Abstract
Sustainability as a narrative has mainstreamed, but practice is stuck in the ‘valley of death,’ with exemplary business action to internalize social and environmental externalities remaining ad hoc and small scale. Civil regulation has had significant impacts, but appears unable to act as a driver of systemic change. Addressing change at the system level requires the evolution of corporate governance away from intensive towards an extensive accountability, embedded within a ‘public fiduciary.’ Such a shift in fiduciary arrangements is needed to institutionalize and leverage the growing involvement of the state in economic and industrial practice through direct enterprise ownership, the increasing importance of sovereign wealth funds and national development banks, and the significance of public-private partnerships. This re-emergence of the role of the state in economic governance will underpin the next generation of corporate responsibility, framed largely by an international political economy led by major emerging economies.
