The Usefulness of an Actor’s Perspective in LCA
Paper i proceeding, 2011
This paper is an argumentation for adding an actor’s perspective to lifecycle
assessment (LCA). The need for this perspective stems from a criticism
about the usefulness of LCA interpretation methods comparing the relative
contribution of life-cycle phases of a product. Our argumentation is based on four
previously published studies providing practical examples of how value chain
actors’ influence may be considered in an LCA and the benefit of doing so.
Manufacturing sector examples show how one company's influence can be
illustrated in results and how it may relate all relevant emissions to its own
processes. The food sector study shows how to assess several value chain actors’
individual improvement potential. The final example, taken from building sector,
explore how to consider the fact that actors in one part of the value chain can
influence other actors to improve.
