context

Despite growing demand for climate finance, carbon markets are limited by a lack of consistent, structured data. Today, there is no commonly accepted protocol for project and credit data, leaving the market fragmented, cumbersome to navigate, and expensive to participate in. This lack of standardization impedes transparency and collaboration across the value chain, from registries and verifiers to buyers and regulators, and undermines confidence in the quality and credibility of carbon credits. Without shared data definitions and infrastructure, the market cannot operate efficiently or scale to meet global climate goals.

 

There is broad recognition that to unlock the full potential of carbon markets, stakeholders need access to open, auditable, and interoperable data systems. CDOP responds to this need by creating the core data standard required to connect systems, reduce friction, and enable informed decision-making.

Our work

CDOP will be producing (1) a set of principles to inform the purpose, use, and development of (2) a common data schema, with definitions and rules that standardize data describing carbon crediting projects and carbon credits across markets, geographies and activity types (including applicable methodologies, project descriptions, and digital MRV formats), and (3) a governance framework for maintaining and updating the protocol.

The work is organized into two working groups:

principles & policies working group

The Principles & Policies Working Group is focused on developing principles and the governance framework.

OUTPUTS:

  1. Finalized CDOP Principles

  2. CDOP Principles development commentary

technical working group

The CDOP data schema is publicly available for market participants to adopt and implement into their workflows. Version 1.0 focused on standardizing pre-issuance data fields, the area most underserved by existing standardization efforts (see a visual reference to CDOP's unique value-add in the World Bank's Carbon Market Infrastructure Working Group report).

Version 2.0, launched at Climate Week NYC 2026, builds directly on that foundation — expanding coverage to 11 data categories, introducing a standardized entity model across project, stakeholder, registry, and issuance, and replacing a single overwritable status field with an auditable, versioned status history. Over time, CDOP will continue expanding to cover the entire carbon credit lifecycle.
