Collective Action for Sustainability

The Center for Psychology of Sustainability and Behavior Change led by Prof. Ulf Hahnel examines human judgment and decision-making and the underlying psychological mechanisms in the context of global climate change and the energy transition. Based on an enriched understanding of sustainable decision-making, the team develops evidence-based interventions to promote more sustainable actions around the world.

Our research is grounded in theory and experimental methodology from the psychological science and behavioral economics. In light of the global and dynamic nature of climate change, we collect experimental data across Western and non-Western nations and across time. We work with various academic disciplines, policymakers, and stakeholders to account for the multidimensional complexity of climate change and to transfer our research into practice.
