GS10789 GS 10790 VPA42: Efficient and Clean Cooking for households in Tanzania

Audit Analysis

A Gold Standard household cookstove project in Tanzania with verified additionality, a quantified 5% leakage deduction, and no reported reversal events, but undermined by an extensive list of material findings and corrective actions, multiple cross-document contradictions (notably in the fNRB value and ERR figures), and dual CORSIA/CCP eligibility that elevates double-claiming risk. The project is functional but carries moderate data-reliability concerns.

Project Description

Red Flags

• ⚠fNRB value contradicts between the verification report (0.8635, local field) and the validation report (0.64, national default) — a 35% discrepancy that materially affects credit quantities
• ⚠27 corrective actions and 40+ material findings across verification and validation reports indicate systemic documentation quality issues
• ⚠Project is both CORSIA-eligible and CCP-eligible, creating dual-channel double-claiming exposure
• ⚠Buffer pool percentage is not stated in any available document, leaving permanence risk unquantified
• ⚠Crediting period differs between the monitoring report (2022–2027) and the validation report (2024–2029), suggesting possible VPA/PoA confusion
