in country, methods, management etc• Latest science and best practice elsewhere• Latest mitigation being applied• However• it is expensive to measure all these. It would be more efficient to use
appropriate literature or experience in similar situations.
• Emission factors and other parameters may not be easily accessible.

EFDB – Dynamically evolving library• A library:• Documented Emission Factors (interpreted broadly – all parameters)• Peer reviewed• Non-peer reviewed (government reports, industry studies etc.)• In any language (need English abstract)• Available through internet as well as in the form of CDROM
http://www.ipcc-nggip.iges.or.jp/EFDB/• Information about when and where this data may be applicable• Evolves dynamically - new data from inventory compilers, researchers,industry...
• Communication platform for distribution of new research and measurement
data• Data evaluated by Editorial Board (EB)• However the user MUST decide if this is suitable in their specificsituation

Growing importance of EFDB• In the context of revision of the UNFCCC reporting guidelines for Annex IParties, the SBSTA32 welcomed the work of the IPCC to facilitate the useof the 2006 IPCC Guidelines, including its efforts to develop inventory
software and the Emission Factor Database. It invited the IPCC andother relevant organizations to strengthen their efforts in this area.
(FCCC/SBSTA/2010/6, paragraph 76)• In the context of REDD discussion, the SBSTA32 requested the UNFCCC
secretariat to work with the IPCC on promoting the use of the IPCC
Emission Factor Database. (FCCC/SBSTA/2010/6, paragraph 40)• In the context of national communications from non-Annex I Parties(NAI-NC), the Consultative Group of Experts (CGE):• Agreed on the usefulness of Emission Factor Database; and• Recommended improvement of data quality by enhancement of the sharing ofcountry-specific emission factors through the Emission Factor Database among
NAI Parties, as an element to be considered in a future revision of the NAI-NC
Guidelines.

(FCCC/SBI/2011/5/Rev.1)

Enhancement and improvement of EFDB

• Continuing efforts for data collection• Data can be proposed by anyone – welcomed!!
• Meetings to collect data on specific topics are held every year:• Biomass Expansion Factor and forestry data
• Livestock & Soil C in Grasslands and Cropland• Soil N2O• Fugitive emissions and biofuels• Up-to-date data/information relevant to “2013 Supplement to
the 2006 IPCC Guidelines for National Greenhouse Gas
Inventories: Wetlands” will be included.

• Improvement in EFDB user-interface etc.
• Navigability of data search process will be improved.
• User-friendliness of data input process will be improved.

Other activities- Frequently Asked Questions (FAQs)- Expert Meetings- IPCC participation in capacity building activities- Promotion activities- Inventory Internship ProgrammeFAQs – being updated• Answers to frequently asked questions (FAQs)
http://www.ipcc-nggip.iges.or.jp/faq/faq.html• Recently updated as a result of:• Expert Meeting on Uncertainty and Validation of Emission
Inventories(March 2010, Utrecht, the Netherlands)• Expert Meeting on HWP, Wetlands and Soil N2O(October 2010, Geneva, Switzerland)

Expert Meetings• “Software and Use of 2006 IPCC Guidelines for National Greenhouse Gas
Inventories”, Aug 2011, Hayama, Japan• “Use of Facility and Project Information in National GHG Inventories”, Jul
2011, Wellington, New Zealand• “HWP, Wetlands and Soil N2O”, Oct 2010 Geneva, Switzerland• “Use of Models and Measurements in GHG Inventories”, Aug 2010 Sydney,Australia• “Uncertainty and Validation of Emission Inventories”, Mar 2010 Utrecht, TheNetherlands• “National Forest GHG Inventories - A Stock Taking”, Feb 2010 Yokohama,Japan• “IPCC-FAO Expert Meeting Agriculture, Forestry and Other Land Use Data”,
Oct 2009 Rome, Italy• “Revisiting the Use of Managed Land as a Proxy for Estimating NationalAnthropogenic Emissions and Removals", May 2009 Sao Paulo, Brazil

Participation in GHG inventories-related
capacity-building activities• Although it itself does not conduct training, IPCCTFI has actively taken part in many GHG
inventories-related capacity building activities, e.g.:• Japan International Cooperation Agency (JICA) Seminar• Workshop on GHG Inventories in Asia (WGIA)• Training Workshop on the National System for the GHG
Inventory, FAO, Rome, Jan 2011
• CGE GHG Inventory Hands-on Training Workshops for theLatin America and the Caribbean Region, Santiago Chile,Sep 2011

Promotion activities• IPCC TFI has made efforts to promote the useof the IPCC Guidelines through a number oftools and activities, e.g.:• IPCC Open Meeting "Estimation of Greenhouse Gas
Emissions - A Basis of Climate Actions" Aug 2011,
Yokohama, Japan• Primer• Brochures• Banners

Inventory Internship Programme• Established and funded as part of Japan'scontribution to TFI.
• Aims to provide young scientists with opportunities
to familiarise with the IPCC work on
methodologies for national GHG inventories aswell as to contribute to the work of TSU throughapplied studies in relevant inventory-relatedscience.
