1. Quality aspects of EPER
5th Joint UNECE Task Force & EIONET Workshop on Emission Inventories and Projections, 19 October 2004
Quality aspects of

2. EPER European Pollutant Emission Register

3. EPER EPER is based on Art. 15(3) of IPPC-Directive (1996)
...and a Commission Decision (2000) on
the implementation of EPER

Internet launch on 23 Feb (EPER 1)

9. EPER Guidance Document
“The quality of the reported data is the integral result of the seven following aspects:
timeliness, completeness,uncertainty,
comparability, consistency, transparency
and the emission determination metho-
dology (M, C and E).”

10. EPER Guidance Document
Class M (“measuring”)
emission data are based on measurements using standardised or accepted methods; often additional calculations are needed to convert the results of the measurements into annual emission data

11. EPER Guidance Document
Class C (“calculate”)
emission data are based on calculations using nationally or internationally accepted estimation methods and emission factors, which are representative for the industrial sector

12. EPER Guidance Document
Class E (“estimate”)
emission data are based on non-standardised estimations derived from best assumptions or expert guesses

13. EPER Guidance Document (5)…
8. Reference to available emission
determination methods
Atmospheric Emission Inventory Guidebook,
IPCC Guidelines, EEA, US-EPA, UK, Australia, OECD, OSPARCOM, IPPC-BREF documents
...

14. EPER, review report + All MS have reported
+ Electronic validation tools are useful
+ EPER data cover often high shares of emissions
+ Additional meta-information increases usefulness
+ High interest of the public
- Not all countries sub-
mitted complete data
- Gaps for landfills, pig and poultry, metal surface treatment and some pollutants
- QA/QC procedures have to be improved (harmo-
nised methodologies)
- Translation of website ?

15. More guidance for the facilities (bottom-up approach!!) on
What to improve ???
More guidance for the facilities (bottom-up approach!!) on
Which pollutants are relevant (upgraded sector specific pollutant lists)?
Which standard method for a selected pollutant?
How to find and use international guidelines, as e.g. IPCC Guidelines

16. EPER Support documents !...done under EPER
1. Diffuse air emissions from landfills (CH4, CO2)
2. Air emissions from pig and poultry farms (NH3, N2O, CH4, PM10)
