Score Breakdown

Integrity

verified Additionality was confirmed by the VVB, and the project uses a first-of-its-kind test under ACM0002.

missing Leakage is not addressed in the latest verification record, and buffer pool coverage is not stated in the extracted documents.

Transparency

verified The latest verification report is dated 2025-09-25 and covers monitoring from 2024-01-01 to 2025-03-31, with 58,394 verified ERs reported.

missing Public claim controls are incomplete in the extracted record: usage monitoring is not stated, and CORSIA/CCP status is not found.

Claim Safety

verified The project is an avoidance-type renewable energy project with a project baseline and a grid emission factor of 0.6703, which is directionally supportive of a conventional baseline approach.

missing Leakage treatment is weak because the latest record says leakage is not addressed, and the contradiction log shows an earlier document reportedly quantified leakage.

Documentation

verified The record draws on 28 documents, and the latest verification report reports no material findings and no corrective actions required.

missing Extraction confidence is only medium, and several important fields are not stated, including buffer pool coverage, baseline reassessment timing, and usage monitoring method.

Detailed Analysis

Integrity

The latest verification report confirms additionality through a first-of-its-kind test and says the VVB found no material findings, which supports the project’s core integrity case. That said, leakage is listed as not addressed in the latest record, and buffer pool coverage is not stated, so permanence/leakage robustness is only moderate. The project is an avoidance project, so reversal risk is inherently lower than for removals, but the missing buffer detail still matters.

Transparency

The documentation includes a recent verification report dated 2025-09-25 and a clearly stated monitoring period from 2024-01-01 to 2025-03-31, which helps traceability. However, the extracted record does not state the usage monitoring method, and both CORSIA eligibility and CCP status are not found, limiting public claim clarity. The verified emission total is available, but the claimed total is not stated in the extracted record, so reconciliation is incomplete.

Claim Safety

Claim safety is helped by the project type: a solar PV avoidance project under ACM0002 with a stated grid emission factor and a project baseline. The main concern is that leakage is not addressed in the latest verification record, while an earlier document reportedly quantified it, which creates uncertainty about over-crediting controls. With no stated CORSIA or CCP status, the project cannot be treated as especially claim-safe from the available evidence.

Documentation

The record is reasonably broad, with 28 documents used and a recent verification report that reports no material findings and no corrective actions required. Still, extraction confidence is only medium, which lowers confidence in the completeness of the record. Several key items are missing or not stated, including buffer pool percentage, baseline reassessment timing, and usage monitoring method, so the documentation package is incomplete.

Overall

I privileged the latest verification report for operational facts such as the latest verified emission total and the statement that leakage is not addressed, because it is the most recent and directly relevant assurance document. I also noted the contradictions explicitly: an earlier document reportedly quantified leakage, an earlier document reportedly described benefit sharing, and an earlier verified emission total differs from the latest one; these were treated as reliability concerns and pulled scores down. Because integrity remains above the low-risk threshold but documentation and transparency are only moderate, the overall score lands in the middle range.

Audit Analysis

This is a registered VCS solar project with a VVB-confirmed additionality claim and no material findings in the latest verification report. However, several key items are missing or inconsistent, including leakage justification, baseline reassessment timing, and public-facing claim controls, which keeps confidence moderate rather than high.

Project Description

GreenYellow Madagascar constructed and operated the Ambatolampy 20 MW solar PV project, which provides clean and renewable energy in Madagascar, reducing greenhouse gas emissions by 23,431 tCO2e per year and a total of 164,018 tCO2e over a 7-year crediting period. The project is the first of its kind on the island and helps reduce the country's reliance on imported fossil fuels.

Red Flags

  • Leakage is marked as not addressed in the latest verification record, despite an earlier document reportedly quantifying it.
  • There are contradictions in verified emission totals and benefit-sharing disclosure across documents, which weakens reliability.

Cosa migliorerebbe questo punteggio

  • Publish a clear leakage assessment or deduction rationale in the latest verification package and reconcile it with the earlier quantified leakage reference.
  • Disclose buffer pool treatment, usage monitoring method, and explicit CORSIA/CCP status, and resolve the emission-total and benefit-sharing contradictions across documents.

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