GS1247 VPA 64 Improved Kitchen Regimes: Kayonza District Borehole Project, Rwanda

Audit Analysis

This Gold Standard VPA sub-project (Kayonza District Borehole, Rwanda) has VVB-confirmed additionality and no reported reversal events, but is undermined by eleven cross-document contradictions in core parameters (fNRB, leakage, ERR, crediting period), five open findings requiring action, and the absence of a stated buffer pool. The volume of inconsistencies across the PDD, validation report, and monitoring reports significantly erodes confidence in the reliability of the claimed emission reductions.

Project Description

Red Flags

• ⚠Eleven contradictions across documents in fundamental parameters including fNRB (0.98 vs 0.85), leakage deduction (0% vs 5%), claimed ERR (38,968 vs 159,041), and crediting period (2015–2022 vs 2025–2030)
• ⚠Five open findings requiring action (FAR 01–05) covering SDG indicators, fNRB reporting, and monitoring justification remain unresolved
• ⚠Leakage deduction of 0% justified as 'deemed negligible' in the 2021 monitoring report, but the 2023 PDD specifies a 5% deduction — the more conservative figure was not applied
• ⚠Boreholes KAY001, KAY004, KAY011, KAY013-5, KAY017, KAY022, KAY026, KAY027, KAY030, KAY031, and KAY039 all experienced temporary breakdowns in 2017, indicating operational fragility
