GS1247 VPA 59 Improved Kitchen Regimes: Kayonza District Borehole Project, Rwanda

Audit Analysis

This Gold Standard borehole project in Rwanda has VVB-confirmed additionality and no reversal events, but is undermined by a fundamental methodology mismatch (a cookstove methodology applied to a water/borehole project), numerous unresolved contradictions in key parameters (FNRB, leakage, usage rate), and an extensive list of 30+ corrective actions that signal significant documentation gaps. The absence of verified emission reduction figures and the misalignment between the monitoring period and both crediting periods further weaken confidence in the project's quantified claims.

Project Description

Red Flags

• ⚠Methodology TPDDTEC v.4.0 is a cookstove methodology applied to a borehole/water project; corrective actions explicitly request justification of the methodology's applicability to water treatment technologies
• ⚠No verified emission reduction figures found in any available document; only claimed ERR of 38,968 tCO2e (2021 monitoring report) is available
• ⚠Monitoring period (2023–2024) does not align with either the old crediting period (2015–2022) or the new crediting period (2025–2030), creating a gap in the MRV chain
• ⚠30+ corrective actions remain open, including requests for baseline survey data, kitchen performance test results, and evidence of operational lifetime
• ⚠Contradiction in FNRB value (0.98 in 2021 monitoring report vs 0.85 in 2023 PDD) and FNRB method (national default vs local field) undermines confidence in the emission factor
