Xinmi urban domestic waste gas harmless treatment and comprehensive utilization project

Audit Analysis
A VCS landfill gas project (ACM0001 v19.0) in China with a VVB-confirmed investment additionality test and measured baseline, but undermined by eight cross-document contradictions—most critically on whether gas capture is legally required and on the grid emission factor. The project delivered roughly 69% of its pro-rata ex-ante expectation for the elapsed monitoring period, indicating conservative crediting, yet key MRV parameters (FNRB, usage monitoring) are absent from the extracted record.
Red Flags
- Contradiction on capture_legally_required: the verification report (Aug 2024) states capture IS legally required, while the monitoring report (Aug 2024) states it is NOT—directly undermining the additionality claim if the VVB's finding is correct
- Grid emission factor discrepancy: the monitoring report uses 0.57205 tCO2/MWh while the verification report cites 0.8587 tCO2/MWh, a 50% difference that materially affects credit volume
- FPIC contradiction: the verification report confirms FPIC was conducted, but the PDD (May 2022) records it as not conducted—safeguards compliance is unclear
- FNRB method and usage monitoring method are not stated in the extracted record, limiting MRV transparency

Risk Indicators
VVB-confirmed investment test, but legal-requirement contradiction undermines robustness
LFG project—gas combusted on-site, no reversal risk; no reversal events reported
0% deduction with contradictory justification (quantified vs deemed negligible)
Project-specific baseline, measured per VVB; reassessment not yet due (10-yr interval)
Grievance mechanism present; FPIC status contradicted between verification report and PDD
CORSIA eligibility and CCP status both not stated in available documents
