Maracanã Small Hydropower Project

Integrity

The validation report (2020) indicates additionality was assessed via an investment test and confirmed by the VVB (RINA Services S.p.A.), which supports additionality robustness. However, the baseline is described as project-specific and the timing of any baseline reassessment is not stated in the extracted record, which weakens confidence in baseline validity over the 2019–2026 crediting period. Leakage is explicitly not addressed in the extracted record and no leakage deduction is provided, creating an integrity gap for an avoidance renewable energy project where indirect effects may need justification.

Transparency

Transparency is constrained because the monitoring period is not stated in the extracted record and neither claimed nor verified emission reductions are provided, preventing cross-checks between monitoring and verification outcomes. On the positive side, the validation record identifies the VVB (RINA Services S.p.A.) and specifies the methodology (AMS-I.D v18.0), which helps trace the intended MRV approach. The registry is indicated as CDM while the user states Gold Standard, but no discrepancy is flagged in the extracted contradictions list, so transparency remains limited rather than penalized for a documented conflict.

Claim Safety

Claim safety is moderated by the project being stated as not CORSIA-eligible, which reduces the risk of aviation-related double-claim channels. However, the extracted record lacks key quantification inputs/outputs (grid emission factor value, claimed/verified ER totals, and monitoring period), making it difficult to judge over-crediting risk. Leakage is not addressed, and safeguards elements (FPIC, grievance mechanism, benefit-sharing) are not evidenced, increasing reputational/greenwashing risk for end users making high-confidence claims.

Documentation

Documentation is mid-range: a dated validation report (2020-09-01) is present and the extracted record shows no material findings or corrective actions in that report. Still, several critical fields are not found in the extracted record (monitoring period, ER totals, leakage deduction, baseline reassessment timing), despite multiple documents being listed (validation report, PDD, and others). The minimum extraction confidence is medium, which suggests some limitations in document readability or extraction completeness and reduces confidence in the record’s completeness.

Overall

No explicit contradictions are listed in the extracted record, so no score adjustment is made for internal document discrepancies. The overall score is driven down primarily by evidence gaps in MRV/quantification (missing monitoring period and ER totals), unaddressed leakage, and absent safeguards/grievance documentation in the extracted record, despite VVB-confirmed additionality in the validation report (2020). Note: post-scoring gate rules may cap transparency if documentation were to fall below 3.0, but documentation is scored above that threshold here.
