Question 1

What does "Carbon Registry" mean in the carbon market?

Accepted Answer

Database system that tracks the ownership and transfer of carbon credits to prevent double counting. Examples include Verra, Gold Standard, and American Carbon Registry. Registries are the bookkeeping backbone of the carbon market: they approve methodologies, oversee third-party verification, issue credits with unique serial numbers, and retire them when claimed. A credit outside a recognised registry cannot be reliably tracked and risks double counting. The registry behind a credit, whether Verra, Gold Standard, Puro.earth, Isometric, ACR, CAR, or another recognised standard, is a baseline quality signal.
