In this article, we outline the multifaceted roles played by non-state actors within the United Nations Framework Convention on Climate Change and place this within the wider landscape of global climate governance. In doing so, we look at both the formation and aftermath of the 2015 Paris Agreement. We argue that the Paris Agreement cements an architecture of hybrid multilateralism that enables and constrains non-state actor participation in global climate governance. We flesh out the constitutive features of hybrid multilateralism, enumerate the multiple positions non-state actors may employ under these conditions, and contend that non-state actors will play an increasingly important role in the post-Paris era. To substantiate these claims, we assess these shifts and ask how non-state actors may affect the legitimacy, justice, and effectiveness of the Paris Agreement. © 2017 The Authors.

INTRODUCTIONT he Paris Agreement now stands at the center of efforts by the international community to address the threats associated with climatic change. Within this Agreement-built upon the United Nations Framework Convention on Climate Change (UNFCCC)-non-state actors will play an increasingly important role. The presence and prominence of non-state actors within the Paris Agreement mirrors a broader shift across the international climate governance landscape in which nongovernmental organizations (NGOs), business groups, think tanks, trade unions, private governance arrangements, transnational networks, and substate authorities assume active roles in limiting the negative effects of global warming. 1,2 This conceptualization of non-state actors includes civil society, business, research groups, and substate authorities. We prefer this expansive definition as it fits alongside the definition of nonparty stakeholders employed by the UNFCCC (see also Ref 3).In this article, we focus on how the Paris Agreement further deepens and complicates the connections between multilateralism and non-state action. It does so by creating an architecture that we call 'hybrid multilateralism' that splices together state and nonstate actors (on the usage of this term, see traits: state-led action defined and stipulated by the parties through their own nationally determined contributions (NDCs) as well as efforts by the UNFCCC to orchestrate transnational climate efforts. In both instances, non-state actors are formally and informally woven into the Paris Agreement performing a range of different and increasingly important functions. Non-state actors will act as watchdogs of the NDCs enhancing transparency, facilitating the stocktakes, and pressuring for the ratcheting up of NDCs every 5 years. Likewise non-state actors will act as contributors and governing partners through orchestration as they are encouraged by the Agreement 'to scale up their climate actions, and [register] those actions in the Non-State A...
