Score Breakdown
Integrity
verified The validation/verification record confirms additionality using an investment test and reports no material findings or corrective actions.
missing Leakage is applied as 0% but is not consistently justified across documents, and baseline reassessment timing is not stated.
Transparency
verified Claimed and verified emission reductions match (69,434), and the monitoring and crediting periods are clearly stated in the monitoring report (2022).
inferred CORSIA/CCP status is not stated in the extracted record, limiting clarity for downstream users.
Claim Safety
verified Claimed and verified ERs are identical for the monitoring period, reducing immediate over-issuance risk.
missing Project-specific baseline plus weak/inconsistent leakage narrative increases over-crediting and greenwashing risk.
Documentation
verified Multiple core documents are available (monitoring report, validation report, PDD, issuance) with high extraction confidence.
missing Some key quality fields are missing or unspecified in the extracted record (e.g., baseline reassessment timing; CORSIA/CCP status).
Detailed Analysis
Integrity
Additionality is relatively strong on paper: the validation/verification documentation indicates an investment test and confirms additionality by the VVB. The monitoring report (2022) shows no material findings and no corrective actions required, supporting MRV reliability for the period. Integrity is reduced by a project-specific baseline approach and the absence of any stated baseline reassessment date in the extracted record, plus inconsistent leakage treatment (0% deduction without consistent justification).
Transparency
The monitoring report (2022) clearly states the monitoring period (2014-06-20 to 2020-06-19) and the crediting period (2014-06-20 to 2024-06-19). Reported and verified emission reductions are consistent at 69,434, which supports transparency of issuance quantities. Transparency is limited by missing public-claim metadata in the extracted record, including CORSIA eligibility and CCP status.
Claim Safety
Because the verified ERs equal the claimed ERs (69,434) in the monitoring report (2022), there is no immediate sign of over-issuance within that period. However, the baseline is project-specific and the extracted record does not show when (or whether) it was reassessed, which can elevate over-crediting risk over time. The leakage approach is also a concern: a 0% deduction is applied while the monitoring report does not address leakage, weakening defensibility of claims.
Documentation
Documentation coverage is reasonably good: the extracted record includes a monitoring report, validation report, PDD, and issuance records, and the minimum extraction confidence is high. The monitoring report is dated 2022-10-12, which is reasonably recent relative to the 2014–2020 monitoring period. Documentation quality is still constrained by missing or unspecified fields in the extracted record (e.g., baseline reassessment timing, CORSIA/CCP status).
Overall
Overall quality is moderate: VVB-confirmed additionality and a clean verification outcome support credibility, but baseline and leakage weaknesses reduce confidence in the conservativeness of credited reductions. The key contradiction is on leakage justification: the monitoring report (2022-10-12) does not address leakage, while the validation report (2022-10-12) deems leakage negligible. For scoring, the monitoring report was privileged because it is the period-specific MRV document governing quantified ERs; this inconsistency indicates a documentation/reliability issue and was scored as a negative for integrity and claim safety.
Audit Analysis
This VCS hydropower project has VVB-confirmed additionality via an investment test and a clean verification outcome for the 2014–2020 monitoring period. However, leakage treatment is inconsistently documented across reports, and the baseline is project-specific with no clear evidence of reassessment timing, which increases over-crediting risk.
Project Description
Verra VCS - Koroglu Hydroelectric Power Plant is a run-of river type plant constructed on the Savrun River on the eastern part of the Meditarrenean region in Turkey. Since its commencement, project has been generating clean energy to the national grid and produced 69,434 tCO2 emission reductions during the 6-year monitoring period, 2014-2020. During the construction and operation, Koroglu project complied with all the environmental regulations and created high quality jobs to local people. Project owner, even, provided various contributions to villages and individual contributions to villagers; and one of the important contributions was the renewal of the village drinking water system. Project was also designed and has been operated in a way to protect the aquatic life of the Savrun river.
Red Flags
- Leakage is inconsistently handled: the monitoring report does not address leakage while the validation report deems it negligible, yet a 0% leakage deduction is applied.
- Baseline is project-specific and the timing of any baseline reassessment is not stated in the extracted record.

Cosa migliorerebbe questo punteggio
- Provide a consistent, explicit leakage assessment in the monitoring report (or cross-referenced annex) that matches the validation rationale and supports the 0% leakage deduction.
- Disclose baseline reassessment timing and any updates to grid emission factor inputs (including the reference year) to strengthen over-crediting risk controls and buyer confidence.
Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
