The 2015 Paris Agreement is often depicted as a turning point for global climate governance. Following years of diplomatic gridlock, it laid the foundations for a new global climate regime that invites states to partner with nonstate actors in the transition to the low-carbon society. This article critically examines the political rationalities that inform the pluralization of climate politics after Paris and the turn toward cooperative modes of governing. Drawing on an analysis of initiatives led by the United Nations Framework Convention on Climate Change that were launched to engage nonstate actors in the evolving Paris regime, we identify a global governmentality that mobilizes nonstate actors as active and responsible partners in the quest for rapid and deep decarbonization. In its search for cooperative and efficient forms of problem management, we argue, this form of rule nurtures a global space free from friction and opposition where businesses, investors, and industry are elevated as the real partners of government.
