Score Breakdown

Integrity

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

missing Leakage is marked as not addressed in the latest verification report, and reversal events are reported.

Transparency

verified The project has a named verifier, TÜV SÜD South Asia Private Limited, and a clearly stated monitoring period from 2023-01-01 to 2025-05-31.

missing Claimed versus verified emission reduction totals are not stated in the extracted record, and the extraction confidence is only medium.

Claim Safety

verified The project uses ACM0002 version 21.0 under Gold Standard, which is a recognized methodology for grid-connected renewable energy.

missing Leakage justification is inconsistent across documents, and no CORSIA or CCP status is stated, leaving residual over-crediting and double-claim uncertainty.

Documentation

verified Multiple document types were used, including the PDD, validation report, verification report, monitoring report, and stakeholder consultation materials.

missing Several corrective actions were required, and the crediting period dates conflict across reports, reducing documentation reliability.

Detailed Analysis

Integrity

The project’s additionality case is moderately strong because the verification report says an investment test was used and that the VVB confirmed it. On the other hand, the latest verification report records reversal-related non-conformity risk and lists multiple CARs, while leakage is not addressed in the latest record. The baseline is project-specific rather than a more robust standardized or jurisdictional baseline, and no buffer pool percentage is stated in the extracted record.

Transparency

Transparency is mixed. The verifier is identified as TÜV SÜD South Asia Private Limited, and the monitoring period is clearly stated, but the extracted record does not provide claimed versus verified emission reduction totals. The absence of key quantitative MRV fields, together with only medium extraction confidence, limits confidence in public reporting completeness.

Claim Safety

Claim safety is weakened by inconsistent leakage treatment and missing eligibility status information. The latest verification report says leakage is not addressed, while an earlier report said it was negligible, so the more recent and therefore higher-priority document was privileged. No CORSIA eligibility or CCP status is stated, which leaves dual-claim risk unresolved even though the project is under Gold Standard and uses ACM0002 version 21.0.

Documentation

Documentation breadth is fair because the extracted record references several official documents, including validation, verification, monitoring, PDD, and stakeholder consultation materials. Still, the record shows multiple corrective actions and only medium extraction confidence, suggesting at least one key document was not fully readable. The crediting period also conflicts between reports, so the more recent verification report was privileged for the final period because it is later and more specific.

Overall

I privileged the latest verification report for conflicting items because it is more recent and appears to reflect the final assurance position. Specifically, I used the 2025-11-03 verification report over the older 2024-02-15 and 2021-12-14 records for reversal risk, leakage treatment, and crediting-period timing. The contradictions reduce reliability: leakage changed from negligible to not addressed, benefit sharing differs across reports, and the crediting period is inconsistent, so the overall score is held down despite a confirmed additionality test.

Audit Analysis

The project has some positive integrity signals, including an investment-test additionality claim confirmed by the VVB and a recognized Gold Standard methodology. However, the record also shows unresolved leakage treatment, reported reversal-related issues, and multiple corrective actions, which weaken confidence in the credited climate benefit. Documentation is moderate but not strong enough to offset the reliability concerns.

Project Description

Developer: Monsoon Sustainability Co. Ltd. Type: Wind Size: Large Scale Crediting period: 2021-11-30 → 2026-11-29 Estimated annual credits: 135655 tCO2e SDGs: Goal 4: Quality Education, Goal 7: Affordable and Clean Energy, Goal 13: Climate Action, Goal 8: Decent Work and Economic Growth

Red Flags

  • Leakage is not addressed in the latest verification record, despite an earlier document saying it was negligible.
  • The latest verification report reports reversal-related non-conformity risk and several CARs, indicating implementation and assurance weaknesses.

Cosa migliorerebbe questo punteggio

  • Publish a clear, quantified leakage assessment and reconcile the discrepancy between the older negligible-leakage statement and the latest not-addressed finding.
  • Resolve the crediting-period inconsistency and provide complete public MRV tables showing claimed versus verified emission reductions, along with explicit CORSIA and CCP status.

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