Design for Environment (DfE) or Ecodesign are methods supporting product developers in reducing the total environmental impact of a product early in the product development process. This includes reducing resource consumption as well as emissions and waste. New EU directives such as WEEE and RoHS introduce the concept of ecodesign. A sound life cycle based Ecodesign can potentailly enable to provide reliable decision support at a largely reduced effort for performing the study.
