GS10789 GS11673 RVPA-67: Efficient and Clean Cooking for households in Nigeria

Audit Analysis

A Gold Standard improved cookstove project in Nigeria with VVB-confirmed additionality and a quantified 5% leakage deduction, but undermined by a verified usage rate (50.67%) far below the ex-ante assumption (85%), the absence of a buffer pool, and an extensive list of material findings and corrective actions spanning 30+ items. The project over-delivers relative to its lifetime ex-ante estimate, which is reassuring for credit validity, but the volume of documentation corrections and inter-document contradictions raises reliability concerns.

Project Description

Red Flags

• ⚠Verified usage rate of 50.67% is less than two-thirds of the 85% ex-ante assumption, indicating significant adoption barriers that were not adequately captured in the baseline
• ⚠30+ corrective actions and material findings across the verification and validation reports, including data transfer errors, copy-paste mistakes, and missing evidence for EIA exemptions and grievance mechanisms
• ⚠fNRB value contradicts between documents (0.8497 in verification report vs 0.64 in validation report), with the lower value potentially underestimating baseline emissions and overestimating reductions
• ⚠Stove lifetime (10 years) and attrition/replacement approach flagged as requiring justification in multiple material findings
