Climate Action Data Trust

The Climate Action Data Trust (formerly known as Climate Warehouse) is a global platform that links, aggregates and harmonises all carbon credit data from project registries to facilitate transparent accounting. It aims to mobilise climate action toward the Paris Agreement’s objectives by enhancing transparency and environmental integrity of carbon credit transactions and international carbon markets.

Summary Report.

Simulation I - Connecting Climate Market Systems

The Paris Agreement introduced a bottom-up approach for addressing climate change by enabling countries to pledge individual commitments through nationally determined contributions (NDCs). Furthermore, Article 6 of the Paris Agreement recognizes that Parties may engage in bilateral cooperative approaches, including through the use of internationally transferred mitigation outcomes (ITMOs), to achieve their NDCs. In the first phase, the project identified potential prerequisites and requirements of Article 6.2 and conducted a pilot simulation of a prototype to test blockchain's utility as the underpinning platform technology to connect heterogeneous registries to track units and avoid double counting issues across those registries.

Final Report

Simulation II – Connecting Climate Market Systems

The second phase of the Climate Action Data (CAD) Trust prototype development, which built on lessons learned from the simulation phase I, focused on testing the meta-data layer infrastructure with updated data fields. One of new features of the second phase prototype is the provision of an auxiliary application which mimics the minimum functions of a registry and thereby enables participation by country participants that currently do not have a registry. The second simulation involved broader participation, establishing 16 registry nodes and over 20 observer nodes.

Simulation III – Connecting Climate Market Systems

The third phase of the Climate Action Data trust prototype development, which builds on the lessons learned and findings from Simulation II, aimed to test CAD trust on an open source, interoperable and permissionless public blockchain platform, and develop a minimum viable product to operationalize the CAD trust consistent with the recommendations from the 6-month consultation on the governance and financing model of the CAD trust that was completed in February 2022. The consultation was co-convened by the International Emissions Trading Association, the Government of Singapore and the World Bank.
