Estimating Emissions  IPCC Guidelines contain global or regional default values (mostly for Tier 1) based on the best science when the 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. Factor from IPCC defaults or national information Activity from national or international statistics 4 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

However, …  It is expensive to measure all the factors used.  Even just for key categories, this would often would be prohibitive.  It would be more efficient to use values developed elsewhere for similar circumstances.  Emission factors and other parameters may not be easily accessible.  Data may be in the appropriate peer-reviewed literature, but this is not always widely accessible.  Other data may be in less easy-to-find reports. 5 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

The Emission Factor Database  The IPCC Emission Factor Database (EFDB) aims to:  Be a library of parameters useful to inventory compilers:  Both peer reviewed and other reports;  Provide sufficient information to judge whether the data may be applicable to specific circumstances;  Give references to source documents so users can judge whether the data can be used in their situation;  Be freely available to all:  Web version as well as CD;  Allow anyone to provide data to share with other users:  Data evaluated by Editorial Board;  Users are responsible for checking that data are appropriate to their circumstances. 6 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

The Growing Importance of the EFDB  In the context of revision of the UNFCCC Annex I reporting guidelines, the SBSTA32 welcomed the work of the IPCC to facilitate the use of the 2006 IPCC Guidelines, including its efforts to develop inventory software and the Emission Factor Database. It invited the IPCC and other 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 the Emission Factor Database; and  Recommended improvement of data quality by the enhancement of the sharing of country-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) 7 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

Data contained in the EFDB  At present, the EFDB contains the IPCC default data (from the Revised 1996 IPCC Guidelines, IPCC good practice guidance reports and the 2006 IPCC Guidelines).  Additional data from the global scientific and inventory society are also included.  New data will be evaluated for acceptance by the EFDB Editorial Board according to the following criteria:  The EFDB should assist countries in producing inventories that are neither over- nor underestimates so far as can be judged and in which uncertainties are reduced as far as practicable.  To this end, the data are assessed by the Editorial Board to see if they are robust, applicable and documented  This is not a full scientific review. 8 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

How Data can be Submitted  The IPCC welcomes data proposals from everyone.  The website has details and forms with single data and bulk data entry but…  The simplest way is to send an with details to TSU with details at: nggip-  After receipt by TSU:  Data are reviewed by the Editorial Board (EB)  The EB contact the data provider for more information  If the data meet the criteria they are published in the database. 11 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

EB Criteria for New Data  Robust  Within the accepted uncertainty, the value is unlikely to change if there was repetition of the original measurement programme or modelling activity.  Applicable  An emission factor can only be applicable if the source and its mix of technology, operating and environmental conditions and abatement and control technologies under which the emission factor was measured or modelled are clear and allow the user to see how it can be applied.  Documented  Access information to the original technical reference must be provided to evaluate the robustness and applicability as described above. “Properties” 12 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

Robustness  Specific issues concerning robustness are, for example:  Are the measurement techniques including raw data validated and/or verified?  Are the modelling techniques including supporting data validated and/or verified?  Is the conversion (if any) from model assumptions or measurement conditions to annual or other forms of emission factors or other parameters sufficiently explained and justified?  Is an uncertainty assessment on the emission factor or other parameter presented?  Sufficient documentation (provision of access to technical references) will help. 13 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

Robustness 14 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

Applicability – “Properties” are Crucial  “Properties” define what EFDB users might see as important information in order to judge whether the data are suitable for their inventories.  Five types of “properties”:  Technologies/practices  Parameters/conditions  Region/regional conditions  Abatement/control technologies  Others. 15 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

Applicability – “Properties” are crucial 16 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

Documentation  Sufficient information on technical references, for example:  Scientific or technical publication in an internationally available journal  Report or book with an ISBN.  A URL where the technical references are available will be quite helpful. 17 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

Documentation 18 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

Enhancement and Improvement  Continuing efforts for data population:  The IPCC welcomes data from anyone  Meetings to collect data are held, in principle, twice every year  Up-to-date data/information relevant to “2013 Supplement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories: Wetlands” will be included.  Improvement to the EFDB user-interface, etc.:  Navigability of data search process will be improved  User-friendliness of data input process will be improved. 19 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)

Summary  The EFDB is a library of data that may provide more accurate parameters for your national inventory.  Users MUST check themselves whether data are applicable to their circumstances.  The IPCC is actively requesting anyone with suitable data to submit it.  Data will be assessed for robustness, applicability and documentation – not a full scientific review.  The IPCC is planning improvements to the EFDB. 20 Training Materials for National Greenhouse Gas Inventories Consultative Group of Experts (CGE)
