Thomas Hahn’s research focuses on ecological and institutional economics in relation to ecosystem services, climate action, green economy, sustainability transformation, and adaptive governance of social-ecological systems

Hahn recently won a large Mistra research grant of 40 MSEK together with Stephan Barthel and 20 other researchers for the project Fair Transformation to a Fossil Free Future (FAIRTRANS).

He also leads a Formas project - Increasing legitimacy and stakeholder involvement in ecological compensation/biodiversity offsets. He is presently a lead author of the Values Assessment of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) and was CLA for the recent IPBES European and Central Asian Regional Assessment.

Hahn is assistant professor in environmental social science, specialised on ecological economics. He holds a PhD from the Swedish University of Agricultural Sciences (SLU), where he studied property rights of the indigenous Sami people, ethics, and conflict resolution. With a background in agricultural economics, his research is inter- or even transdisciplinary, collaborating with stakeholders engaged in issues from biosphere reserves to climate justice.

In 2013, Hahn worked half-time co-authoring a report, commissioned by the Swedish government, on the value of ecosystem services. He served 12 years as a board member of Sveaskog AB, the largest forest owner in Europe, and for two years as a board member of the Swedish Nuclear Waste Fund. He is a fellow of KSLA (The Royal Swedish Academy of Agriculture and Forestry) and senior advisor to the think tank Global Utmaning (Global Challenge). The latter collaboration resulted in the new Mistra research grant (40 MSEK).

He regularly gives presentations about his research to various Swedish parliamentary committees, the Swedish Environmental Protection Board, the Swedish Board of Agriculture, and decision-makers in the private sector, including NGOs.

Hahn collaborates regularly with other departments at Stockholm University on teaching and research. He served as director of studies for several years and leads a SRC MSc course called Governance and Management of Social-Ecological Systems. In 2015 Hahn’s teaching was featured by Stockholm University.
