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 pool tokens such as CHAR 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 Toucan for Developers.

Guide to Retirement Through Toucan's App UI

1. Connect your wallet holding TCO2 tokens to our app at https://app.toucan.earth/. You'll then see your TCO2s displayed under the "My Carbon Assets" section. Click Retire.

2. Select how many TCO2s you'd like to retire, and then click Continue.

3. Add relevant information, including:

   1. The name of the individual or organization performing the retirement

   2. The name of the individual or organization on who’s behalf the retirement is for

   3. The wallet address on who’s behalf the retirement is for, if available

   4. A message to your retirement transaction (e.g. a reason; max. 200 characters)

4. Click Request retirement

5. Once submitted, your retirement will enter a pending state until finalized in the Puro Registry. You can track the status of your submitted retirement at https://app.toucan.earth/retirements. It typically takes 2-3 business days for a retirement to finalize.

6. Lastly, Toucan will issue you a retirement certificate, viewable from https://app.toucan.earth/retirements. You may also download the certificate as a PDF.
