Although waste prevention was promoted as the first priority for all EU member states in 2008, the actual implementation of activities has thus far been hesitant. Empirical evidence indicates that the reasons for this neglect include the limited measurability of waste prevention effects and the consequential lack of awareness, motivation, and incentive systems. Our research aims to quantify waste prevention and its environmental impacts and, ultimately, to motivate the efficient implementation of waste prevention concepts by a target-group-specific communication of the results.Embedded in a transdisciplinary research setting in close cooperation with practitioners, we develop a life cycle-based approach to calculate the effects of waste prevention in local authorities. This approach features an activity-based analysis that facilitates the assessment of both reduction of waste generated and the related environmental effects. The methodology of life cycle assessment, used to calculate environmental impacts, is adapted to the specific requirements and constitutes an essential step in our measurement approach.Finally, we demonstrate the application of this approach. Five activities deriving from realworld case studies are assessed. These case studies simulate the implementation of waste prevention in a mid-sized German city. We are able to reveal potential waste reduction of 74% and potential reduction of other environmental impacts ranging from 28% to 62% of the targeted material streams.
