All PVCs generated are allocated their own serial number and are listed on the Plan Vivo Registry. Each PVC can only be retired once and be allocated one beneficial owner. The registry is managed by a third party, IHS Markit (a part of S&P Global).

Projects must also take steps to identify and prevent overlap with other GHG reducing projects or national, jurisdictional, or sub-national programmes, so prevent carbon benefits being claimed under multiple projects and/or programmes.

Finally, Plan Vivo is currently working with selected meta registry developers to ensure that PVCs are represented in this emerging space that should help better identify potential areas over credit and claims overlap.

The Standard will adapt and evolve over time to continue to minimise risks to double counting.
