BlackRock, State Street Corporation, The Vanguard Group, AllianceBernstein, Nuveen, and PIMCO are some of the largest U.S.-based financial managers involved in marketing and executing ESG-related investment strategies. The American Federation of Labor and Congress of Industrial Organizations (AFL-CIO) and large public sector labor unions, such as the American Federation of Teachers, also push their members who serve as trustees to have those organization investments adhere to environmental, social and governance standards. This is in sharp conflict with pension plans' duty to make fiduciary decisions in the sole interest of maximizing investment returns to ensure that all of the pension benefits promised to and earned by members will be fully funded.
