Audit Analysis
A VCS cookstove project in Zambia with VVB-verified additionality and a quantified 5% leakage deduction, but undermined by a major usage-rate contradiction between the PDD and validation report, an exact match between claimed and verified ERR that raises over-crediting suspicion, and the absence of a stated buffer pool or baseline reassessment date. The project is functional but carries moderate data-reliability and over-crediting risk.
Red Flags
- Usage rate of 0.9 in the validation report contradicts 0.0418 in the PDD — a 21-fold discrepancy that materially affects the carbon claim
- Total ERR claimed and verified are identical at 1,598,600 tCO₂e, suggesting the verified figure may have been copied rather than independently measured
- If 1,598,600 is the 10-year lifetime estimate, the 2-year monitoring period delivered 500% of the pro-rata expectation, which is implausibly high and warrants scrutiny
- No buffer pool percentage is stated in any available document, leaving permanence risk unquantified
