Do environment, social, and governance (ESG) criteria influence a firm's financial performance, and if so, how? What are impact investments and how should they be assessed? Sustainable finance has evolved and is now a relevant topic in the global finance agenda. This course studies this evolution from the perspective of sustainability investments and impact investments. We cover among other topics ESG criteria, multi-stakeholders' perspectives, green bonds, sustainable asset management, sustainable development goals (SDG) investments, and impact investments.
