GS1247 VPA 19 Improved Kitchen Regimes: Gatsibo District Borehole Project, Rwanda

Audit Analysis

This Gold Standard improved-cookstove project in Rwanda has VVB-confirmed additionality and no reported reversal events, but is undermined by a significant leakage discrepancy (0% applied in monitoring versus 5% specified in the PDD), inconsistent usage-rate assumptions across documents, and a project-specific baseline. Multiple contradictions in key parameters (FNRB, leakage, usage rate, additionality test type) reduce confidence in the robustness of the credit claims.

Project Description

Red Flags

• ⚠Leakage deduction of 0% applied in the 2020 monitoring report contradicts the 5% specified in the PDD (2023), creating a potential over-crediting gap of up to 5% of claimed reductions
• ⚠Usage rate assumed at 100% in the 2016 monitoring report versus 80% in the PDD, with verified rates of 90% and 100% in two different 2020 monitoring reports — inconsistent application of the design assumption
• ⚠FNRB value of 0.98 (national default, 2020 monitoring) versus 0.85 (local field, 2023 PDD) — a 13% swing in a key credit parameter with no clear reconciliation
• ⚠Verification report is dated March 2018, predating the current 2025–2030 crediting period by seven years, raising questions about whether the verification is still representative
