Introduction
Netherlands Environmental Assessment Agency
• Evaluating policy
• NIR, Environmental Balance, Environmental data compendium
• Emission Registration (PER)
A.J. Leekstra & G.J.C. Stolwijk: PER in the Netherlands EPA conference, may 16th 2007 2
Data in the PEREmissions of 800 point sources
(IPPC facilities, Emission reports (ER’s))
1200 source categories with national totals and activity levels
Divided into 55 work packages (14 emission experts)
5 Task Forces:• Energy sector, industry, waste• Agriculture• Transport• Water• Consumers

A.J. Leekstra & G.J.C. Stolwijk: PER in the Netherlands EPA conference, may 16th 2007 6
Spatial allocation
• Geographical location (i.e. Road database, Land use map, facility locations)
• Activity level (i.e. Traffic intensity, Grassland used for cattle, amount of fuel used)

A.J. Leekstra & G.J.C. Stolwijk: PER in the Netherlands EPA conference, may 16th 2007 12
Emission Explorer
• To compare datasets in graphics or tables• To check on completeness• To analyze trends
– Hierarchical on all source levels– In emissions– In activity data
• To export data

Public website
To inform the public about emission sources in their neighborhood (and, by doing that, increasing the involvement of the public in the validation of emission data)– Bilingual (English and Dutch)– Integrated system of point sources and diffuse sources– Integrated compartments (air, soil, water indirect and direct)– Maps per emission source, 5*5 km grid, per community, water catchment
area etc.– Emission Explorer, no activity data– Methodologies used– Detailed exports

Conclusion
• Automation of our dataflow has significantly improved our data collection process
• Different user types have different needs, in creating multiple views on the same data we meet specific needs.
• Point source information can now be presented to the public
