Carbon Retirements

When a business or individual chooses to compensate their emissions with carbon credits, the credits must be permanently removed from circulation. The process of retiring – and irrevocably removing from circulation – tokenized carbon credits can be done through the Toucan app UI or programmatically.

Only TCO2 tokens can be retired on Toucan. Carbon reference tokens must be redeemed for underlying TCO2 tokens. Retirements performed on Toucan will be synced with the Puro registry.

Developers looking to perform retirements using code should refer to our technical docs ->
