Compensating for emissions
Let's not forget that whenever a business or individual wants to compensate their emissions with carbon credits, the credits need to be permanently removed from circulation. This prevents somebody from reselling the credits at a future point in time, falsifying the compensation claim. In the Toucan universe, the Carbon Offset module will take care of guaranteeing claims can only be made once by burning the
TCO2tokens that embody the right to that claim.
This means that a user can buy and hold a carbon pool token like NCT, and 2 years later burn them to take climate action with a carbon project of their liking (by redeeming and burning the
TCO2tokens locked in the Base Carbon Pool). This guarantees accurate carbon accounting and allows businesses to communicate clearly which projects they have supported—recorded on a public blockchain until the end of time. 💫
