Score Breakdown

Integrity

verified The PDD dated 2024-07-16 says additionality was confirmed by the VVB using an investment test, and the baseline was last reassessed in 2024.

missing Reversal risk is not addressed: reversal events are marked as not addressed and no buffer pool share is stated.

Transparency

verified The monitoring period is clearly stated as 2017-05-01 to 2024-04-30, and the VVB is named as Earthood Services Private Limited.

missing Verified and claimed emission reduction totals are not found in the extracted record, and the extraction confidence is low.

Claim Safety

verified Leakage is treated as negligible with a 0% deduction, which supports lower over-crediting risk.

missing The project is marked CORSIA-eligible, and the record does not provide enough public quantitative MRV detail to fully test claim robustness.

Documentation

verified The PDD is recent, dated 2024-07-16, and includes safeguards such as FPIC and a grievance mechanism.

missing Only one evidence document is clearly identified, and low extraction confidence suggests at least one key source was poorly readable.

Detailed Analysis

Integrity

The PDD dated 2024-07-16 reports additionality confirmed by the VVB through an investment test, which is a meaningful positive signal. The baseline was last reassessed in 2024, and no material findings or corrective actions were reported in the extracted record. That said, reversal events are not addressed, no buffer pool percentage is stated, and the contradiction log shows disagreement on additionality, leakage treatment, and the crediting period, which reduces confidence in the integrity case.

Transparency

The monitoring period is clearly stated as 2017-05-01 to 2024-04-30, and the VVB is identified as Earthood Services Private Limited. However, the extracted record does not provide verified or claimed emission reduction totals, and key MRV details such as usage monitoring method and FNRB method are not found. Low extraction confidence further weakens transparency because at least one source document was poorly readable.

Claim Safety

Claim safety is helped by the project’s 0% leakage deduction and the statement that leakage is deemed negligible. The project uses a project baseline rather than a more standardized jurisdictional baseline, and the record does not provide enough quantitative detail on emissions accounting to fully assess over-crediting risk. CORSIA eligibility is true, which means the project may still face channeling or market-claim scrutiny even though no direct double-registration evidence is shown.

Documentation

Documentation quality is mixed: the PDD is recent and includes safeguards such as FPIC and a grievance mechanism. On the other hand, only one evidence document is clearly identified in the extracted record, the extraction confidence is low, and the record lacks several key quantitative fields. The contradiction history also suggests that older and newer versions do not fully align on benefit sharing, additionality test type, leakage, and the crediting period.

Overall

The project scores in the middle range because it has some solid project-level safeguards and a VVB-backed additionality claim, but the evidence base is incomplete and internally inconsistent. I privileged the newer 2024 PDD for additionality, leakage, and crediting-period information because it is the most recent document, while noting that older documents conflict on those points. The contradiction set materially lowers reliability, and the low extraction confidence means the documentation should be treated cautiously.

Audit Analysis

The project has some positive integrity signals, including VVB-confirmed additionality, a recent baseline reassessment, and no material findings reported in the available PDD. However, reliability is weakened by low extraction confidence, missing verification totals, and contradictions across documents on additionality, benefit sharing, leakage treatment, and the crediting period. Overall claim safety is moderate because leakage is treated as negligible and the project is not clearly shown to have major double-claim risks, but CORSIA eligibility raises channeling concerns.

Project Description

Developer: RESADIYE HAMZALI ELEKTRIK ÜRETIM SANAYI VE TICARET ANONIM SIRKETI Type: Small, Low - Impact Hydro Size: Small Scale Methodology: AMS-I.D. Grid connected renewable electricity generation Crediting period: 2010-05-01 → 2017-04-30 Estimated annual credits: 22254 tCO2e SDGs: Goal 7: Affordable and Clean Energy, Goal 13: Climate Action, Goal 8: Decent Work and Economic Growth

Red Flags

  • Low extraction confidence and only one evidence document clearly identified, which limits confidence in the record.
  • Contradictions on additionality, leakage justification, and crediting period indicate inconsistent documentation across versions.

Cosa migliorerebbe questo punteggio

  • Publish the verification report and monitoring report with verified and claimed emission reduction totals, leakage calculations, and any corrective action details.
  • Provide a clear reconciliation of the conflicting documents on additionality, leakage treatment, benefit sharing, and the crediting period.

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