  1. 5th Joint UNECE Task Force & EIONET Workshop on Emission Inventories and Projections Lago Maggiore, Italy, October 18 – 20, 2004 Results of CAFE Consultations Wilfried Winiwarter, Janusz Cofala, Zbigniew Klimont, Markus Amann, ...

  2. Outline • Consultations, the RAINS model and the emission inventory process • Findings and specific results from the consultation process • Conclusions and recommendations for future reporting

  3. UNECE / NECD EMEP msc-w ETC/ACC CIAM / IIASA The fate of national inventory data ... C Country U Check for submission, timeliness Check for data consistency (REPDAB) Data comparability Data integration into RAINS model

  4. Optimizing RAINS data • Inventory review (see Klimont, TFEIP Warsaw) • Comparing national submissions to RAINS (emissions, energy balances, other activity data) • Questionnaire to countries • Consultations with countries under the CAFE program • Includes personal contacts with experts

  5. Aims of consultations • Include national information • Identify data gaps • Provide a consistent European dataset • Inform national experts about aims of CAFE process and modelling tools used

  6. Consultations • Visits of 20 country teams, most of them between November 2003 and March 2004 • 4 industrial associations • More than 100 experts involved • Further correspondence by telephone and/or E-Mail

  7. The RAINS model

  8. Findings / experience • Predefined NFR form is very helpful • Even if RAINS structure far more detailed • „Automatization“ of data transfer could not be achieved fully • Aggregated data can not be automatically interpreted • Different interpretation of specific source sectors • Sector „other“: e.g. 1A2f – NOxindustrial combustion  internal combustion engines

  9. Documentation • Important for transparency & to identify national interpretation of NFR • Time consuming to understand • Language • Individual concepts • Advantage of forms • Use of covering notes would be helpful

  10. Finding of consultations • Most striking differences: • Fuel sulfur contents • Traffic models • Activity data (Note: RAINS uses PRIMES) • Inconsistencies/corrections in national data • Structural items • Missing sources in national submissions result in remaining discrepancies to RAINS (e.g., PM emissions from livestock)

  11. Systematic difference: fuel exports • Local requirement: • Knowledge about local air pollution and actual emissions on site • European requirement: • As above, but • National shipping to be reported as national emissions (also off-shore fishing) • Fuel sales to be accounted nationally, independent of where fuel is consumed (tank tourism) • International shipping not to be reported, even if emissions important locally

  12. National inventory RAINS estimate RAINS vs. national inventories, 2000 SO2 NOx VOC NH3

  13. Conclusions (1) • Consultation process was able to provide consistency between RAINS input and national emission data • (even if in some cases iterations were needed) • Also, it supported consistency between countries • A wealth of valuable data was provided by country experts • (Thank you!)

  14. Conclusions (2) • Much time was spent on control technologies, their penetration rates and efficiencies (far beyond mere emission estimates) • Ideally, data transmission forms should serve • The possibilities of the data provider • The needs of the data user • Effort was extremely time consuming, but extremely worthwhile!
