How uncertainties are handled in LCA – focus on the wastewater and textile sectors

• Life cycle assessment (LCA) relies on large data samples and includes numerous choices and assumptions. This study aimed at reviewing to what extent relevant uncertainties are communicated and considered when interpreting LCA results, looking at current practices in LCAs on wastewater and textile systems. Our review showed that uncertainties are seldom communicated or considered in relation to the conclusions of the study, despite the availability of methods for propagating uncertainties in LCAs. We discuss that uncertainties and variation should at least be qualitatively assessed, and ideally be propagated from the life cycle inventory through the impact assessment.
