The governance of corporate sustainability has changed dramatically around the world. There has been a shift from a focus on sustainability as voluntary (beyond legal compliance), social and environmental initiatives adopted by private actors to fill a governance void to a focus on government mandatory requirements. Furthermore, the regulatory focus has shifted from a domestic to an international emphasis, with companies, for example, seeking to monitor and improve labor and human rights in global supply chain factories. The chapter discusses regulatory approaches and highlights differences between hard and soft law approaches. It focuses on new tensions that have emerged as a result of government sustainability governance requirements. The chapter highlights three types of tensions: 1) between different government approaches; 2) between governments issuing regulations and the firms that are being regulated; 3) social tensions in China that the government seeks to address through sustainability regulation.
