Presentation Transcript

  1. 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 (1998-2002) • 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 1990-2004 • 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 1990-2004 • 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
