Interests / Engagements

Trained in law, public policy and sustainable development, Professor Cordonier Segger works on the intersections of law, policy and governance related to climate change, biodiversity conservation, economic development and sustainability, with a focus on the interests of future generations and global justice. Building on her experience in treaty negotiations and implementation systems, including stakeholder consultation and engagement, her research focuses on how international law responds to global challenges on different levels. It combines doctrinal analysis and theory with empirical research and draws on law, politics, development studies and environmental management. Her present research focuses on international law on climate change; sustainable development in global and regional trade, investment and financial treaties; legal preparedness for the green economy; international legal aspects of sustainable use of biodiversity and natural resources; and questions of law, governance and inter-actional regimes.

She also serves on the boards of the International Law Association, the Sustainable Development Solutions Network of Canada; chairs the Future Board of (a purpose-led biomedical firm), the UN International Law on Sustainable Development Partnership; is a Councillor of the World Future Council, and lectures in the University of Victoria, the University of Chile and other law faculties.
