Audit Analysis
The Sanya Landfill Gas Power Generation Project is a well-structured VCS project with VVB-confirmed additionality, no material findings, and no reversal events. However, the 0% leakage deduction is supported by contradictory justifications across documents, and the absence of a buffer pool leaves permanence risk partially unaddressed. Overall a solid but not exceptional project with moderate data gaps.
Red Flags
- Leakage deduction of 0% with contradictory justification: the verification report states leakage was 'not addressed' while the monitoring report (same date) states it was 'deemed negligible' — for a landfill gas project, unquantified leakage is a material concern
- CORSIA eligibility and CCP status are both unstated, creating uncertainty about dual-channel crediting risk
