Audit Analysis
A CDM small-hydro avoidance project in Brazil with VVB-confirmed additionality and a low inherent reversal risk, but the record is marred by a significant discrepancy in verified emission-reduction figures across documents, a baseline-method contradiction, and two outstanding corrective actions. The project is broadly sound for its type, yet data-reliability issues prevent a higher confidence rating.
Red Flags
- Verified ERR figure of 695,355 tCO₂e in the merged record exceeds the PDD ex-ante estimate of 673,897 tCO₂e for the full 7-year crediting period, while the monitoring report (2022) reports only 361,252 tCO₂e for the 2016–2020 period — a three-way inconsistency that undermines confidence in the credit quantity.
- Two corrective actions remain open: the project proponent has not yet provided the history of installed-capacity changes or an explanation for the Ombreiras emissions-calculation discrepancy between the 2nd and 3rd monitoring periods.
- Baseline method is described as 'project-specific' in one monitoring report and 'jurisdictional' in another, creating ambiguity about the exact baseline construction.
