# Can I retire carbon pool tokens, like CHAR, to offset my emissions?

**No, carbon pool tokens like CHAR cannot be retired.** Only TCO2 tokens — which back each reference token — can be [retired](https://docs.toucan.earth/toucan/retire-credits) to make impact claims.

Instead, carbon pool tokens can be redeemed for underlying TCO2 tokens, which can then be retired using our app. Learn how to [redeem here](https://docs.toucan.earth/toucan/carbon-pools/deposits-and-redemptions), and how to [retire here](https://docs.toucan.earth/toucan/retire-credits).
