CAD Trust announced that the Kingdom of Bhutan has fully integrated with the CAD Trust data layer. This is the first national registry to do so. CAD Trust holds Bhutan's registration data log, and the metadata layer is designed to store carbon data from multiple carbon registries. By creating a single source of truth on a decentralized blockchain, it helps prevent duplicate calculations of carbon credits. CAD Trust was jointly established by the World Bank, the International Emissions Trading Association (IETA), and the Singapore government and was launched at the end of last year.
