Testing the use of blockchain to build a meta-registry for decentralized climate markets

The Paris Agreement recognizes that Parties may engage in climate markets through decentralized, bilateral cooperative approaches to achieve their nationally determined contributions (NDCs). However, climate markets trade different units, have differences in governance rules, and operate under different technological systems. The differences in these processes constrain market integration and add to the complexity of conducting transactions. Under the Paris Agreement, which relies on a decentralized approach to markets, climate negotiators are still determining whether a centralized infrastructure, such as the International Transaction Log under the Kyoto Protocol, should continue to facilitate communication between registries. Consistent with the bottom-up ethos of the Paris Agreement, the World Bank simulated a Climate Warehouse meta-registry to demonstrate the potential of a decentralized IT approach to link registry systems. This webinar will showcase findings from the simulation as a first step towards exploring the potential of blockchain for sharing and tracking climate markets data across systems and building trust in decentralized climate markets.
