Addressing Complexity - The Rise of the Hybrid Multilateral Climate Regime and its Impact on the Role Played by ENGOs in the Governance of Climate Change

he spread of transnational and global phenomena is putting under strain the state-centric bias crystalized, inter alia, in inter-national law and in traditional forms of multilateralism. In this context, climate change can be considered as the transnational and global phenomenon par excellence, and for this reason it might be relevant to investigate over new forms of multilateralism enhancing the role played by NSAs and increasing the effectiveness of the global climate governance system. Accordingly, after duly addressing the literature on the issue at stake, this study has developed the concept of ‘hybrid multilateral climate regime’ (HMCR) and it has taken trace of its process of materialization with the aim of understanding to what extent does the HMCR emerging from the Paris Agreement has strengthen the role played by a particular category of NSAs (i.e., ENGOs) in the global system of climate governance.
