Audit Analysis
The Dengzhou AMMS biogas project has a VVB-verified combined additionality test and no observed reversal events, but is undermined by the absence of a stated buffer pool, a project-specific modeled baseline, and a very high number of corrective actions (24) raised during verification. The ERR figures in the monitoring report and appendix are broadly consistent on a pro-rata basis, but the grievance mechanism appears to have been discontinued between the 2023 verification and the 2024 monitoring report, raising safeguards concerns.
Red Flags
- 24 corrective actions (15 CARs + 9 CLs) were raised during verification, indicating significant documentation and process gaps that had to be remediated before the verification could be closed
- Grievance mechanism reported as present in the 2023 verification report but absent in the more recent 2024 monitoring report, suggesting the mechanism was discontinued
- No buffer pool percentage is stated in any available document, leaving permanence risk unquantified for a biogas project
- CORSIA eligibility is confirmed while CCP status is not stated, creating potential dual-channel crediting risk
