This literature review focuses on institutional investors, which have grown in importance such that they have now become the largest holders of shares in public companies globally. Historically, institutional investors tended to concentrate their ESG efforts mostly on corporate governance (the “G” in ESG). These efforts included seeking to eliminate provisions that restrict shareholder rights and enhance managerial power, such as staggered boards, supermajority rules, golden parachutes, and poison pills.

In addition, this review of ESG literature determines the following:

• There is no consensus on the exact list of ESG issues and their materiality.
• The ESG issue that gets the most attention from institutional investors is climate change, in particular their portfolio companies’ exposure to carbon risk and “stranded assets.”
• Investors should be positioning themselves for increased regulation, with the regulatory agenda being more ambitious in the European Union than in the United States.

Readers might come away from this survey skeptical about the potential for ESG investing to affect positive change. I prefer to characterize the current state of the literature as having a “healthy dose of skepticism,” with much more remaining to be explored. Here, I hope the reader comes away with a call to action. For the industry practitioner, I believe that the investment industry should strive to achieve positive societal goals. CFA Institute provides an exemplary case in its Future of Finance series. For the academic community, I suggest we ramp up research aimed at tackling some of the open questions around the pressing societal goals of ESG investing. I am optimistic that practitioners and academics will identify meaningful ways to better harness the power of global financial markets for addressing the pressing ESG issues facing our society.
