1. REVIEW, IMPROVEMENT & HARMONIZATION AIR EMISSION INVENTORIES NORDIC
OF THE
NORDIC
AIR EMISSION
INVENTORIES
BY COOPERATION IN
THE NAEEG GROUP

2. THE NAEEG COOPERATION IS ABOUT…
… sharing knowledge & resources to improve
ACCURACY Comparison of methods & EFs
Similar
• climatic conditions
• legal framework
• industry structure/technique
• source patterns (e.g. NMVOCs& small combustion)
COMPLETENESS   Review for “missing sources“
TRANSPARENCY   Development of NIRs
COMPARABILITY  Improved transparency, completeness,
accuracy (& consistency)
REVIEW, IMPROVEMENT & HARMONIZATION OF THE NORDIC AIR EMISSION INVENTORIES

3. WHAT IS BEHIND THE FIGURES?
METHODS…
SYSTEMATIC REVIEW
Identification of major differences in 2004 submissions
Comparing CLRTAP submissions for verification
WHAT IS BEHIND THE FIGURES?
Residential combustion (NMVOCs, POPs, PMs)
Transport (HMs, PAH)
Solvent and other product use (NMVOCs)
Pulp and paper (NMVOCs, HMs, POPs)
ANALYSIS OF THE RESULTS
Actual differences or need for inventory improvement?
Emission factors/activity data underestimated?
Missing sources or missing methodology?
Other problems?
REVIEW, IMPROVEMENT & HARMONIZATION OF THE NORDIC AIR EMISSION INVENTORIES

4. RESOURCES 2004-5 One coordinator per country
Preparation of material and analysis can be shared in the countries between experts and institutes as appropriate (explointing the best expertice)
Two annual meetings to review the results
Funding from the Nordic Council of Ministers covers
Travel costs 2 meetings/a/1 expert/country
0 - 1 month resources/country for work
Publication of Final Report
REVIEW, IMPROVEMENT & HARMONIZATION OF THE NORDIC AIR EMISSION INVENTORIES

5. WORK PROGRAMME 2004 Identification of common concerns
Data collection and analysis
Documentation
Improvement to submissions to the CLRTAP
”Nordic methodology” for cases where possible
Identification of other areas for cooperation
Dissemination of results
- Final Report and Workshop
- Feedback to the TFEIP & Guidebook
Indirect benefit to UNFCCC & EPER/PRTRs
REVIEW, IMPROVEMENT & HARMONIZATION OF THE NORDIC AIR EMISSION INVENTORIES

6. There are differences and need for harmonization
EXPERIENCES THUS FAR
STRENGTHS
possibility to actually sit down, review and discuss
learning to know your colleague makes it easy to consult
WEAKNESSES
limited resources do not allow to dig as deep as we would want to (no profound studies)
We are in the very beginning BUT
There are differences and need for harmonization
Learning from each others
