3. 10 May 2010EMEP/EEA Guidebook and the Netherlands Emission Register3 Introduction Comparison between: the 2009 EMEP/EEA Guidebook (GB) and the Netherlands Emission Register (ER) Goal: Locate important differences and similarities between the two datasets Non-specified sources? Availability of other methods? Possible improvements?

4. 10 May 2010EMEP/EEA Guidebook and the Netherlands Emission Register4 Netherlands Emission Register (ER) Used dataset: Emission data from the submission of the Netherlands under the LRTAP convention, for the year 2005 (as submitted in 2008) All submitted substances: SOx, NOx, CO, NMVOC, NH3, heavy metals, particulate matter, PAHs and POPs

5. 10 May 2010EMEP/EEA Guidebook and the Netherlands Emission Register5 EMEP/EEA Guidebook (GB) Guidebook Tier 1 and Tier 2 methodologies and emission factors for every relevant emission source: Emission = Emission factor * Activity rate Necessary activity data: Combustion: IEA energy statistics Other emissions: publicly available information, such as: National information sources: Statistics Netherlands, facility information International information sources: USGS, UN statistics Some (small) emission sources are not included due to lack of activity data. All important sources are included.

7. 10 May 2010EMEP/EEA Guidebook and the Netherlands Emission Register7 Some interesting differences and similarities Detailed comparison and comparison on aggregated level Example: NOx emissions Differences in use of Tier 1 and Tier 2 method Example: SOx emissions Non-specified sources Example: copper emissions Emissions of particulate matter (PM10)

14. 10 May 2010EMEP/EEA Guidebook and the Netherlands Emission Register14 Conclusion and discussion For national emission inventories, this is a simple way to check If important emission sources are missing, If the national emission estimates are different from the international standard, If either simpler or more accurate methods for estimating emissions are available Discussion Non-specified sources in the EMEP/EEA Guidebook Tier 1 emission factors
