The FCPF Methodological Framework requires countries to select appropriate arrangements to avoid double counting, including double issuance, double selling/use, or double claiming, in order to track the emission reductions. This ensures that any ERs that have been generated, monitored, and verified under the FCPF ER Program and paid for by the Carbon Fund are not used a second time by any entity for sale, public relations, compliance, or any other purpose unless otherwise agreed by the parties to the ER Payment Agreement and, where relevant, consistent with any applicable guidance adopted under the Paris Agreement.  

World Bank assistance to countries has included the technical assistance to design and implement regulatory frameworks to clarify ER titles and mitigate the risk of double counting. As part of this regulatory framework, specific systems are put in place to avoid double counting, issuance, and claiming, including the national REDD+ Programs, Projects Data Management System, and an ER Transaction Registry. The ER Transaction Registry has capabilities to register, track, and as appropriate retire or cancel ER units generated under FCPF ER Programs.

The World Bank Carbon Asset Tracking System (CATS) provides a strong and reliable architecture to create, govern, store, and maintain data; guarantees operational transparency and security; and mitigates double-counting risks for the ER units generated under the World Bank. CATS will work with other global registry providers (e.g., ACR, Verra) to maintain the strict registry requirements that uphold the principles that avoid double counting.
