Despite a current lack of empirical evidence, there are numerous frameworks emerging for exploring societal transitions across levels. There is focus on pathways for sustainability transitions, which tends to look at projected, normative scenarios for the future, and explore or back-cast the institutional and societal changes that are required to get there . There is also work that looks at scaling up of smaller sustainability initiatives, through processes of scaling up, scaling out and scaling deep . In particular, systems thinking provides an organising framework for bringing together multiple disciplines and perspectives, to understand problem framings, and normative and design aspects of social systems and behaviours . Within this, Meadows  framework of leverage points for systems transformation has been operationalised within the sustainability transformations debate . Here, system properties relating to system paradigms and design are leverage points where interventions can create greatest system change; shallower leverage points relate to materials and processes. This framework is increasingly being used across a range of sustainability problems as boundary objects for cross-disciplinary, critical research .
