BOLU LANDFILL GAS TO ENERGY PROJECT, TURKEY
Score Breakdown
Integrity
verified Additionality was confirmed by the VVB, and the more recent PDD describes a barrier test for the project.
missing Leakage treatment is not addressed, and buffer pool or reversal protection is not stated in the extracted record.
Transparency
verified A named VVB is identified, and the monitoring period is clearly stated in the 2024 monitoring report.
missing Total verified and claimed emission reductions are not found in the extracted record, limiting auditability.
Claim Safety
verified The project is a methane avoidance activity under Gold Standard, which generally lowers over-crediting risk relative to many removal projects.
missing Leakage justification is missing, and the project is marked as CORSIA-eligible without any CCP status stated, leaving some dual-claim uncertainty.
Documentation
verified The record draws on multiple document types, including the PDD, validation report, and monitoring report.
missing Six corrective action requests, four clarification requests, and one forward action request indicate notable documentation issues.
Detailed Analysis
Integrity
The monitoring and validation record supports a moderate integrity view because additionality was confirmed by the VVB, and the later PDD describes a barrier-based additionality case. Baseline method is stated as project-based, but baseline reassessment timing is not found, leakage is explicitly not addressed, and buffer pool or reversal protection is not stated. No material findings were reported, but the number of corrective and clarification requests suggests some weaknesses in project documentation.
Transparency
Transparency is mixed. The VVB is named as LGAI Technological Center, S.A., and the monitoring period is clearly given in the 2024 monitoring report, but the extracted record does not include verified or claimed emission totals. Public-facing MRV completeness is therefore limited by missing quantitative outputs and by the absence of usage monitoring details.
Claim Safety
Claim safety is moderate rather than strong. The project is a landfill gas-to-energy avoidance activity under Gold Standard, which is generally less exposed than many crediting types, but leakage is not addressed and no quantified deduction is available. The project is marked as CORSIA-eligible, while CCP status is not stated, so dual-claim risk is not fully resolved from the extracted record.
Documentation
Documentation quality is fair but not strong. The evidence set includes the PDD, validation report, monitoring report, and additional extracted material, and extraction confidence is medium rather than low. However, six corrective action requests, four clarification requests, and one forward action request indicate that the documentation package required substantial follow-up, and several key fields remain unstated.
Overall
I privileged the more recent documents where contradictions existed: for grievance mechanism, benefit sharing, additionality test type, and crediting period, the later documents were treated as more reliable because they are more recent and project-specific. The contradiction between the 2011 and 2017 PDD versions on additionality methodology is material, but it does not overturn the fact that the VVB later confirmed additionality. Overall, the project looks credible but not high-confidence because leakage is unaddressed, several core quantitative fields are missing, and the record contains multiple internal inconsistencies.
Audit Analysis
This is a certified Gold Standard landfill gas-to-energy project with VVB-confirmed additionality and a documented barrier test, which supports a moderate integrity score. However, leakage is not addressed, buffer pool and reversal information are missing, and the record contains several document-level contradictions that reduce confidence in the claims.
Project Description
Bolu Landfill Gas to Energy Project is a registered climate action project that generates verified emission reductions through sustainable practices. Developed under the rigorous requirements of the Gold Standard for the Global Goals, it ensures both measurable carbon mitigation and co-benefits aligned with the UN Sustainable Development Goals. The project follows robust monitoring, reporting, and verification (MRV) procedures to quantify its impact accurately. Its issued credits represent certified tonnes of CO₂ equivalent reduced or avoided, available for voluntary cancellation or secondary trading. By promoting environmental integrity and local socio-economic benefits, the Project contributes to global climate neutrality efforts while supporting sustainable community development in its host region.
Red Flags
- Leakage is explicitly marked as not addressed, with no quantified deduction found in the available documents.
- The record shows multiple contradictions across documents, including the additionality test type, grievance mechanism, benefit sharing, and crediting period.

Cosa migliorerebbe questo punteggio
- Publish the verified and claimed emission totals, along with the leakage assessment and any deduction applied.
- Provide a complete safeguards and permanence package, including buffer treatment, reversal monitoring, and a reconciled explanation of the document contradictions.
Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
