Carbon Markets Infrastructure (CMI) Working Group
The Climate Warehouse is a global platform that enables the transparent tracking and exchange of climate project data, promoting integrity in carbon markets worldwide.
Background
Building robust and interoperable carbon market infrastructure is essential for ensuring integrity and scalability. At COP28, the World Bank released an engagement roadmap outlining how to rebuild trust and transparency in carbon markets and strengthen the systems that underpin high-integrity market participation.A central element of this effort is harmonizing and standardizing core functions across the carbon market ecosystem. This includes developing minimum service standards, common frameworks, and clear governance across key entities—such as principles-setters, independent standards, registries, validation and verification bodies, and rating agencies—to support consistency and credibility in the market.
The Carbon Market Infrastructure Working Group (CMI WG), convened by the World Bank as a follow-up to the Engagement Roadmap for Carbon Markets, brings together policymakers, regulators, exchanges, standard setters, and infrastructure providers to strengthen the foundations of global carbon market infrastructure.
Information security
Data interoperability
Digital MRV (Monitoring, Reporting, and Verification)
By delivering practical tools, shared standards, and actionable guidance, the initiative aimed to enhance trust, scalability, and transparency across carbon market systems.
Five Technical Guidance NotesThe group includes over 45 organizations working to improve interoperability, efficiency, and integrity across the carbon market ecosystem. Through five Technical Guidance Notes, it has provided practical tools and recommendations on ecosystem governance, transaction integrity, information security, data interoperability, and digital MRV—helping to build trust, scalability, and transparency across carbon market systems.
