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 CO2 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

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)

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

Specific issues to be explored…
Consistency:
of CO2 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

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

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!
