1. EMEP/CORINAIR Atmospheric Emission Inventory Guidebook
Status of the update and restructuring project
Aphrodite Mourelatou (EEA)

2. What happened since last TFEIP/EIONET meeting
UNECE EB welcomed the efforts to update and restructure the Guidebook, Dec 2006
Contract awarded to TNO, December 2006
Kick-off meeting, Copenhagen, January 2007
Inception report to be approved this week
Consultants actively participated to Expert Panel meetings: Transport, Combustion and Industry and to the EGTEI meeting
1 example chapter ready to discuss at this meeting. A few more in the making
Contract awarded by the Commission. TNO main contractor and AEAT sub-contractor
Kick-off meeting: participation: Commission (also JRC) , TFEIP chair, Expert Panel Leaders, IPCC TSU, EGTEI, EMEP, Project Team

3. Work basics
The practical restructuring and update work will be done by the consultants
The final responsibility for the technical content of the Guidebook lies with the TFEIP
Expert panels are the ’scientific conscience’ of the Guidebook and Expert panel members will be the actual ’authors’ of the Guidebook chapters. When expert panel members provide input to the consultants as experts and not as expert panel representatives, they will be paid by the contractants for their contribution.

4. Project organisation Commission Consultant contract EEA
Advisory Editorial Group
EMEP chair / centres
TFEIP Chair / Secretariat

Role of steering group: convened if no agreement

5. Guidebook Structure

6. Guidebook structure Table of content follows NFR for source categories
Link to SNAP classification as process based sub-categories retained
Chapters follow IPCC guidelines as close as possible while respecting particularities of air pollutant inventories
Separate as far as possible numerical information from the main text (stable information) - important for maintenance
Adding a paragraph on gridded data
General chapter on how to estimate spatially disaggregated emission data in the cross cutting issues section and/or in source category chapters

7. Guidebook content Complete source descriptions
Guidance on good practice aspects such as key source analyses, QA/QC systems, uncertainty management and projections
Guidance on methodological choice (incl. decision trees)
Tier 1 methods for all pollutants from all sources
Tier 2 methods for potential key sources
Tier 3 methods for particularly important methods or methods already included in the Guidebook
Emission factors, both default and technology dependant values for a range of process conditions and abatement technologies that might occur in different countries
Uncertainty estimates for emission factors
- [updated more consistent and more complete info on a number of areas....]
- incl. General description about technologies and abatement technologies in use
- TFEIP expert panels input

8. What next?
