The Institute for Polymer Testing and Polymer Science of the University of Stuttgart has been investigating automotive parts, structures and cars during their life cycle in plenty cooperation with the European automobile producers and their suppliers for the last 9 years. Therefore a holistic approach has been developed to combine tasks from technique, economic and environment in a methodology called Life Cycle Engineering (LCE). The goal is to find a way to support designer and engineers as well as police makers and public with this three-dimensional interrelated information to have the possibility to manufacture future products in a more sustainable way without loosing contact two the traditional parameters technique and costs.

Life cycle assessment offers a suitable methodology to evaluate environmental impacts over the total life cycle of the car. Indeed the effort for LCA studies of complex products like cars is very high. Design for environment tools can help to reduce the effort for environmental evaluation because of their direct integration in the designers workflow. As DFE is not standardized, it should be based on the reliable data from LCA. A connection between LCA and DFE offers the possibility to integrate environmental evaluation with tolerable effort directly in the design process while keeping the transparency and reliability of LCA.
