GS10789 GS11673 RVPA-63: Efficient and Clean Cooking for households in Nigeria

Audit Analysis

This Gold Standard cookstove project in Nigeria has VVB-confirmed additionality and a quantified 5% leakage deduction, but is undermined by a project-specific baseline, no buffer pool, a significant fNRB discrepancy between documents (0.85 vs 0.64), and a verified ERR roughly five times the pro-rata ex-ante expectation for the monitoring period. The verification report lists over thirty material findings and corrective actions, including calculation errors, baseline fuel inconsistencies, and unresolved double-counting questions, which collectively erode confidence in the robustness of the credit claims.

Project Description

Red Flags

• ⚠Verified ERR of 119,441 tCO₂e for a ~4-month monitoring period is approximately 5× the pro-rata expectation derived from the ex-ante lifetime estimate of 358,068 tCO₂e (358,068 × 4/60 ≈ 23,871), a discrepancy explicitly flagged in the verification report as a 'significant increase in VERs compared to ex-ante estimates.'
• ⚠fNRB value of 0.8497 in the verification report versus 0.64 in the validation report represents a 33% difference in the fuel non-replacement baseline, directly affecting the magnitude of claimed reductions.
• ⚠Over thirty material findings and corrective actions were raised in the verification report, including calculation errors in the ER sheet, baseline fuel inconsistencies (LPG vs charcoal), and unresolved double-counting prevention mechanisms.
• ⚠Baseline is project-specific rather than jurisdictional, and the fNRB is derived from a national default with a noted discrepancy against FAO website data.
