Audit Analysis

A Gold Standard improved cookstove project in Rwanda with VVB-confirmed additionality and no reversal events, but weakened by the absence of a buffer pool, a thin 0% leakage justification for a behavioral project, and several cross-document contradictions on FNRB values and crediting periods. The verified ERR exceeds the claimed figure, suggesting conservative initial estimates, though the basis of comparison is unclear without a lifetime ex-ante figure.

Red Flags

  • Leakage deduction of 0% justified only as 'deemed negligible' in the 2020 monitoring report, while the 2019 monitoring report described it as 'quantified' — an inconsistency that weakens the justification for a project where household behavioral reversion is a realistic risk
  • FNRB value contradicts between documents: 0.98 (national default, 2020 monitoring report) vs 0.85 (local field, 2023 PDD) — the more recent PDD value is lower and more rigorous, but the monitoring report used the higher value
  • Two different crediting periods appear across documents (2014–2021 in the 2020 monitoring report vs 2025–2030 in the 2025 validation report), creating ambiguity about which period the monitoring data applies to
