It does not ineluctably follow from the fact that an investment promotes ESG factors, or that it arguably promotes positive general market trends or industry growth, that the investment is a prudent choice for retirement or other investors. Rather, ERISA fiduciaries must always put first the economic interests of the plan in providing retirement benefits. A fiduciary’s evaluation of the economics of an investment should be focused on financial factors that have a material effect on the return and risk of an investment based on appropriate investment horizons consistent with the plan’s articulated funding and investment objectives.As for 401(k) plans, the bulletin leaves open the option to include an ESG fund among the options: "a prudently selected, well managed, and properly diversified ESG-themed investment alternative could be added to the available investment options on a 401(k) plan platform without requiring the plan to remove or forgo adding other non-ESG-themed investment options to the platform."
