Score Breakdown

Integrity

verified Additionality is confirmed by the VVB, and no material findings are reported in the monitoring report (2024-02-07).

missing Baseline is project-specific and the timing of any baseline reassessment is not stated in the extracted record; leakage treatment is inconsistent across monitoring reports.

Transparency

verified Claimed and verified ERs match for the stated monitoring period (46,908 for 2022-01-01 to 2022-06-27) in the monitoring report (2024-02-07).

missing Multiple contradictions across official documents (ER totals, grid factor, crediting period, leakage justification) reduce MRV clarity and comparability.

Claim Safety

missing CORSIA eligibility and CCP status are not stated in the extracted record, increasing uncertainty for downstream claims.

missing Conflicting grid emission factors and ER totals across documents elevate over-crediting/greenwashing risk.

Documentation

verified A relatively complete document set is present (PDD, monitoring report, validation report, issuance) with high extraction confidence and 22 documents used.

missing Five corrective action requests are listed in the monitoring report (2024-02-07), indicating documentation/controls needed improvement at verification.

Detailed Analysis

Integrity

The monitoring report (2024-02-07) indicates additionality was confirmed by the VVB and reports no material findings, which supports core integrity. However, the baseline is described as project-specific and the record does not state when the baseline was last reassessed, which weakens confidence in baseline validity over time. Leakage is recorded as a 0% deduction, but the monitoring reports conflict on whether leakage was quantified or not addressed, which undermines the robustness of leakage treatment.

Transparency

For the stated monitoring period (2022-01-01 to 2022-06-27), the monitoring report (2024-02-07) shows the same claimed and verified ERs (46,908), which is a positive MRV signal for that period. Transparency is reduced by multiple inconsistencies across documents, including conflicting grid emission factors and crediting period dates in recent validation/monitoring documents. Public-facing completeness is mixed because key eligibility labels (CORSIA/CCP) are not stated in the extracted record.

Claim Safety

Over-crediting risk is elevated because the grid emission factor differs between two 2024 validation reports (0.4616 vs 0.53323), and the verified ER figure also conflicts across documents (46,908 vs 373,493), suggesting possible boundary or aggregation confusion. Leakage is treated as 0% while the justification is inconsistent between monitoring reports (quantified vs not addressed), which increases the risk that claims overstate net climate benefit. CORSIA eligibility and CCP status are not stated in the extracted record, so buyers cannot easily position claims against those frameworks.

Documentation

The extracted record indicates a strong document base (PDD, monitoring report, validation report, issuance) and high extraction confidence, supporting a solid documentation score. At the same time, the monitoring report (2024-02-07) lists five corrective action requests (CAR 01–CAR 05), implying that documentation and/or controls required remediation during the assurance process. Several key fields (buffer pool, baseline reassessment timing, CORSIA/CCP status) are not stated in the extracted record, leaving notable evidence gaps.

Overall

Key contradictions materially affect confidence: (1) leakage justification is shown as not addressed in the 2024-02-07 monitoring report but quantified in the 2022-10-21 monitoring report; the more recent 2024 monitoring report is privileged, and the inconsistency lowers integrity/claim-safety. (2) Additionality test type is combined in the 2022-10-21 monitoring report but investment in the 2015-11-25 validation report; the validation report is privileged for additionality characterization, but the mismatch reduces reliability. (3) Verified ERs conflict (46,908 in a 2024 validation context vs 373,493 in the 2020-12-11 monitoring report); these likely refer to different periods, but because the documents do not reconcile the totals in the extracted record, this reduces transparency and claim safety. (4) Grid emission factor differs between 2024-11-11 and 2024-02-16 validation reports; the more recent 2024-11-11 value (0.4616) is privileged, but the discrepancy suggests parameter instability. (5) Crediting period conflicts between the 2024-02-07 monitoring report (2012-06-28 to 2022-06-27) and the 2024-11-11 validation report (2022-06-28 to 2032-06-27); the validation report is privileged for crediting-period definition, but the inconsistency is a major red flag for eligibility boundaries.

Audit Analysis

This VCS hydropower project has VVB-confirmed additionality and matched claimed vs verified emission reductions for the latest monitoring period, but several cross-document inconsistencies raise over-crediting and data-reliability concerns. Leakage treatment is inconsistent across monitoring reports, and key parameters (grid emission factor and even the crediting period) conflict between recent documents.

Project Description

The Cirakdami Hydroelectric Power Plant generates renewable electricity to be delivered to Turkey's National Power Grid by utilizing water resources. Located in Dereli Town, Giresun Province, Turkey, the project has an installed capacity of 49.1 MW. Over its ten-year crediting period (renewable twice), it is estimated to reduce GHG emissions by an average of 88,510 tCO2e per year and 885,100 tCO2e overall.

Red Flags

  • Large discrepancy in verified emission reductions across periods/documents (46,908 vs 373,493) indicates potential reporting/aggregation issues.
  • Crediting period dates conflict between monitoring and validation documents, creating uncertainty about eligibility boundaries.
  • Grid emission factor differs between two 2024 validation reports (0.4616 vs 0.53323), which can materially affect credited ERs.
  • Leakage is shown as 0% while leakage justification is inconsistent (quantified vs not addressed).

Cosa migliorerebbe questo punteggio

  • Publish a clear reconciliation table across documents showing monitoring periods, cumulative vs period ERs, and which totals correspond to which issuance requests (to resolve the 46,908 vs 373,493 discrepancy).
  • Provide a single authoritative, dated grid emission factor calculation and reference year consistent across validation/verification, and explicitly document leakage assessment (including why 0% is justified) in the latest monitoring/verification package.

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