Carbon Data Open Protocol
Standardizing carbon market data to improve integrity, interoperability, and scale.
CDOP is developing a open data protocol to increase transparency, consistency, and interoperability in carbon markets, enabling the scale needed to meet global climate targets.
The Carbon Data Open Protocol (CDOP) is a cross industry, multi-stakeholder collaboration designed to standardize data describing carbon crediting projects and carbon credits across markets, geographies, and activity types.
CDOP is supported by 52 leading organizations from the private, nonprofit, and public sectors. It draws on the work of complementary initiatives including the Climate Action Data Trust (CAD Trust), the ICVCM’s Continuous Improvement Work Program, the World Bank’s Carbon Market Infrastructure Working Group (CMIWG), and others.
CDOP is committed to maximizing alignment with emerging frameworks under Article 6 of the Paris Agreement and to developing a protocol that is maintained as a public good.
