Audit Analysis
The Gyapa Cook Stoves Project is a long-running Gold Standard energy-efficiency project in Ghana with confirmed additionality and no reversal events, but it carries a heavy legacy of data-quality issues, dozens of material findings across multiple verification cycles, and a project-specific baseline that limits confidence in the credit claims. The project is over-delivering relative to its ex-ante estimate, which is reassuring, yet the volume of unresolved corrective actions and parameter contradictions (usage rate, fNRB method, leakage basis) warrants caution.
Red Flags
- Over 80 material findings and 60+ corrective actions accumulated across verification cycles, indicating persistent monitoring and reporting weaknesses
- Usage rate contradiction: the PDD assumes 90% while the 2017 verification report records 100%, and the monitoring method shifted from 'assumed' to 'annual survey' over time
- fNRB method changed from 'local field' (2019) to 'national default' (2021) without clear justification in the extracted record
- CORSIA eligibility and CCP status are both unstated, leaving dual-channel risk unassessed
