Audit Analysis
A registered VCS landfill gas power generation project in China with VVB-confirmed additionality and no reversal events, but undermined by a 0% leakage deduction with inconsistent justification across documents, a project-specific baseline, and a notable contradiction on whether gas capture is legally required. The ERR figures are internally consistent for the current monitoring period, and the project is not CORSIA-eligible, reducing double-claiming risk.
Red Flags
- Leakage deduction of 0% with the verification report stating leakage was 'not addressed' while the monitoring report claims it was 'quantified' — the justification is inconsistent across the two most recent documents
- Contradiction on whether landfill gas capture is legally required: the PDD (2020) states it is, while the monitoring report (2025) states it is not — if legally required, additionality would be fundamentally undermined
- Grid emission factor of 0.6063 tCO2/MWh is from 2017 and has not been updated in the available record
