Legitimacy and the extraordinary growth of ESG measures and metrics in the global investment management industry

ESG metrics are increasingly important in the global investment management industry. Why this came to pass given the limited appetite for responsible investing in the industry is the subject of this paper. Although the business case for ESG provides an explanation for its increasing uptake whereby market actors are increasingly convinced of the merits of ESG as a profit centre, this explanation is insufficient. By contrast, the adoption the ESG programme offers a means of rewriting the terms of risk management and value creation that while grounded in the business case also serve to address challenges to the legitimacy of the global asset management industry. These developments are illustrated in a case study of the establishment and growth of TruCost and its purchase by S&P Global in 2016.
