Collective Action for Sustainability

The Department of Collective Action for Sustainability, led by Prof. Ulf Hahnel, investigates human judgment, decision-making, and the underlying psychological mechanisms in the context of climate change and the energy transition. Based on a growing understanding of sustainable decision-making, the team develops evidence-based interventions to promote sustainable behavior worldwide.

Our research is grounded in the theory and experimental methodology of psychological research and behavioral economics. Given the global and dynamic nature of climate change, we collect experimental data across Western and non-Western nations and across time. We collaborate with various academic disciplines, policymakers, and societal stakeholders to address the multidimensional complexity of climate change and translate our research into practice.

Leveraging research from the psychological sciences and behavioral economics to provide evidence-based means to contribute to the transition towards net-zero emissions around the world.
