3.4 Net carbon sequestration
- Net project carbon sequestration shall be calculated within the relevant worksheet (Standard or Small Project) of the WCC Carbon Calculation Spreadsheet (includes 3.3 total project carbon sequestration adjusted for 3.2 leakage minus 3.1 baseline).
- The predicted number of carbon units by vintage shall be identified according to the project's verification schedule. These shall be divided into the contribution to the WCC buffer and the claimable carbon sequestration.
- The net carbon sequestered to date and carbon sequestered in the current vintage/ monitoring period shall be confirmed in the Monitoring Report. At year 5, this is based on the projected carbon sequestration. From year 15 onwards, this is based on field survey measurements.
Net carbon sequestration is checked at validation. It may be re-checked at verification if there are changes to leakage or predicted project carbon sequestration.
Net carbon sequestration is the total amount of carbon sequestered by the project which can be converted into carbon units. These are divided between the proportion that will contribute to the shared WCC buffer and the claimable carbon sequestration which is the amount the project can sell or claim. The number of units will be set out by vintage, or monitoring period, in the Project Design Document.
The WCC Carbon Calculation Spreadsheet helps project developers to calculate their net carbon sequestration. See 3.3 Project Carbon Sequestration.
