The 6th International Conference on Life Cycle Management in Gothenburg 2013 TOWARD A STRUCTURED FUNCTIONAL UNIT DEFINITION FRAMEWORK TO LIMIT LCA RESULTS VARIABILITY

By François Cluzel, Yann Leroy and Bernard Yannou

Abstract

Functional Unit (FU) ensures the consideration of comparable product quantities to provide reliable Life Cycle Assessment (LCA) results. Although the definition of this FU is essential, it receives only a few attention in the normative texts. A high part of subjectivity is let to the LCA practitioner. In this paper variability sources of the FU definition are identified to propose a more structured and adapted approach. Literature references and data collected among 8 LCA experts on 5 case studies allow us to draw first recommendations towards a more structured FU definition framework
