3. Conclusions from SG3 meeting 14.06.11
Guidance document development
first revision. December 2010  Needs further revision
Development of EI questionnaire
march 2011  Continues in order to define workshop next year
Interaction with SG4
analyze case studies according to SG4 workplan
Feedback to the guidance document for second revision (inputs from other SG?)
second revision. December 2011  Ready by September 2011

4. Conclusions from SG3 meeting Key message
Information on urban emissions and projections is essential to determine the origin of exceedances and to identify means to reduce exceedances in the future
The present top down approaches for downscaling emissions from regional to urban scale are not sustainable because they do not enable the necessary link between measures, plans and emission reductions at urban scale
At urban scale, we need bottom-up approaches!

5. Conclusions from SG3 meeting Vision
Fairmode SG3 on “Urban emissions and projections” aims to be
an open forum for exchange of expertise and information
on the bottom-up compilation of urban emissions
and the evaluation of urban control measures

6. Conclusions from SG3 meeting Main Tasks
Map current practices for compilation of urban emissions
Recommend best practices to improve emission inventories at urban level
Identify basic procedures to develop emission projections consistently with emission inventories at urban level
Identify essential data and information that needs to be made available to facilitate the use of above best practices

7. Conclusions from SG3 meeting What needs to be changed?
Impact from SG3 group needs to be extended!
New list of interested parties under elaboration
Funding for annual workshops needs to be in place
Funding for compilation of best practice guidance needs to be secured
There is a proposal to include additional co-chairs to enforce funding capabilities
Work plan for 2011 has been revised (see next slides)

8. Deliverables for 2011+
Forum to give recommendations to improve emission inventories and projections at the urban scale
Workshop reports (focused on transport; Industry; Domestic, natural and agriculture sources; QA/QC):
Current status
Recommendations on best practices to improve emission inventories at urban level
Identification of basic practices to develop emission projections consistently with emission inventories at urban level
Identification of data and information that needs to be made available to facilitate the use of these best practices

9. Workplan for the next semester +
Refine the background document (July 2011):
Include a clear vision and objectives
Incorporate future steps
Emission Inventory questionnaire implementation:
Incorporate suggestions from other SG (July 2011)
Prepare the questionnaire (September 2011)
Invite forum members to participate (October 2011)
Compile results (January 2011)
Extract conclusions on expertise mapping and recommendations for workshops (February 2011)
Workshop at the next FAIRMODE meeting

10. Questionnaire Individual questionnaire for each sector:
Transport (SNAP 7 & 8)
Residential, commercial and institutional (SNAP 2 & 6)
Industry, energy and waste management (SNAP 1, 3, 4, 5 & 9)
Agriculture/Nature (SNAP 10 & 11)
Specific multi-choice questions depending on methodological approach:
Top-down
Bottom-up
Hybrid

11. Questions for top-down method (1)
From which inventory do you downscale?
National EMEP/IIASA
regional/local non-regulatory
scientific literature
What horizontal spatial resolution do you downscale to?
< 1 km2
1 > km2 < 5
>5 km2
How do you allocate the geographical distribution of emissions
by use of geographical data (e.g. land use)
by use of ancillary data (e.g. surrogates)
other
What type of sources do you distinguish
Point Sources
Lineal Sources
Area Sources
Only gridded area sources
Are you providing vertical resolution for this sector?
YES NO
What is the temporal resolution for this sector?
Annual
Weekly
Daily
Hourly

12. Questions for top-down method (2)
If you provide finer temporal resolution than annual, which data is the basis for your estimates?
scientific literature
local emission measurem.
other local measurem.
statistics
What is the source for your emission factors?
EEA / CORINAIR
USEPA
National specific
HBEFA
Other
What is the source for your activity data?
National statistics
Regional and local statistics
Sector specific reports
