Table 4 Matrix for assessing LCI of fuel datasets

From: Background qualitative analysis of the European Reference Life Cycle Database (ELCD) energy datasets – part I: fuel datasets

Quality indicator Subquality parameters Rating
1 (Very Good) 2 (Good) 3 (Fair) 4 (Poor) 5 (Very Poor)
TeR Expert judgement based on the consideration of a technology mix Technology aspects have been modelled as the technology mix Technology aspects are very similar to the technology mix Technology aspects are similar to the technology mix Technology aspects are different to the technology mix Technology aspects are completely different to the technology mix, or tech not deployed
GR Expert judgement based on the geographical coverage of data Involved countries fulfil completely the share of listed as referenced countries Involved countries fulfil very similarly the share of listed as referenced countries Involved countries fulfil similarly the share of listed as referenced countries Involved countries fulfil differently the share of listed as referenced countries Involved countries fulfil completely different the share of listed as referenced countries
TiR Expert judgement based on defined time on data inventory (± 5 years) All the data sources refer to the defined time The majority of the data sources refer to the defined time At least half of the data sources refer to the defined time Less than half of the data sources refer to the defined time None the data sources refer to the defined time
C Consideration of impact categories and share of elementary flows (to adjust the final rating) 15-16 considered impact categories 12-14 considered impact categories 8-11 considered impact categories 5-7 considered impact categories ≤5 considered impact categories
P Expert judgement based on the precision/uncertainty of data sources Very low uncertainty and/or very high precision Low uncertainty and/or high precision Fair uncertainty and/or fair precision High uncertainty and/or low precision Very high uncertainty and/or very low precision
M Definition of situation context and subsequent expert judgement of system boundaries, multi-functionality and EoL Inclusion of all LCA stages (with the EoL stage). Consideration of allocation procedures. Completion in a very high degree Inclusion of most relevant LCA stages. Consideration of allocation procedures. Completion in a high degree Inclusion of a still sufficient LCA stages. Consideration of allocation procedures. Completion in a sufficient degree Inclusion of a sufficient LCA stages. Consideration of allocation procedures. Completion in a low degree No inclusion of sufficient LCA stages. No consideration of allocation procedures (multi-functionality has not been solved according to the situation context). Completion in a low degree
