Standard Bodies & Registries

The organisations that set the rules and keep the record of every credit.

What they do

  • Publish the standards and methodologies that projects must follow.
  • Operate the registry where credits are issued, transferred and retired.
  • Approve or accredit the auditors who verify projects.

What to check before you rely on one

  • Does the registry show project pages and issuance records publicly?
  • Are methodologies published, versioned and open to comment?
  • Can you look up whether a specific credit has been retired?
