Present patterns of production and consumption are not sustainable. Therefore deliberate action for sustainability demands a focus on the transition of societies’ socio-technical systems. This implies a new perspective for sustainable planning and policies as it becomes a question of addressing the governance structures of socio-technical systems, understanding how such governance structures develop and shape technological development. It demands metagovernance, which is the ability and strategies to influence and shape such governance structures. This involves the question of how to stimulate reflexive processes in actor networks in existing or developing socio-technical systems in order to integrate the concept of sustainability as a driver for transition.
