Dialogues on climate issues, including the various multilateral agreements, have largely been driven by traditional state-to-state diplomacy. Nevertheless, over the years, new diplomatic players, such as cities, public institutions, and other subnational entities, are gaining significant importance in climate diplomacy, and have brought forward ambitious commitments. Still, the United Nations Framework Convention on Climate Change remains the domain of national entities and does not recognise subnational actors as formal parties to the convention. This policy brief aims to explore the potential for a global multilateral platform to provide a voice for subnational entities to negotiate and collaborate on climate action through the G20.
