Head of working group Scientific Assessments, Ethics and Public Policy

Dr. Martin Kowarsch

Dr. Martin Kowarsch heads the working group Scientific Assessments, Ethics, and Public Policy. His research interests include:

  • Theory and practice of science-informed democratic deliberation about policy alternatives that integrates values & ethics. The starting point is J. Dewey's philosophy;
  • A focus is on the evaluation and design of integrated environmental assessment processes at the science-policy-society interface (e.g., GEAs, science-informed deliberative mini-publics,...);
  • Pragmatist environmental ethics; Albert Schweitzer's moral philosophy; application & policy-relevance of (climate) ethics; ethics and economics.


Currently, Dr. Martin Kowarsch is leading the science-informed citizen deliberation process in the BMBF project ARIADNE on the German energy transition (2020-23), as well as a similar process on the local level - i.e. the project "Wald Brandenburg" (2021-22) funded by DBU. Additionally, he is reponsible for a section of the FORMAS Rivet project (with Univ. Lund) on "Risk, values, and decision-making in the economics of climate change: Towards a deliberative science-policy approach to the integration of diverse values in model-based climate economics" (2020-2024).

Jointly with Ottmar Edenhofer, Dr. Martin Kowarsch developed a refined science-policy model called the “Pragmatic-Enlightened Model” (PEM). Based on Dewey’s pragmatist philosophy, it suggests to explore alternative policy pathways and their implications jointly with stakeholders in an iterative deliberation process. The PEM influenced the assessment strategy of IPCC Working Group III during the fifth assessment cycle, and guides the assessment activities at MCC. Kowarsch was coordinator of a joint research initiative (2013 - 2017) with the United Nations Environment Programme (UN Environment) called “The Future of Global Environmental Assessment Making” (FOGEAM). This interdisciplinary evaluation of past global assessment-making was intended to inform future choices in assessment design. Moreover, Kowarsch provided reviews and advice for the GEO-6 assessment by UN Environment, the EU science advice mechanism, and other science-policy interfaces. Kowarsch studied philosophy and furthermore economics, and served as Associate Editor for Palgrave Communications (2017 - 2020). He is member of the Integrated Assessment Society (TIAS).
