Protocol version history

Why are there several Protocol versions?

Over time, the Climate Dividends Protocol has continuously evolved to incorporate methodological advancements and refined standards, resulting in several successive versions. When an organization validates a claim, this validation is formally tied to the specific, latest version of the Protocol in force at that time.

Throughout the validity period of the initial claim, any subsequent claims remain governed and verified under that same referenced version. In other words, companies enjoy the flexibility of grandfathering rights: while they are permitted and encouraged to transition to the most recent version of the Protocol, they are under no obligation to do so unless an updated version explicitly mandates an upgrade.

To ensure full transparency regarding the evolution of our framework, below is the list of previous versions of the Protocol:
