Can private governance boost public policy? Insights from public-private governance interactions in the fisheries and electricity sectors

Based on the inductive analysis of two parallel cases of private environmental governance - private, market-driven fisheries governance and private, market-driven governance for electricity decarbonization - this paper uncovers a trigger for positive public policy spillovers from private environmental governance. It identifies circumstances that prompt groups of business actors working as private regulators to also take on a role as public policy advocates and supporters, revealing a potential for private governance initiatives that are targeted at a particular environmental problem to serve as a bolster for the public regulatory governance of that problem as well. Both private governance cases at the basis of this analysis feature groups of business actors seeking to meet voluntary sustainability goals through the tools of private governance (specifically, through flexing buyer power and private authority in an effort to reform environmentally problematic practices among particular groups of suppliers). In both cases, the business's inability to attain private sustainability goals though private governance means alone has given rise to business demand for facilitative public environmental policy and regulation. The analysis presented in this paper thus points to the occurrence of a particular and intriguing pattern of complementarity between private authority and public policy - one where public policy is called on to fill gaps left by private environmental governance and authority. And it identifies key conditions for such private-governance-driven recentering of public policy to occur, namely the presence of private supply chain greening goals and commitments that are economically, reputationally, and/or competitively critical for businesses to attain, combined with shortfalls in the capacity of businesses' private authority to bring about such attainment. The two case analysis further suggests the importance of ENGOs in identifying and activating some of the opportunities for leveraging shortfalls in private environmental governance to the advantage of public environmental policy and regulation.
