GS5658 VPA 12: Improved Cookstoves for Environmental Conservation in Southern Ethiopia

Audit Analysis

This Gold Standard cookstove VPA in Ethiopia presents serious integrity concerns, most notably a contradiction in which the 2025 verification report does not confirm additionality (while the 2023 report did), alongside 19 material findings and over 30 corrective actions flagging data inconsistencies, implausible usage-rate claims, and missing documentation. The verified emissions reductions for the monitoring period substantially exceed the pro-rata expectation from the lifetime ex-ante estimate, raising over-crediting risk. While a 5% quantified leakage deduction and a grievance mechanism are positive, the overall evidentiary picture is weak.

Project Description

Red Flags

• ⚠Additionality verification contradicts between the 2023 and 2025 verification reports: the 2025 report does not confirm VVB-verified additionality, while the 2023 report did. The more recent 2025 report is privileged, leaving additionality unconfirmed.
• ⚠The 2025 verification report lists 19 material findings and 30+ corrective actions, including incorrect GS ID on the monitoring report front page, inconsistent crediting-period dates, incorrect stove distribution numbers, missing formulas in the usage survey worksheet, and a claim of 100% usage rate deemed not plausible.
• ⚠Verified ERR of 20,008 tCO2e for a single 1-year monitoring period is approximately 217% of the pro-rata expectation (~9,210 tCO2e) derived from the 48,628 tCO2e lifetime ex-ante estimate over a ~5.3-year crediting period, suggesting potential over-crediting.
• ⚠FPIC was not conducted, and the 2025 verification report flags unresolved CIGM (Community Independent Grievance Mechanism) comments and a missing Objective Observer report.
• ⚠Two monitoring reports from the same date (2025-04-08) report different claimed ERR values (20,008 vs 7,026 tCO2e), indicating internal data inconsistency.
