The background of this conceptual paper constitutes the manifold efforts in Germany to establish and continue to develop municipal ESD landscapes. Related research is directed toward identifying factors which are either favorable or unfavorable for ESD implementation. Against this background, we outline the process of deriving research questions for new qualitative research. This is realized by adopting a governance analytical perspective. On the basis of a literature review, we elaborate on the state of research and discuss two promising governance approaches, along with associated empirical findings. Along with a further literature review, we also address why we consider expert interviews to be an appropriate approach for data collection and analysis. We conclude that it is important to not only focus on the coordination of collaborations, but also include the history of municipal cooperation, existing ESD (self-)understanding of involved actors, and collaboration practices. On this basis, we identify research gaps and specify research questions, which can serve as a basis for further research on ESD. Corresponding empirical research may optimize municipal ESD implementation processes.
