QUALITATIVE EVALUATION OF LIFE CYCLE ASSESSMENT STAKEHOLDERS REQUIREMENTS IN SPAIN

Abstract

Life Cycle Assessment (LCA) is a tool for the systematic evaluation of the environmental aspects of a product, process, or system through all stages of its life cycle. ISO standards describe the requirements to do a LCA study, which indicates that in defining the scope and objective of an study should clearly manifest product features. The selection of inputs and outputs, the level of aggregation within a category of data and system modeling should be consistent with the study objective. The system should be modeled so that the inputs and outputs at its boundaries are elementary flows. To do a LCA study is necessary data to analyse and calculate the impacts of some product, process or services. The dependence from stakeholders is very big, because to get all information considered by LCA expert is a laborious work and not always possible to achieve. This paper present the result of 20 interviews from LCA experts in Spain, whose goal is identify qualitatively the requirements to do a LCA study. This requirements was transformed in categories to facilitate its further assessment and validation.
