1. Use of non-Party estimates in EMEP modelling: HMs and POPs

EMEP/MSC-E

2. Requirements to emissions data for modelling
Spatially resolved data for the whole EMEP region
Temporal variation of emissions
Chemical speciation of Hg; congeners of POPs
Height of emission sources
Size distribution of emitted particles

3. Available EMEP emissions data
Completeness of reported HMs emission totals for
Complete datasets of emission totals are available for 20 countries
There is no national emissions data for 9 EMEP countries

4. Available EMEP emissions data
Completeness of reported PAHs emission totals for
Complete datasets of emission totals are available for 15 countries
There is no national emissions data for 17 EMEP countries

5. Available EMEP emissions data
Coverage of EMEP region with emission data for Pb (2004)
Coverage of EMEP region with emission data for B[a]P (2004)
Gridded data – 19 countries
Gridded data – 14 countries

6. Gaps of EMEP emissions data
Minimum reporting:
Incomplete data on emission totals
Scarce data on spatial distribution
Additional reporting:
No data on temporal variation
No data on speciation (Hg, POPs)
No data on height of emission sources
No size distribution of emitted particles

7. Non-Party emission estimates
Heavy metals (Pb, Cd, Hg)
TNO estimates for 2000, 2010 and (Denier van der Gon et al., 2005)
ESPREME project estimates for 2000, 2010
POPs (PAH, PCDD/F, HCB, PCB, HCH)
POPCYCLING-Baltic project estimates (Pacyna et al., 1999)
NILU/Lancaster University estimates (Breivik et al., 2002)

8. Non-Party emission estimates
Pb emissions in Europe according to ESPREME estimates (2000)
Pb emissions in Europe according to official data (2000)

9. Summary
Reported emission inventories for heavy metals and POPs are incomplete and of limited value in terms of model applications
Use of non-Party emission estimates allows filling gaps of official inventories and composing a complete dataset for model application
Regular, reliable and officially approved non-Party estimates are required to supplement national emission data for modelling purposes
