Table 3 DQRs of the exemplary dataset, under the different databases

From: Method applied to the background analysis of energy data to be considered for the European Reference Life Cycle Database (ELCD)

Dataset Database DQI Score Short justification of DQI DQR
Electricity From nuclear power (FR) ELCD TeR 1 Modelled as the French technology mix 1.83
GR 2 Some activities of milling and reprocessing refers to US data
TiR 3 Some references are 20 years older than the ref. year (2009)
C 1 100% of impact categories and 100% of reference flows covered
P 2 Relevant flows measured, other flows taken from literature
M 2 EoL of intermediate activities is missing
Ecoinvent TeR 2 Some data extrapolated from Swiss power plants 1.67
GR 2 Infrastructure data from Swiss plants, only 1 uranium supplier
TiR 2 Ref. year 2002, relevant data are more updated than ELCD
C 1 100% of impact categories and 100% of reference flows covered
P 2 Relevant flows measured, other flows taken from literature
M 1 EoL and allocation also for sub-processes
GEMIS TeR 2 Referred to French representative plants but not as a mix 3.08
GR 4 Only the modeling of enrichment is correct
TiR 2-3 (depending on plant) literature comes from 5–15 years before
C 2 75% of impact categories, 90% of flows covered
P 4 Literature data and auto-estimated data
