When users sink , an equal amount of VCUs in the Verra Registry has to be retired. After retiring VCUs on Verra, a certificate is generated that can be added your personal or business balance sheet to prove you have contributed to global climate goals or have compensated for your own unabated emissions.

Retiring a VCU permanently removes it from circulation, turning it from transferable inventory into an exclusive, claimable one-ton CO₂e reduction on your balance sheet. Until it's retired, a VCU remains merely a tradable instrument 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 do a transaction of 1.5 tons for example, which is not possible on Verra directly. Stellarcarbon built a mechanism that retires the fractions that remain pending for some time into a community certificate.
