Score Breakdown

Integrity

verified Additionality was tested using an investment test and was confirmed by the VVB in the validation/monitoring record.

missing Leakage treatment is weak because the monitoring report gives a leakage deduction of 0% and says leakage is not addressed, despite a contradictory validation-report reference to quantified leakage.

Transparency

verified The project has both validation and monitoring documentation, and the monitoring report provides a verified issuance figure of 57,264 tCO2e for the period covered.

missing Usage monitoring is not stated, and the monitoring report contains multiple corrective actions, which limits confidence in the completeness of public MRV disclosure.

Claim Safety

verified The project is not CORSIA-eligible, which reduces one channel of downstream claim risk.

missing The baseline is project-specific rather than a clearly standardized or recently reassessed jurisdictional baseline, and the leakage contradiction raises over-crediting concern.

Documentation

verified Multiple official documents were available, including validation, monitoring, PDD, and issuance records, and extraction confidence is high.

missing The monitoring report still lists several corrective actions, and the crediting-period dates differ between validation and monitoring records.

Detailed Analysis

Integrity

The project’s additionality case is reasonably strong because the validation/monitoring record says an investment test was used and the VVB confirmed it. Permanence risk is low for a hydro project, but the evidence does not show a buffer pool contribution or any explicit reversal treatment, so that part is not fully documented. Integrity is pulled down by the leakage inconsistency: the monitoring report says leakage was not addressed and shows a 0% deduction, while the contradiction log says the validation report described leakage as quantified.

Transparency

Transparency is mixed. The monitoring report and validation report are both present, and the record includes a verified issuance total of 57,264 tCO2e, but usage monitoring is not stated and the monitoring period is only partially informative without the underlying monitoring method. The monitoring report also lists several corrective actions, which suggests the public documentation is not fully clean or self-contained.

Claim Safety

Claim safety is moderate at best. The project is not CORSIA-eligible, which helps, but the baseline is project-specific and there is no clear evidence of a recent reassessment. The leakage contradiction between the monitoring report and validation report is a meaningful over-crediting risk, and the absence of a stated usage monitoring method limits confidence in the claimed reductions.

Documentation

Documentation breadth is decent because the extracted record references validation, monitoring, PDD, issuance, and other supporting materials, and extraction confidence is high. However, the monitoring report still contains several corrective actions, including date and internal consistency fixes, which indicates the documentation was not fully polished. The crediting-period dates also differ between the validation and monitoring records, adding a small reliability concern.

Overall

I privileged the monitoring report for operational and post-validation facts because it is more recent, but I noted the validation report where it appears more specific on leakage treatment and earlier safeguard status. The contradictions on leakage, FPIC, grievance mechanism, safeguards, benefit sharing, and crediting period reduce reliability and justify a downward adjustment to the score. Because integrity remains above the gate threshold, the overall score is not capped, but the project still reads as moderate quality rather than high confidence.

Audit Analysis

The project has some solid elements, including VVB-confirmed investment-test additionality and no reported material findings, but the evidence base is weakened by a project-specific baseline, an unaddressed leakage justification in the monitoring report, and several corrective actions. Overall claim confidence is moderate rather than strong because the monitoring report and validation report disagree on leakage treatment, safeguards, and the crediting period, and I privileged the more recent monitoring report for operational facts while noting the older validation report where it appears more specific on methodology.

Project Description

Proponent: Arı Su Enerji Üretim A.Ş. Protocol categories: Energy industries (renewable/non-renewable sources) Protocols: AMS-I.D. Estimated annual GHG reductions: 24574 tCO2e Region: Middle East Registration date: 2021-05-11

Red Flags

  • The monitoring report says leakage was not addressed, while the validation report reportedly quantified it; this inconsistency reduces reliability.
  • Several corrective actions remain open in the monitoring report, including date, naming, staffing, and internal consistency issues.

Credit Vintages

Nessuna emissione registrata sul registro.

Cosa migliorerebbe questo punteggio

  • Publish a reconciled leakage assessment that explains the difference between the validation and monitoring reports and states the final applied deduction.
  • Resolve all open corrective actions and provide a clean, dated monitoring package with consistent crediting-period, staffing, and safeguard information.

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