Carbon Markets Infrastructure (CMI) Working Group
Paving the way for a more safe, efficient, and interoperable carbon market infrastructure

What is the CMI WG?
Building robust and interoperable carbon market infrastructure is critical for ensuring market integrity and scalability. At COP28, the World Bank released an engagement roadmap towards rebuilding trustworthy and transparent carbon markets to have a tangible impact towards addressing the global climate crisis. This roadmap “High Integrity, High Impact: The World Bank Engagement Roadmap for Carbon Markets” recognized that the key enabler for this was reinstating trust in the carbon markets.
An integral part of reinstating and strengthening trust in carbon markets is through harmonizing and standardizing functionalities and entities across the carbon markets ecosystem. This would entail agreeing upon minimum service standards, common frameworks, and governance across the ecosystem of key players and entities such as principles-setters, independent standards, registries, validation and verification bodies, and rating agencies. This in turn requires entails working with all relevant stakeholders to unlock the most critical bottlenecks in global architecture and support development countries to build market infrastructure, institutions, and policy.
In this context, the World Bank set up the Carbon Market Infrastructure (CMI) Working Group including a wide range of stakeholders ranging from policymakers, exchanges, regulators, standard setters, and other infrastructure providers across the value chain (see the current list of participants in the bottom of the page).

The Carbon Markets Infrastructure Working Group (CMI WG), convened by the World Bank as a follow-up to the Engagement Roadmap for Carbon Markets, brought together over 45 entities to strengthen global infrastructure for high-integrity carbon markets. Through five targeted Technical Guidance Notes, the CMI WG offered recommendations to countries and market actors on addressing key challenges related to ecosystem governance, transaction integrity, information security, data interoperability, and digital MRV. By delivering practical tools, shared standards, and actionable guidance, the initiative aimed to enhance trust, scalability, and transparency across carbon market systems.
