Use of Models and Facility-Level Data in Greenhouse Gas Inventories 5.1.3 Extent of use of ETS data in the EU inventory Based on the information submitted in the national inventory reports (NIRs) in 2010 to the UNFCCC secretariat or the European Commission, 24 out of 27 Member States indicated that they used ETS data at least for QA/QC purposes (see Table 5-1). This is a higher share of Member States than in 2008, where a similar analysis showed that 22 Member States had used ETS data for inventory purposes. 14 Member States indicated to directly use the verified emissions reported by installations under the ETS. 15 Member States used ETS data to improve country-specific emission factors. 10 Member States reported that they used activity data (e.g. fuel use) provided under the ETS in the national inventory. The NIR of Lithuania did not provide any information whether ETS data was used for inventory purposes. For these Member States it is unclear whether they checked data consistency in a systematic way. Luxembourg and Bulgaria did not provide an updated NIR 2009 during the preparation of the 2010 NIR. The analysis did not report explicitly whether countries has been able to discriminate between combustion and process related emissions from industry where both types of emissions occur, such as the iron and steel sector.

Use of Models and Facility-Level Data in Greenhouse Gas Inventories Source: NIR submissions to UNFCCC 2009 Figure 5-1 shows the extent of ETS use in the EU. Green indicates the NIR provides information how ETS data was used for GHG inventory. Red indicates no information provided in NIR about whether ETS data was used. No NIR for Luxembourg was available during the preparation of EU 2010 NIR. Figure 5-1 Use of ETS data for inventory purposes in the EU The following assessment provides a detailed overview of the use of ETS data in the EU-15 Member States. The information is mainly based on the NIR, as well as on the assessment conducted for this report. 5.1.4 Use of ETS data for GHG inventories in specific countries Three countries have been chosen to illustrate the use of ETS data in national GHG inventories: the two largest GHG emitters in Europe (Germany and France, with well developed national inventory systems), and Greece representing a less mature but developing GHG inventory. The authors of he EU NIR split the analysis into the use of energy, and industrial processes and the analysis they made is reproduced below. Germany General The coverage of CO 2 emissions from ETS activities in relation to individual CRF source categories is not provided in the NIR. In 2006 a research project compared ETS emissions and inventory emissions and developed allocation rules how the ETS emissions should be allocated to inventory categories. Then a formalized procedure was developed for the annual data exchange between ETS authority and the inventory system. ETS data are generally used for verification and QA purposes but not directly in the inventory. Emission factors from ETS data are also used. Activity data from ETS data are not used because these data are confidential and would decrease the transparency of the GHG inventory. In the CRF table 1s1 (Energy) Germany reports an additional source category that includes the combustion emissions from source categories covered by the ETS (glass, cement and ceramics). This additional voluntary reporting considerably enhances the comparability of ETS emissions with inventory emissions at sectoral level. Energy The NIR generally indicates that ETS data are used for verification purposes. Both systems, the inventory and the ETS, refer to a list of “basic” CO 2 emission factors in the energy sector. Industrial processes • 2A1 Cement Production: EFs between inventory and ETS are largely consistent, deviation of 1%. IPCC Expert Meeting Report 91 TFI
