Abstract
In the face of existing obstacles in the interdisciplinary research on sustainable consumption behaviors, we argue for the need of an integrative framework from an interdisciplinary perspective. Such a framework is presented in the form of a three-dimensional cube model of sustainable consumption behavior (SCB-cube) extended by a fourth impact dimension. The model has two purposes for application: First, to systematize existing research on different behaviors on a common taxonomy and second, to facilitate the selection of relevant sustainable consumption behaviors in social sustainability research based on impact. We critically appraise existing intent- and impact-based research approaches on the four key dimensions of the SCB-cube, focusing on the ecological and socio-economic impacts of consumption behaviors. Recommendations for the selection of relevant behaviors for empirical behavioral research are given, using the SCB-cube as a guiding heuristic. The main audience for this model is social science researchers measuring sustainable consumer behaviors on the individual level.
