1. 9-10 February, EEA, Copenhagen
Danish Experiences
Workshop on data consistency between national GHG-inventories and reporting under the EU ETS
9-10 February, EEA, Copenhagen
Leif Hoffmann
National Environmental Research Institute, Denmark
Department of Policy Analysis

2. Presentation Institutional set up – GHG/ETS teams Legal background
Establishing technical basis for ETS
Examples
Final remarks

3. Organisation of work
GHG-inventories: National Environmental Research Institute (NERI)
EU ETS: Danish Energy Authority (DEA) + Danish Environmental Protection Agency (DEPA)

4. Resources NERI GHG-inventory, reporting etc.
UNECE – inventories, reporting etc.
6 man years/year
NERI: 10 persons involved in inventories – technical and database support
2 external consultants involved

5. Resources DEA
EU ETC – legal basis, administration, data collection, and reporting etc.
≈ 10 man years/year

6. Legal background Law on CO2 allowances of 9 June 2004
Law revision of 1 June 2005 regarding credits from JI and CDM projects
Notices on verification, reporting, and fees

7. Technical basis for ETS
Preparation of Danish guideline
Coordination of default EF with NERI
Standard reporting forms
Guideline for accreditation/verification

8. GHG-inv. >< EU ETS
Energy consumption: same basis for GHG-inv. and EU ETS
ETS used for identification of missing sources in GHG-inv.
ETS used for verification of top-down methodologies applied in GHG-inv.
ETS used for development/calibration of top-down estimates

9. Verification of methodology
Production of bricks
Estimation methodology has been developed based on assumptions
Estimates compared with information compiled by ETS ( )
Correlation between top-down and bottom-up

10. Verification of methodology
Consumption of lime for flue gas cleaning
Methodology has to be based on statistical information available from
EF based on stoichiometric relations
Statistics on generation of gypsum from power plants used as activity data
Verification of methodology
Same methodology applied for waste incineration

11. Calibration of methodology
Consumption of lime for refining of sugar
Methodology has to be based on statistical information available from
Statistics on production of sugar
Consumption of lime and precipitation of CO2
Assumed degree of precipitation used in estimation
Methodology calibrated

12. Final remarks
Formal agreement between NERI and DEA regarding exchange of information
New information for GHG-inv. will be available (comb. of fossil fuels)
Process information from major companies will be available – the company has to report once
Due to the legal basis DEA can get information that are not available for NERI
Confidentiality of data has to be handled
