“The Cultural Evolution of Sustainability Transitions: Exploring Narratives and Worldviews among Change Agents (CULEST)” is a research project at the University of Hohenheim, which is funded by the German Research Foundation (DFG) (since June 2025). CULEST conceptually and empirically investigates the connections between worldviews, narratives, and cultural evolution in the context of sustainability. The empirical part of the research focuses on various change agents from civil society, religion, politics, and business. Through a novel combination of worldview research and the collection and analysis of micro-narratives, the CULEST researchers aim at reconstructing the patterns of interpretation that may promote or limit social and sustainability-related change processes, or even lead to new, potentially conflictual dynamics.
