Creates free open data standards to make carbon credit information consistent across different markets.

Carbon Data Open Protocol (CDOP) is a multi-stakeholder initiative launched in 2025 to standardize carbon market data across voluntary and compliance systems. Emerging from Climate Week NYC as an open-source GitHub project, it aims to address fragmentation in carbon credit tracking by creating interoperable schemas for project attributes, credit issuance, and retirement data. Backed by 52 organizations including the World Bank's Carbon Market Infrastructure Working Group and the Climate Action Data Trust, CDOP aligns with Article 6 of the Paris Agreement.

The protocol operates as a public good with no disclosed revenue model, relying on institutional support rather than commercial sales. Its Version 1.0 schema launched in 2025 targets the $79 billion global carbon market, which faces mounting regulatory scrutiny over transparency gaps. CDOP's technical working groups include registry operators, auditors, and corporate buyers seeking to reduce due diligence costs.
