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?

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

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.

Comparison

• Comparison for aggregated categories to show the big picture

• Also for reducing allocation differences

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)

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
