The Columbia Center on Sustainable Investment (CCSI), a joint center of Columbia Law School and Columbia Climate School at Columbia University, 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. We envision a world in which international investment contributes to, and does not undermine, sustainable development.

We develop and disseminate practical approaches to maximize the benefits of international investment for sustainable development—and to minimize its harms—by conducting rigorous research, providing policy analysis and advisory services, offering educational programs, developing tools and resources, and fostering multi-stakeholder dialogue and knowledge-sharing.

We integrate legal, economic, and policy expertise, and approach sustainable investment holistically, bridging diverse disciplines, including investment law, natural resource management, human rights law, economics, political economy, finance, and climate change policy.  One of our great strengths lies in having knowledgeable perspective across the range of stakeholders, tools, policies, and practices that shape investment flows and outcomes. This allows us to work across communities of practice and with different stakeholder groups, and to provide insight and solutions at the intersections of these often-siloed areas relevant to sustainable investment.
