GS1340 Efficient cookstoves in Burkina Faso – VPA-12 - tiipaalga F3PA cookstoves in Kourwéogo

Audit Analysis

A Gold Standard cookstove project in Burkina Faso with VVB-confirmed additionality and a quantified leakage deduction, but undermined by a significant usage-rate decline (from 95% assumed in the PDD to roughly 70–82% verified), reversal risk that was never explicitly addressed, and ten cross-document contradictions that erode confidence in the underlying data. The low extraction confidence and absence of a lifetime ex-ante ERR figure limit the ability to verify over- or under-crediting.

Project Description

Red Flags

• ⚠Usage rate assumed in the PDD (95%) is far above the verified rate (69.9% in 2022, 82.35% in 2025), creating a material over-crediting risk if the original assumption was used in early vintages
• ⚠Reversal events are marked as 'not addressed' in the verification record; for cookstoves, stove breakage and abandonment are the primary permanence risk and no buffer or credit-retirement mechanism is documented
• ⚠Ten contradictions across documents (leakage %, ERR figures, usage rate, crediting period, safeguards, grievance mechanism, monitoring method) indicate significant data-quality and record-keeping issues
• ⚠Minimum extraction confidence is rated 'low', meaning at least one key document was poorly readable, reducing reliability of the extracted facts
• ⚠No lifetime ex-ante ERR estimate was found in any available document, preventing a proper pro-rata over/under-delivery check
