Maximizing the potential of the Paris Agreement: Effective review in a hybrid regime

The hybrid model of international climate policy embodied in the Paris Agreement requires countries to regularly deliver their nationally determined contributions (NDCs) and to progressively increase collective and individual efforts over time. To be effective, this type of regime requires international review processes that provide robust information about countries’ efforts to address climate change and the support they offer other countries to do so, as well as their future plans and trajectories. The regime must also provide substantial opportunities for state and non-state actor engagement with this information, as well as sharing of best practices.
