There is a growing scientific debate regarding the suitability of certain modes of governance for promoting sustainable development (SD). However, thus far there is neither agreement on ways to meaningfully distinguish and understand governance modes nor a foundation of the aspects to be chosen for this endeavour. In order to overcome this conceptual vagueness, this paper presents a meta-framework for a sound conceptualization of governance modes. Founded on a reinterpretation of the discourse ‘from government to governance’, we argue that only a multi-dimensional approach giving consideration to political processes (politics), institutional structures (polity) and policy content (policy) adequately captures the complexity of governance phenomena. We furthermore highlight possible key features for exploring these dimensions and compare three recently published frameworks for modes of governance. By offering a sound conceptual clarification of governance modes, we facilitate both their meaningful differentiation and a more systematic understanding of their inherent complexity. In so doing, we inform both theoretical and empirical research on governance for SD. We pave the way not only for making more differentiated theoretical statements on the relationship between governance modes and SD but also for empirically exploring this relationship on a profound basis.
