A prominent securities regulator recently observed that "ESG no longer needs to be explained." ESG is firmly ensconced in the mainstream of corporate America, a frequent topic in boardrooms, C-suites, investor meetings, and regulators' remarks. Perhaps less obvious is that ESG has yet to be mainstreamed, as it were, in internal corporate governance and operations at the individual company level. In order to be a meaningful factor in effectuating corporate purpose, ESG—or, more accurately, EESG (including Employees as well as Environmental, Social, and Governance)—must be integrated throughout corporate affairs, not just in the boardroom.
