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
