Audit Analysis

This Gold Standard improved-cookstove VPA in Bugesera, Rwanda has VVB-confirmed additionality and a recently reassessed baseline, but is undermined by a verified usage rate of 23.3% against a 90% PDD assumption, a 0% leakage deduction that is difficult to justify for a household energy-efficiency project, and a large volume of unresolved material findings and cross-document contradictions. The project is operational and monitored, but the gap between design assumptions and field reality, combined with documentation inconsistencies, limits confidence in the robustness of the credit claims.

Red Flags

  • Verified usage rate of 23.3% is only about one-quarter of the 90% assumed in the PDD, indicating the design-phase adoption assumption was severely over-optimistic and raising questions about whether the claimed ERR of 13,090 tCO₂ already reflects the low actual usage rate.
  • Leakage deduction of 0% with a 'deemed negligible' justification is inconsistent with the PDD's own 5% leakage provision and with the expected behaviour of households who may continue using traditional stoves alongside improved ones.
  • Twelve cross-document contradictions were identified across leakage treatment, ERR figures, usage rates, fNRB values, crediting-period dates, and benefit-sharing descriptions, indicating poor internal consistency in the project documentation.
  • The total verified ERR figure is not present in the extracted record; only the claimed figure of 13,090 tCO₂ is available, preventing an independent over- or under-delivery check.
  • Dozens of material findings and corrective actions remain open, including unresolved FAR items on SDG indicators, fNRB reporting at VPA level, and monitoring-option justification.
