Audit Analysis
A VCS-registered landfill methane recovery project (AMS-III.G v10.0) in China with VVB-verified additionality and a legally mandated capture obligation, but weakened by a project-specific modeled baseline, an unaddressed 0% leakage deduction with inconsistent justifications across documents, and a low extraction confidence rating that limits full verification of the record. The current monitoring period shows claimed and verified ERR matching at 32,594 tCO₂e, though the absence of a lifetime ex-ante estimate prevents a full pro-rata over-crediting check.
Red Flags
- Leakage deduction of 0% with justification shifting from 'not addressed' (2024 verification report) to 'deemed negligible' (2025 monitoring report) — no quantitative leakage assessment found in any document
- Minimum extraction confidence rated 'low', indicating at least one key document was poorly readable and the full evidentiary record could not be fully assessed
- Multiple contradictions between the April 2025 and October 2025 verification reports on safeguards, FPIC, grievance mechanism, and benefit sharing, suggesting documentation was retroactively amended
