akar.earthRetirement: Definition
What is carbon credit retirement? How credits are permanently removed from circulation to back a claim, what the record shows, and Indonesian notes.
Retirement is the permanent removal of a carbon credit from circulation in a registry, so that it can no longer be sold or transferred and its climate benefit is claimed by a named beneficiary. It is the final step in a credit’s life.
Why it matters
Buying a credit is not the same as using it. Only retirement prevents the same tonne from being sold or claimed twice. Retirement records are public on most registries, so buyers, auditors and NGOs can check that a company’s offset or contribution claim is backed by real retired units. Retirement statistics also show actual demand: a large stock of issued but unretired credits signals weak demand or low-quality supply.
How it works
- The credit holder selects credits in its registry account by serial number.
- It submits a retirement request stating the beneficiary, the purpose and often the reporting year.
- The registry moves the credits to a retirement account and publishes the record.
Claims made with retired credits should follow guidance such as the VCMI Claims Code. Our guide to avoiding greenwashing explains how to word claims.
Indonesia angle
Indonesian buyers using IDXCarbon retire units through the domestic system, where units are recorded in SRUK. Companies covered by the PTBAE-PU emissions trading scheme may use SPE-GRK offsets within limits set by the rules, which involves surrendering units for compliance. International buyers of Indonesian credits retire on Verra, Gold Standard or other registries. Where units are also authorised for international transfer, retirement may relate to corresponding adjustments, so check current rules under Perpres 110/2025.
Common mistakes
- Announcing offsets before credits are retired.
- Not naming the beneficiary in the retirement record, which weakens the claim.
- Retiring older vintages that no longer fit the buyer’s own claim standard.
- Confusing retirement with cancellation.

Frequently asked questions
Is retiring a credit the same as cancelling it?
Both remove credits from circulation. Retirement is done to make a claim, usually by or on behalf of an end user. Cancellation is often used for administrative reasons, such as covering a reversal or moving units between registries.
Can a company claim credits it bought but did not retire?
No. A credit only supports a climate claim once it is retired, ideally with the beneficiary, purpose and claim period stated in the registry record.
