Audit Analysis
The Linshu Biogas Recovery project is a VCS-registered biogas-to-power project with a VVB-confirmed investment additionality test and no material findings, but it relies on a project-specific baseline, a 0% leakage deduction whose justification shifted between documents, and an aging 2019 grid emission factor. One corrective action was raised, and several key parameters (buffer pool, CORSIA/CCP status, usage monitoring) are not stated in the available record.
Red Flags
- Leakage justification changed from 'quantified' in the validation report (2021) to 'deemed negligible' in the monitoring report (2023) while the deduction remained 0%, weakening the original quantification
- Grid emission factor of 0.7119 tCO2/MWh is from 2019, more than three years before the 2022–2023 monitoring period, risking over- or under-estimation of displaced emissions
- One corrective action (CAR) was identified in the verification report, indicating a non-conformity that required remediation
