1. 1 EUROPEAN COMMISSION CLIMATE CHANGE UNIT Data consistency between National GHG inventories and reporting under the EU ETS Dr. Erasmia Kitou Climate Change, Ozone and Energy Unit DG Environment Copenhagen, February 2006

2. 2 EUROPEAN COMMISSION CLIMATE CHANGE UNIT Facts… Under the EU ETS, emission reports due end of March for (X-1) EU ETS will generate a completely new EU-25 emissions data set on CO 2 emissions for the sectors covered by the scheme Bottom–up plant-installation based vs. top-down approaches used in the energy or industry sector Installation-level data reported by Member States to various reporting schemes should be consistent

3. 3 EUROPEAN COMMISSION CLIMATE CHANGE UNIT Imminent problems Corrections of inventory data due to detailed EU ETS data (2006 submission of the GHG national inventory) - recalculations Changes to the base-year and national GHG emission inventory for the Energy and Industrial Processes Elaboration of sector caps in the National allocation Plans for the second phase of EU ETS (2008-2012)

4. 4 EUROPEAN COMMISSION CLIMATE CHANGE UNIT Significant Consequences… Environmental integrity Comparability of units Quality of the national greenhouse gas inventories Reviews of greenhouse gas inventories under the UNFCCC and the Kyoto Protocol

5. 5 EUROPEAN COMMISSION CLIMATE CHANGE UNIT Workshop Objectives Data matching:Technical, institutional and legal problems Data consistency (short and long-term): Experiences, best practice Inventory improvement based on EU ETS Data integration QA/QC checks

6. 6 EUROPEAN COMMISSION CLIMATE CHANGE UNIT Specific issues to be explored…cont. Up-to-date use of plant-specific data (energy and industrial processes) in national GHG inventories Comparability: EU ETS data and GHG inventory data (sectors where mass balance approach) Bottom-up (EU ETS) vs. top-down (NIR) Differences in coverage, effects of thresholds in EU ETS Definitions of sources: inventories vs. EU ETS Data quality: direct use of data from EU ETS in GHG inventories

7. 7 EUROPEAN COMMISSION CLIMATE CHANGE UNIT Specific issues to be explored… Consistency: of CO 2 emission factors for fuels, available options (e.g. oxidation factors, emission factors, calorific values) with official energy statistics of time series with EU ETS data (base year estimates?) Timing: release of inventories and the EU ETS reporting period Confidentiality issue: access to EU ETS data for GHG emission inventory purposes EU monitoring guidelines vs. IPCC Guidelines for national GHG inventories

8. 8 EUROPEAN COMMISSION CLIMATE CHANGE UNIT The workshop as a basis for… amendment of: Decision 280/2004/EC of the European Parliament and of the Council concerning a mechanism for monitoring Community GHG emissions and for implementing the Kyoto Protocol (also 2005/166/EC) …and connecting to: Commission Decision 2004/156/EC establishing guidelines for the monitoring and reporting of GHG emissions

9. 9 EUROPEAN COMMISSION CLIMATE CHANGE UNIT At the end of this workshop… We need to know: Where the differences lie? How significant they are? How fast they can be addressed? We need to have identified: Current best practices Practical and efficient reporting framework Ways to ensure quality of GHG inventory Concrete steps towards future alignment of reporting requirements Future submissions need to be consistent!
