DelAgua Clean Cooking Grouped Project in Sierra Leone

Audit Analysis

The DelAgua Clean Cooking project in Sierra Leone is a well-structured cookstove project verified by a reputable VVB (Applus+), with a confirmed combined additionality test, no material findings, and no reversal events. However, the project-specific baseline, inconsistent leakage justification across verification reports, and a significant shift in the fuel non-replacement baseline (FNRB) method and value between the PDD and later verification reports introduce moderate over-crediting and data-reliability concerns.

Project Description

Red Flags

• ⚠FNRB value dropped from 0.95 (local field method, PDD 2022) to 0.68 (national default, verification report 2025), a 28% reduction that materially changes the baseline calculation basis
• ⚠Leakage justification regressed from 'quantified' in the May 2025 verification report to 'not addressed' in the March 2026 verification report, despite a 5% deduction still being applied
• ⚠Buffer pool percentage is not stated in any available document, leaving permanence risk unquantified
• ⚠Eight contradictions across extracted documents (usage rate, FNRB, ERR figures, crediting period, benefit sharing, leakage) indicate data-reliability issues that warrant closer scrutiny
