MCDA and LCSA—a note on the aggregation of preferences

Abstract

Cost and social dimensions are now being added to the existing environmental Life Cycle Assessment (LCA), leading to Life Cycle Sustainability Assessment (LCSA). LCSA is very complex with deep uncertainties and, generally, involves several stakeholders. Therefore, the analysis and interpretation of the outputs of LCSA is a difficult and complex task, requiring aggregation of preferences. The work in progress here presented deals with a study regarding the use of open exchange interactive software packages dedicated to Multi-criteria decision aiding in the context of LCSA output analysis and interpretation.
