Audit Analysis
This Gold Standard improved cookstove project in Rwanda has a verified additionality assessment and an active VVB (SustainCERT), but is undermined by an extensive list of material findings spanning data-entry errors, calculation mistakes, and methodology compliance gaps. The assumed usage rate of 99% versus a verified 84.2% signals a meaningful over-crediting risk in ex-ante estimates, and the 0% leakage deduction is supported by contradictory justifications across documents. Multiple unresolved contradictions in ERR figures, safeguards documentation, and crediting-period dates further erode confidence in the project's data integrity.
Red Flags
- Assumed usage rate of 99% versus verified 84.2% — a 15-percentage-point gap that the verification report explicitly flags as causing 'considerably below estimated' emission reductions
- Over 30 material findings in the verification report, including duplicate stove IDs, incorrect data entry, calculation errors in PTDs and non-CO2 emission factors, and sampling design non-compliance
- Reversal events described as 'not addressed' in the 2022 verification report, contradicting the 2018 report's 'none reported'
- Crediting period dates inconsistent across verification reports (2017-05-17 vs 2017-07-11 start), and the listed crediting period (ending Jan 2019) does not align with the active monitoring period (Nov 2022 – Aug 2023)
