• Research

  

  The research group TRANSSUSTAIN is funded by the Ministry of Culture and Science of the State of North Rhine-Westphalia. Voluntary Sustainability Standards (VSS) have evolved into key transnational governance instruments to bind international markets to fundamental principles of sustainable development. As they continue to extend their influence in international markets, it is of increasing academic and public interest to study the effectiveness of VSS. TRANSSUSTAIN focuses on the effectiveness of VSS in global coffee value chains. The main research question is to what extent VSS are capable of turning global coffee production into a more sustainable industry. The group combines comparative institutional analyses of different VSS with on-the-ground impact studies in different Latin American countries. The group is based at the University of Muenster and INCAE Business School in Costa Rica.

  STRIVE is a research project funded by the German Federal Ministry of Education and Research. It aims at improving the knowledge base for the design of sustainable bioeconomy policies and regulatory frameworks at national and international level. The project focuses on the sustainability implications of transnational biomass trade, technological innovation, and innovation transfer in selected bioeconomy sectors with an emphasis on major biomass and knowledge producing countries and regions. Impacts of bio-based transformations will be evaluated against relevant sustainability dimensions, such as the Sustainable Development Goals (SDG) on poverty eradication (1), food security (2), reduced inequality (10), responsible consumption (12), climate action (13), and terrestrial ecosystems (15). We have adopted an interdisciplinary research approach integrating economics with natural and political science and rely on methods such as, economic modelling, statistical and econometric analysis, life-cycle assessment, technology & innovation management, and qualitative as well as quantitative case studies.

  Research Project: International investor-state arbitration and public policy

  This research project is self-funded. Today, investor-state dispute resolution before private arbitration tribunals is negotiated and expanded in a series of bi- and multilateral free-trade agreements such as TTIP, TPP, and CETA. Thus not only emerging and developing countries but also highly developed countries are increasingly subject to an extra-legal system evolving beyond the nation state. This development is widely associated with an over-empowerment of international investors as well as undemocratic reductions of sovereign national policy spaces. However, until now these claims have not been subjected to comprehensive empirical research. Through a series of comparative studies this project aims to better understand how the rise of international investment law and investor-state arbitration affects politics and law-making de facto in highly developed countries.
