Considers the sustainability of the modern US corporation: can the corporation meet current social needs while enabling future generations to meet theirs? We begin by looking at the corporation's current and unsustainable design: its externalization of costs, its short-term focus, its groupthink decision-making, and its political personhood. We then consider recent (and remarkable) triple-bottom-line responses to this design: environmental stewardship (planet), voluntary CSR (people), and socially responsible investing (profits). We conclude by exploring some potential paradigm shifts: new social enterprise forms, new environmental/social reporting, and the corporation as a moral system.
