The Columbia Center on Sustainable Investment (CCSI), a joint center of Columbia Law School and Columbia Climate School at Columbia University, is the only university-based applied research center and forum dedicated to the study, practice and discussion of sustainable international investment. It develops practical approaches for governments, investors, communities, and other stakeholders to maximize the benefits of international investment for sustainable development. Applying its legal, economic, and policy expertise, CCSI addresses sustainable investment holistically, bridging investment law, natural resource management, human rights, economics, political economy, and environmental management. It works to strengthen the sustainable development potential of international investment, and to ensure that international investment is mutually beneficial for investors and the citizens of recipient countries.
