GS1247 VPA 106 Improved Kitchen Regimes: Kayonza District Borehole Project, Rwanda

Audit Analysis

This Gold Standard borehole/kitchen project in Rwanda has VVB-confirmed additionality and basic safeguards (FPIC, grievance mechanism), but is undermined by 11 cross-document contradictions on key parameters (leakage, fNRB, usage rate, crediting period), the absence of any buffer pool, and a large backlog of open corrective actions. The ERR figures cannot be reliably reconciled across documents, and the 0% leakage deduction is contradicted by a 5% figure in the PDD, raising material concerns about the robustness of the credit claims.

Project Description

Red Flags

• ⚠11 contradictions across documents on leakage justification, fNRB value, usage rate, crediting period, and other key parameters severely undermine data reliability
• ⚠Leakage deduction is 0% in the 2021 monitoring report but 5% in the 2023 PDD, with the justification shifting from 'quantified' to 'deemed negligible' — an unresolved inconsistency
• ⚠Five Forward Action Requests (FAR 01–05) remain open, including the requirement to submit an fNRB report at VPA level and demonstrate monitoring applicability
• ⚠Crediting period is stated as 2015–2022 in the verification report but 2025–2030 in the 2025 validation report, creating ambiguity about which period the monitoring data applies to
