Michele Betsill is professor and chair of the Political Science Department at Colorado State University, United States, where she teaches courses in international relations and environmental politics. Her research analyses global environmental governance, with a particular interest in the role of non-state actors in creating new mechanisms for steering society towards a more sustainable future. Although most of her work has focused on climate change, recent projects address issues related to natural resource extraction and marine conservation. Betsill’s publications include Transnational Climate Change Governance (with members of the Leverhulme Network on Transnational Climate Governance, Cambridge 2014); Advances in International Environmental Politics (co-edited with Kathryn Hochstetler and Dimitris Stevis, Palgrave Macmillan 2014); NGO Diplomacy: The Influence of Non-governmental Organizations in International Environmental Negotiations (co-edited with Elisabeth Corell, MIT Press 2008). Betsill is a founding member of the Earth System Governance Project and a member of its Scientific Steering Committee since 2009. At present, she is leading the Project’s harvesting initiative on the research domain of “Agency”.
