The Life Cycle Assessment (LCA) represents the most used tool to evaluate the sustainable performances of a product, process or activity. The ultimate purpose of a LCA is to have a metric to compare the impacts of life cycles of products, process and activities on the environment, the society and the economy. All existing methods for each LCA stage leave an important role to the subjectivity of the practitioner. This causes heterogeneity of the assessment that reduces the comparability of the LCA results. In this paper, the heterogeneity effects on the LCA for each stage of the assessment are discussed according to a system design perspective. This will permit to transpose the practitioners’ subjective decisions into a coherence problem between 1) the choices about the methods for each LCA stage and 2) the comparability of the resulting LCA.

Abstract
The Life Cycle Assessment (LCA) represents the most used tool to evaluate the sustainable performances of a product, process or activity. The ultimate purpose of a LCA is to have a metric to compare the impacts of life cycles of products, process and activities on the environment, the society and the economy. All existing methods for each LCA stage leave an important role to the subjectivity of the practitioner. This causes heterogeneity of the assessment that reduces the comparability of the LCA results. In this paper, the heterogeneity effects on the LCA for each stage of the assessment are discussed according to a system design perspective. This will permit to transpose the practitioners’ subjective decisions into a coherence problem between 1) the choices about the methods for each LCA stage and 2) the comparability of the resulting LCA.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
