This course introduces students to ESG investing and sustainability reporting. It is an exercise to bridge the gap in traditional financial reporting and fundamental analysis, and to provide a new view on how a firm's social and environmental performance are related to firm value. Through cases, interactions with guest speakers, and a group research project, students will learn about how firms communicate ESG information, how data vendors and analysts analyze ESG information to build sustainability-related metrics, how investors use them to make portfolio decisions, and most importantly, how to overcome some of the associated challenges.
