This report evaluates options for how countries that are parties to the Paris Agreement can cooperate to accelerate the implementation of REDD+. The five presented options, summarized below, are not mutually exclusive and can be combined to deliver a blended flow of finance in support of the implementation of REDD+ strategies. Essential for the decision on how to combine various mechanisms and modalities of cooperation is a decision on the side of the tropical forest countries on whether and how much emission reductions they wish to transfer in return for financial support and how such transfers will affect their ability to achieve their nationally determined contributions (NDCs).
