A well-structured and high-integrity carbon market has the potential to mobilize essential financing for climate action, especially in developing countries. Achieving scale will require secure, efficient, and interoperable infrastructure that fosters the growth and reliability of these markets. This "Roadmap for a Safe, Efficient, and Interoperable Carbon Market Infrastructure 2024" outlines critical bottlenecks and priority action areas identified by the Carbon Market Infrastructure Working Group (CMI WG). This includes clarifying ecosystem governance, documenting current standards and market practices related to information security and transaction integrity, and enhancing data and systems interoperability.
