Contribution-based prioritization of LCI database improvements: the most important unit processes in ecoinvent


Reinhard, Juergen; Wernet, Gregor; Zah, Rainer; Heijungs, Reinout; Hilty, Lorenz (2019). Contribution-based prioritization of LCI database improvements: the most important unit processes in ecoinvent. International Journal of Life Cycle Assessment, 24(10):1778-1792.

Abstract

Improving the quality and quantity of unit process datasets in Life Cycle Inventory (LCI) databases affects every LCA they are used in. However, improvements in data quality and quantity are so far rather directed by the external supply of data and situation-driven requirements instead of systematic choices guided by structural dependencies in the data. Overall, the impact of current data updates on the quality of the LCI database remains unclear and maintenance efforts might be ineffective. This article analyzes how a contribution-based prioritization approach can direct LCI update efforts to datasets of key importance.
