Required documentation for carbon credits | Change Climate Help Center

All carbon credit transactions must have an attestation form signed by the provider/broker. This attestation form serves as a proof of purchase and retirement, and provides information needed to confirm that the credits meet the requirements of the Certification Standard.

In addition (or in the event that an attestation form is unavailable), you may provide the following for all carbon credits that you purchase:

Registry report (via hyperlink or screenshot) showing carbon credits retired on your behalf AND a payment receipt showing amount paid per credit
OR
Fully executed purchase contract AND payment receipt for credits purchased. A valid purchase contract must indicate either (a) that the certifying entity has completed a purchase of all required carbon credits or (b) has a contractual obligation to complete the purchase of all required credits within 12 months (ie. a payment plan). Installment purchases should be spaced at least quarterly and weighted evenly across the 12 month period. If on a payment plan, an attestation form is also required - see above.
