Score Breakdown

Integrity

verified Additionality was confirmed by the VVB using an investment test in the verification report.

missing Reversal events are not addressed, and no buffer pool percentage is stated for permanence protection.

Transparency

verified The monitoring period is stated, and the project was verified by Bureau Veritas Certification.

missing Usage monitoring method is not stated, and total claimed ERs are not available for comparison with the 39,355 verified ERs.

Claim Safety

verified Leakage deduction is stated as 0%, and the report says leakage was deemed negligible.

missing The project uses a project-specific baseline, and the leakage treatment is contradicted by an earlier document that reportedly quantified leakage.

Documentation

verified Four documents were used and the extraction confidence is medium rather than low.

missing The verification report contains 15 corrective action requests, 18 clarification requests, and 2 forward action requests, showing material documentation gaps.

Detailed Analysis

Integrity

The verification report confirms additionality through an investment test and says the leakage impact was deemed negligible, which supports the core crediting logic. At the same time, permanence is weakly documented because reversal events are not addressed and no buffer pool share is provided. The large number of corrective and clarification requests in the Bureau Veritas report also suggests the project needed substantial follow-up before the verification could be finalized.

Transparency

Transparency is mixed: the monitoring period is clearly stated and the project was verified by Bureau Veritas Certification, but key MRV details are missing. Usage monitoring method is not stated, total claimed ERs are not available, and the record does not provide a clear comparison between claimed and verified issuance. CORSIA eligibility is also not stated, limiting registry-level clarity.

Claim Safety

Claim safety is moderate because the report states a 0% leakage deduction and treats leakage as negligible, which reduces over-crediting concerns. However, the baseline is project-specific rather than a more conservative standardized baseline, and the contradiction on leakage treatment reduces confidence. CCP status is not mentioned and CORSIA eligibility is not stated, so dual-market claim risk cannot be ruled out from the extracted record.

Documentation

Documentation quality is limited by the many corrective and clarification requests in the verification report, even though four documents were used and extraction confidence is medium. The crediting period is not stated, which makes it harder to judge recency and completeness against the monitoring period. The presence of FPIC, grievance mechanism, and benefit sharing is positive, but the overall file still looks incomplete for a high-confidence assessment.

Overall

The project shows some credible elements, especially VVB-confirmed additionality and a documented monitoring period, but the evidence base is weakened by substantial corrective actions and missing MRV details. I privileged the 2013 verification report over the earlier 2011 document on leakage because it is more recent and is the higher-priority assurance document, but I still downgraded confidence because the contradiction indicates reliability issues. The overall score is also constrained by unresolved permanence documentation and incomplete transparency around issuance and eligibility.

Audit Analysis

This project has some positive integrity signals, including VVB-confirmed additionality, a stated project baseline, and no quantified leakage deduction. However, the verification report also records many corrective and clarification requests, and reversal risk is not addressed, which weakens confidence in the crediting claims. Transparency is limited by missing usage-monitoring details, no claimed-vs-verified issuance comparison, and incomplete registry/eligibility information.

Project Description

Developer: ARSIN Enerji Type: Small, Low - Impact Hydro Size: Small Scale Methodology: ACM0002 Grid-connected electricity generation from renewable sources Crediting period: 2010-01-01 → 2016-12-31 Estimated annual credits: 20000 tCO2e SDGs: Goal 13: Climate Action, Goal 9: Industry, Innovation and Infrastructure, Goal 7: Affordable and Clean Energy

Red Flags

  • The verification report lists 15 corrective action requests plus 18 clarification requests and 2 forward action requests, indicating substantial documentation and implementation issues.
  • Reversal risk is not addressed and no buffer pool percentage is provided, which is a concern for a hydropower project.
  • A contradiction exists on leakage treatment: one document indicates leakage was deemed negligible, while an earlier document reportedly quantified it; the later verification report was privileged because it is more recent.

Cosa migliorerebbe questo punteggio

  • Publish a complete issuance reconciliation showing claimed versus verified ERs, along with the registry records and any retirement/transfer history.
  • Provide explicit permanence and leakage documentation, including buffer pool treatment, reversal monitoring, and the basis for the negligible leakage conclusion.

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