Introduction to the special issue: reform or revolution? What is at stake in democratic sustainability transformations

In the face of multiple crises of ecology, economy, and social equity, the question of how to democratically transform toward a more sustainable society is high on the political agenda as well as pertinent to academic research. The first part of this introductory article to the special issue provides a brief overview of contemporary interrelated debates on sustainability, democracy, and transformation. It discusses the main concepts, themes, and questions that are part of the highly diverse and constantly evolving body of literature on the topic, as well as differences regarding analytical frames and normative underpinnings. The overview shows that the literature remains largely silent about supporting theories of change, ontologies, methodologies, and principles—and/or the ways in which transformation, sustainability, and democracy are interrelated. The second part of this article introduces the contributions to this special issue. The special issue is guided by three overarching questions: what can we say about the possibilities and problems of democratically enacting changes toward greater social, ecological, economic, and political sustainability in societies? Which analytic frames are useful for evaluating change, including its democratic and sustainability quality? Where do evaluations and judgments derive their analytical and normative legitimacy from?
