Audit Analysis
The WM Energy Biogas Plant is a VCS-registered biogas project in Turkey validated by Bureau Veritas with a combined additionality test confirmed by the VVB. However, the validation process surfaced 22 corrective action requests covering methodological errors, incomplete project boundaries, and insufficient site-visit coverage, all of which were subsequently closed. Significant data gaps remain in monitoring parameters, FNRB methodology, and CORSIA/CCP eligibility, and four contradictions between the PDD and validation report introduce uncertainty about the project's true scope.
Red Flags
- 22 corrective action requests and 3 clarification requests were raised during validation, covering incorrect GWP values, wrong flare efficiency, incomplete project boundary, and site-visit coverage of only 4 out of 63 farms
- The PDD (2021) claimed 564,630 tCO2e while the validation report (2025) validated only 247,202 tCO2e — a 56% reduction that is not fully explained in the extracted record
- Monitoring period, FNRB method, and usage monitoring method are all absent from the extracted record
- Low extraction confidence indicates at least one key document was poorly readable, reducing reliability of the extracted data
