1. Services to support the update of the EMEP EEA Emission Inventory Guidebook, in particular on methodologies for black carbon emissionsTFEIP meeting, May 14-15 2013Istanbul, TurkeyOle-Kenneth Nielsen Department of Environmental ScienceAarhus University

2. Outline • Introduction • Objective of the project • Tasks • Comments to the draft chapters • Identified issues – general • Final deliverables • Conclusions

3. Introduction (1) • Part of the EU review of its air pollution policy • The review included reviews of the 2005 Thematic Strategy on Air Pollution, the Air Quality Directive 2008/50/EC and the National Emission Ceilings Directive 2001/81/EC (NECD • The setting of new environmental objectives and emission reduction targets in a revised strategy and associated instruments require robust emission inventories

4. Introduction (2) • The joint EMEP/EEA Emission Inventory Guidebook (the “GB”) is the central reference manual used to support countries in estimating emissions under the NECD and the UNECE Long-Range Transboundary Air Pollution (LRTAP) Convention • The NECD provides direct reference to the EMEP/EEA GB in its annex III and it hence relies on the GB to provide methodologies for accurate and complete emission inventories in compliance checking

5. Introduction (3) • The GB requires periodic updates, to ensure that the most up to date knowledge and understanding of emissions is available • This process is lead and managed by the TFEIP • The leaders of the TFEIP expert panels have the overall responsibility for maintaining and developing the chapters within their respective remits • The project was completed in close cooperation with the Task Force on Emission Inventories and projections (TFEIP), EEA and DG Environment

6. Objective of the project • To update specific chapters of the EMEP EEA Guidebook • For the specific tasks defined, this was done by: • A literature review to establish options for the updating of specific chapters • Presentation and discussion at the TFEIP/EIONET meeting in Berne (May 14-15 2012) • Preparation of draft chapters based on the discussion papers and comments received for subsequent review by the TFEIP • Finalisation of the draft chapters following receipt of comments • Inclusion of changed/new emission factors in the Guidebook’s emission factor database (EFDB)

7. Tasks to achieve the objective • Task 1: Review and addition of black carbon methodologies, EFs and reference material • Task 2: Review of consistency between EFs for: PM (all size fractions), HMs, POPs and BC • Task 3: Updates to domestic and other solvent use • Task 4: Updates to small combustion sources • Task 5: Updates to PM fugitive emissions • Task 6: Review and addition of NMVOC emissions from manure management systems • Task 7: Review and addition of ammonia emissions from fertilisers

8. Comments received • Comments were received from: • UK • Germany • Sweden • Hungary • Spain • Ireland • Poland • The Netherlands • Italy • Switzerland • European Aluminium Association • CONCAWE • TFEIP EP leaders

9. Number of comments received • Most reviewers responded using the template  • In the template there was 336 comments • In addition a number of textual comments have been provided in Word documents • Sometimes more difficult to track the issue since there frequently is no mention of page/line number

10. General issues • Harmonisation • Units (Especially BC but also Mg rather than te, etc.) • Terminology (guidebook with capital G, tier with capital T) • Completion of EF tables • Ensuring that all pollutants are either included with an EF or listed as NE or NA • Deletion of all pollutants not included in the reporting template (NFR) • Language • Language needs to be improved

11. Issues related to tiers • Different practice in different chapters • Why only one tier 1 EF table per chapter? • For some chapters (especially “other”) it makes little or no sense to have one tier 1 EF table • Is it useful to maintain the unabated tier 2 tables? • Is it meaningful/helpful to have identical tables both in tier 1 and tier 2?

12. Comments outside the scope of the project • A number of the comments received fell outside the scope of the project • Some of these comments were editorial and were implemented without a significant workload • Others were more substantial in terms of complexity and/or workload • Some proposals required the view of the TFEIP and could not be decided by the project team • The TFEIP will need to decide if and how to address these issues

13. Final deliverables • Final draft chapters • Updated discussion papers • Updated EF database • The used references in the project • The references have been provided to the EEA as a future library • It has not been possible to acquire copies of all current references – should be ensured in any future updates

14. Conclusions (1) • Many improvements to the GB were carried out for the different tasks • Large involvement from TFIEP members in commenting during the entire project • The many comments shows the large interest from the emission inventory community in ensuring the quality of the GB • A number of comments were related to parts of the GB chapters that were not covered by the project

15. Conclusions (2) • It will require continuous efforts to ensure the quality and relevance of the GB • BC guidance should be reviewed in time when more knowledge becomes available • Many chapters, especially within C&I, are still in need of significant updating to bring the scientific level up to date • Future updating should focus on specific chapters (groups of chapters) rather than single pollutants (or group of pollutants) • Improvements should be prioritised for chapters where the use is widespread  user survey to determine which source sectors (EFs) are the ones where most countries depend on the GB

16. Theproject team • Morten Winther • Malene Nielsen • Mette H. Mikkelsen • Katja Hjelgaard • Leif Hoffmann • Marlene Plejdrup • Steen Gyldenkærne • Rikke Albrektsen • Patrik Fauser • Henrik G. Bruun • Members of the project team are in Istanbul • Available for discussion at EP sessions and during breaks
