What is ESG anyway?
“Socially responsible investing” in its current incarnation, selecting or deleting portfolio companies based on ethical criteria, dates back decades. Pension investors and others seeking to avoid industries regarded as morally questionable, such as gun or tobacco manufacturers, constituted a distinct market niche both for asset managers and data providers who compiled information to assess potential investments. In 1991 Kinder, Lydenberg, Domini Inc. (KLD) began publishing systematic annual data on roughly 650 listed corporations across several dimensions of social responsibility. Amy Domini, a principal in KLD, launched an associated index fund, the Domini 400, consisting of corporations meeting high standards for social and environmental responsibility according to KLD data. This might be seen as the birth of the contemporary ESG industry.Â
As responsible investing gained traction in the market, a gaggle of competing vendors arose to provide ESG metrics. MSCI ESG Metrics, Bloomberg, Institutional Shareholder Services, and others offered distinct cocktails that emphasized different dimensions. Not surprisingly, companies can receive different evaluations depending on who’s doing the evaluating. The Wall Street Journal reported that the ratings of three leading providers, MSCI, Sustainalytics, and Refinitive, provided surprisingly divergent evaluations yielding different market performance.Â
The confusion around ESG is built into its definition. It is not entirely clear why E, S and G belong together. Environmental metrics assess a company’s use of resources, carbon emissions, and other contributions to the natural environment. Social metrics range from the treatment of employees and human rights issues in supply chains to corporate political activism. Governance metrics evaluate how well the corporation is configured to serve investor interests (or possibly “stakeholder interests”), as well as questions such as the diversity of directors. Â
In recent years the World Economic Forum worked with the Big Four accounting firms (Deloitte, EY, KPMG, and PwC) “to identify a set of universal material ESG metrics and recommend disclosures that could be reflected in the mainstream annual reports of companies on a consistent basis across industry sectors and countries. The metrics should be capable of verification and assurance, to enhance transparency and alignment among corporations, investors and all stakeholders.” The advantages of these measures are their clarity and accessibility.Â
