Outline of the presentation● Common Reporting Format● UNFCCC database● Views on the development of the IPCC emission

factors database1

Establishinｇ a Database on Greenhouse Gas Emission Factors Meeting Report : Annex5

Common Reporting Format (1)● Electronic submission of inventory data in astandardized/uniform format from Annex IParties● General information on methods, sources ofactivity data and emission factors and otherinventory information● Information on recalculations

Common Reporting Format (2)● Comparison of activity data and emission factors

over time● Comparison of implied emission factors amongParties● Quick identification of possible errors and/oromissions in inventory data2

IPCC Guidelines❖Scientific basis❖Reporting framework,
including reporting tables,source category structure,etc.

Common Reporting Format(42 tables)
Summary tables (IPCC)
CO2 equivalent emissions table❖Methods and emission factors❖Sectoral tables (IPCC)❖Sectoral background data tables❖Reference approach (IPCC)❖Feedstock and bunkers tables❖Overview table (IPCC)❖Recalculations table❖Completeness table❖Emissions trends❖Check-list❖❖

UNFCCC reporting
guidelines on annualinventories❖New information
requirements

Future inputs❖Any good practice guidance
adopted by the COP❖Other relevant results of theongoing methodologicalwork(FCCC/CP/1999/7)

The UNFCCC database (1)● CRF Import✦Administrative data (Party, Year, Submission etc.)✦Check CRF structure❖ All inventory data as submitted (“Dirty” database)● Consistency Check✦CRF formulas (IEF, Totals, etc) - Redundancy❖ Reduced set of data eliminating inconsistencies andredundancy (“Clean” database)3

Views on the emission factors database● Purpose● Approach● Users● Features● What should be includedPurpose● Improve national GHG inventory quality andcompleteness● Facilitate the preparation of national
communications from non-Annex I Parties● Improve access to information● Provide a reference source for comparing
national emission factors

Establishinｇ a Database on Greenhouse Gas Emission Factors Meeting Report : Annex5Approach● Review English and non-English language

literature● Ensure broad participation (non-Annex I andAnnex I Parties)● Involve international organisations● Consider small expert meetings to review EFs
data on selective sources/sinks● Phased approachUsers● Near Term

✦Inventory experts (non-Annex I and Annex I Parties)✦Scientific community● Longer term

✦Expert review teams✦Project developers (CDM and JI)✦Corporations (Emissions trading)✦IPCC (future update of inventory guidelines)

Establishinｇ a Database on Greenhouse Gas Emission Factors Meeting Report : Annex5Features● Knowledge base - expert system● Flexible structure to allow for expansion● Flexible queries✦ technology/sources✦ regions/climatic zones● “Simple” quality indicators● User-friendly interface

What should be included● Greenhouse gases● No precursor gases● IPCC source/sink categories● Technologies● Test factors
