Audit Analysis
A CDM biogas project in Indonesia using well-established AMS methodologies with a reputable VVB (JQA) and a combined additionality test, but the record lacks verified emission reduction figures, monitoring reports, and buffer pool details. The project-specific modeled baseline and a significant discrepancy in claimed ERR figures (38,910 vs. 272,370 tCO₂e) introduce moderate over-crediting risk. Overall a mid-range project with reasonable technology but incomplete verification evidence.
Red Flags
- Total ERR claimed differs by a factor of ~7 between the validation report (38,910 tCO₂e) and an unidentified source (272,370 tCO₂e), creating uncertainty about the true credit volume.
- No verified ERR figures or monitoring reports were found in the extracted record, preventing confirmation of actual delivery against the ex-ante estimate.
- Buffer pool percentage is not stated in any available document, leaving permanence risk unquantified.
- Seven material findings (CL01–CL07) in the validation report, including clarification on methodology change from AMS-I.D to AMS-I.F and grid emission factor validity, indicate the VVB had unresolved questions at validation.
