Audit Analysis

This VCS water-purifier project in Vietnam has a confirmed investment-test additionality and a quantified 5% leakage deduction, but the verification report identified 24 material findings and 20 corrective actions spanning double-counting prevention, baseline calculation errors, and incomplete additionality documentation. The project delivered only about 63% of its pro-rata ex-ante expectation for the two-year monitoring period, and the lifetime estimate was revised downward from 592,840 to 401,560 tCO2e between PDD versions, raising over-crediting concerns. Multiple contradictions between the PDD, verification report, and monitoring report further erode confidence in the data.

Red Flags

  • 24 material findings in the verification report, including double-counting within households due to similar names, household size exceeding national averages, and inconsistencies between ex-ante values in the ER spreadsheet and the monitoring report
  • 20 corrective actions required by the VVB, covering baseline calculation errors, missing additionality cost data (declared commercially sensitive), incomplete stakeholder consultation documentation, and missing geodetic coordinates
  • Lifetime ex-ante estimate revised downward from 592,840 tCO2e (2023 PDD) to 401,560 tCO2e (2024 PDD), a 32% reduction, suggesting the initial estimate was overly optimistic
  • Double-counting prevention methodology was flagged as insufficient by the VVB, with a specific request for detailed explanation (CL 01)
