Technical Guidance Note on Enhancing Data and Systems Interoperability for Carbon Markets: Current Landscape and Strategic Recommendations

The "Technical Guidance Note on Enhancing Data and Systems Interoperability for Carbon Markets: Current Landscape and Strategic Recommendations" is one of five guidance notes prepared by the Carbon Markets Infrastructure Working Group (CMI WG). This note aims to inform ongoing efforts to improve data interoperability across carbon market systems—enabling consistent, transparent exchange of data between registries, programs, and jurisdictions. It outlines key challenges such as data fragmentation and inconsistent reporting; offers a stocktake of global initiatives to standardize carbon credit data; and provides targeted recommendations for aligning registry systems and data practices. Designed for modular adoption, the note aims to help stakeholders enhance comparability, support Article 6 implementation, and build connected, interoperable carbon markets infrastructure.
