Audit Analysis
The Çubuk Biogas Power Plant is a VCS-registered waste-to-energy project with a solid additionality case (combined investment and common-practice test confirmed by the VVB, IRR well below the 20% benchmark) and a defensible zero-leakage justification. However, the absence of any verified monitoring data, a project-specific modeled baseline, no buffer pool, and low document extraction confidence limit confidence in the credit claims. The project is in its early crediting period (2020–2027) and has not yet produced verifiable performance data.
Red Flags
- No verified ERR or monitoring period data found in any available document — the project's actual performance is unconfirmed
- Reversal events explicitly 'not addressed' and no buffer pool percentage stated, leaving permanence risk unquantified
- FPIC status contradicts between two PDD versions (2022 says conducted, 2025 says not conducted)
- Low extraction confidence across the document set, indicating at least one key document was poorly readable
Credit Vintages
No issuances recorded on the registry.
Risk Indicators
VVB-confirmed combined test, IRR 6.6% < 20% benchmark
No buffer pool, reversal not addressed (lower risk for waste
Zero deduction, quantified boundary justification
Project-specific modeled baseline, no reassessment yet due
Grievance mechanism present, FPIC status contradictory
CORSIA and CCP status both not stated
