Audit Analysis
A VCS biogas project (AM0073) in China with a VVB-verified investment additionality test and no non-permanence risk, but limited by a project-specific modeled baseline, an unquantified leakage deduction percentage, and the absence of any monitoring-period data. The validated ERR is conservatively lower than the original PDD estimate, reducing over-crediting risk. Low extraction confidence and missing CORSIA/CCP status limit confidence in the overall assessment.
Red Flags
- Leakage is described as 'quantified' in the validation report, but the actual deduction percentage is not stated in any available document, making it impossible to verify the magnitude of the leakage adjustment.
- The PDD (Oct 2023) reports a lifetime ERR of 2,320,409 tCO₂e while the validation report (Aug 2025) reports 1,646,638 tCO₂e — a 29% reduction that, while conservative, indicates a significant revision between the ex-ante estimate and the validated figure.
- Minimum extraction confidence is rated 'low', meaning at least one key document was poorly readable, reducing reliability of the extracted data.
- No monitoring period data is available; the project's crediting period began in June 2024 but no MRV results have been reported in the extracted record.
