Score Breakdown

Integrity

verified Additionality was confirmed by the VVB, and the project uses the ACM0001 methodology with a project baseline.

missing Leakage treatment is weak because the verification report says it was not addressed, and no buffer pool or reversal information is found.

Transparency

verified The project has a named VVB, a defined monitoring period, and a Gold Standard registry record.

missing Claimed versus verified emission reduction totals are not stated, and key monitoring details such as usage monitoring and baseline reassessment are missing.

Claim Safety

verified The project is an avoidance project in the methane sector, which generally lowers reversal risk compared with removals.

missing Leakage justification is inconsistent across documents, and no CORSIA or CCP status is stated, leaving residual double-claim and over-crediting uncertainty.

Documentation

verified Multiple official documents were used, including validation, monitoring, and verification reports, and safeguards are at least partially documented through FPIC and a grievance mechanism.

missing Extraction confidence is low, several key fields are not stated, and the verification report contains many corrective actions, which weakens documentation quality.

Detailed Analysis

Integrity

The verification report confirms additionality through a combined test and identifies the project as using ACM0001 with a project baseline, which supports the core project logic. Integrity is pulled down by the leakage treatment: the verification report says leakage was not addressed, while the later monitoring report says it was deemed negligible, so the evidence is mixed and not fully robust. No buffer pool percentage or reversal events are found in the extracted record, so permanence evidence is limited even for an avoidance project.

Transparency

Transparency is moderate because the project has a named VVB, a defined monitoring period, and a clear registry identity under Gold Standard. However, the extracted record does not state claimed versus verified emission reductions, usage monitoring method, or baseline reassessment timing, which limits auditability. The low extraction confidence also suggests at least one key document was difficult to read, reducing confidence in the completeness of the public record.

Claim Safety

Claim safety is weakened by the inconsistent leakage treatment: one document says leakage was not addressed, while a later monitoring report says it was negligible. The project is a methane avoidance activity, which is generally safer than removals, but the absence of CORSIA and CCP status means dual-claim risk cannot be ruled out from the extracted record. Missing values for usage rates and other operational parameters also leave some over-crediting uncertainty.

Documentation

Documentation quality is mixed. The record includes multiple official documents and shows safeguards elements such as FPIC, a grievance mechanism, and benefit sharing, but the extraction confidence is low and several key fields are not stated. The verification report also lists many corrective action requests and a forward action request, indicating that the documentation required substantial follow-up before issuance.

Overall

The project looks directionally credible because additionality was VVB-confirmed and the methodology and registry context are clear, but the evidence base is not clean enough for a high score. I privileged the more specific and later monitoring-report statement that leakage was negligible over the older verification-report statement that leakage was not addressed, but I still discounted the score because the contradiction itself signals reliability risk. I also privileged the verification report over the older validation report for the additionality test type and over the PDD for the crediting period because it is the later, project-level assurance document; the mismatch in dates and the low extraction confidence further justify a conservative assessment.

Audit Analysis

This is a certified Gold Standard landfill gas-to-electricity project with VVB-confirmed additionality and a project baseline, which supports moderate integrity. However, the record shows weak leakage treatment in the verification report, many corrective actions, low extraction confidence, and several missing or inconsistent data points that reduce confidence in the claimed climate benefit.

Project Description

The biogas power project is plant to be built close to Molu village of Koca Sinan district in the province of Kayseri in Turkey. The project aims at avoiding greenhouse gas (GHG) emissions from existing landfill area by collecting biogas to generate electricity. Thus, in addition to the direct avoidance of GHG emissions, further indirect emission reductions are achieved through the CO2- neutral replacement of fossil fuels used for power generation. The activity includes installation of landfill gas extraction system, an enclosed flare as well as a biogas driven genset for electricity production.

Red Flags

  • Leakage is described as not addressed in the verification report, even though the monitoring report later says it was deemed negligible.
  • The verification report records 44 corrective action requests and 6 clarification requests in one verification cycle, plus a forward action request for the next verification.

Cosa migliorerebbe questo punteggio

  • Publish a reconciled emissions accounting package showing claimed versus verified reductions, leakage treatment, and the basis for any deductions.
  • Provide a complete, readable set of validation, monitoring, and verification documents with explicit baseline reassessment, buffer/permanence treatment, and registry double-claim status.

Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
