Résumé :
|
In life cycle assessment (LCA) studies are needed ways to decide which impacts are the most severe and to express overall environmental impacts in a simple format. A number of methods to this end have been developed.This thesis investigates how such methods are used and perceived in practice. It also discusses some underlying difficulties of measuring values and attitudes for the development of these methods. It was found that LCA methodology is built on a number of assumptions that make such investigations problematic. A further development of LCA methodology and practice requires deepened insights in both these fields : how results from LCA studies are interpreted and used, and how peoples values and concerns for the environment may be investigated and included in such studies.
