When users sink , an equal amount of VCUs in the Verra Registry has to be retired. When retiring VCUs at Verra, a certificate is generated that can be added your personal or business balance sheet to show prove you are offsetting emissions.

Retiring a VCU permanently removes it from circulation, turning it from transferable inventory into an exclusive, claimable one-tonne CO₂e reduction on your balance sheet. Until its retired, a VCU remains merely a tradable credit with no impact on anyone’s carbon accounting.

Retirement in the Verra Registry only happens in whole units, but Stellarcarbon also provides the option to make fractional retirements. We allow users to create a retirement of 1.5 tonnes for example, which is not possible on Verra directly. Stellarcarbon built a mechanism that retires the remaining fractions into a community retirement.
