Efficient Fuel Wood Stoves for Nigeria

Audit Analysis

A Gold Standard fuel-wood stove project in Nigeria with VVB-confirmed additionality and quantified leakage, but hampered by a project-specific baseline, no stated buffer pool, an 8.35% user drop-out rate, and significant operational disruption from Boko Haram conflict. The project delivered roughly 9.5× the pro-rata ex-ante expectation for the short monitoring period, indicating very conservative crediting, yet deployed only 35% of the planned stoves. Multiple contradictions across documents and a self-report monitoring method temper confidence in the data.

Project Description

Red Flags

• ⚠Stove deployment fell to 4,370 units versus 12,500 planned (35% of target), driven by Boko Haram conflict and political instability, raising questions about the robustness of the ex-ante activity assumptions.
• ⚠An 8.35% user drop-out rate was recorded in MP8, and no new cooking demonstrations were conducted during the latest monitoring period, indicating weakening user engagement and potential reversion to traditional cooking.
• ⚠No buffer pool percentage is stated in any available document, leaving permanence risk for an energy-efficiency project (stove breakage, user reversion) unquantified.
• ⚠Usage monitoring relies on self-reporting per the 2020 verification report, a method with lower data reliability than the annual survey referenced in the 2018 report.
• ⚠Six contradictions were identified across documents, including conflicting crediting-period start dates, divergent ERR figures, and inconsistent leakage justifications, reducing overall data reliability.
