Cataloluk HEPP
Score Breakdown
Integrity
verified Additionality was confirmed by the VVB, and the monitoring record states no extreme-event reversals were reported.
missing The monitoring report lists numerous corrective and clarification requests, and the reversal treatment is not addressed consistently across documents.
Transparency
verified The project has a named verifier, a defined monitoring period, and a verified emissions total of 36,774 tCO2e.
missing Key MRV details are missing or not stated, including the usage monitoring method, buffer pool percentage, and FNRB method.
Claim Safety
verified The record shows a leakage deduction of 0% with leakage described as negligible, and the project is marked CORSIA-eligible.
missing The baseline is project-specific rather than standardized, and contradictions around leakage and crediting period weaken confidence in the claimed volume.
Documentation
verified The file includes a substantial number of extracted facts and a recent monitoring report dated 2025-09-02.
missing Extraction confidence is low, evidence documents are not clearly identified, and the report contains many unresolved corrective actions.
Detailed Analysis
Integrity
The verification record supports additionality through an investment test and the VVB confirms it, which is a positive sign. The monitoring report also states no extreme-event reversal occurred, but reversal treatment is not consistently addressed elsewhere and the file contains many corrective and clarification requests, which weakens confidence in project integrity.
Transparency
Transparency is mixed because the project has a named verifier, a defined monitoring period, and a verified total of 36,774 credits, but several core MRV fields are missing. The usage monitoring method, buffer pool percentage, and FNRB method are not stated in available documents, which limits independent assessment of the monitoring quality.
Claim Safety
Claim safety is moderate at best. The project shows a 0% leakage deduction with leakage described as negligible, but the baseline is project-specific rather than a more robust standardized approach, and the contradictions around leakage treatment and crediting period reduce confidence in the claimed issuance volume.
Documentation
Documentation quality is weak because the extraction confidence is low and the evidence documents are not clearly identified in the record. The monitoring report dated 2025-09-02 is recent, but it also lists many corrective actions and clarifications, indicating incomplete or problematic documentation.
Overall
I privileged the more recent monitoring report for operational details, but I treated contradictions conservatively because they indicate reliability issues. For additionality, I gave more weight to the VVB-confirmed investment test than the older combined-test reference; for leakage and reversal treatment, I discounted confidence because the record conflicts on whether leakage was quantified and whether reversals were reported. The overall score is held down by low extraction confidence, missing MRV specifics, and the large number of corrective actions, even though the project has some positive integrity signals.
Audit Analysis
The project has some positive signals, including VVB-confirmed additionality, a stated leakage deduction of 0%, and no reversal events reported in the monitoring record. However, the file shows many corrective actions, low extraction confidence, missing key MRV details, and several contradictions that reduce confidence in the reported claims.
Project Description
Developer: ST Climate Type: Small, Low - Impact Hydro Size: Small Scale Crediting period: 2010-04-01 → 2031-03-31 Estimated annual credits: 17467 tCO2e SDGs: Goal 9: Industry, Innovation and Infrastructure, Goal 7: Affordable and Clean Energy, Goal 13: Climate Action
Red Flags
- The monitoring report records many corrective and clarification requests, including multiple CARs and FARs, which suggests material documentation or implementation issues.
- Several key items are inconsistent across documents, including additionality approach, benefit sharing, leakage treatment, reversal treatment, and crediting period.

Cosa migliorerebbe questo punteggio
- Publish a complete, reconciled MRV package that resolves the contradictions on additionality, leakage, reversal treatment, benefit sharing, and crediting period.
- Provide the missing monitoring details, including usage monitoring methodology, buffer pool treatment, and any jurisdictional or standardized baseline reassessment evidence.
Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
