Audit Analysis

A grouped cookstove project in Vietnam with confirmed additionality (investment test, VVB-verified) and a quantified 5% leakage deduction, but significant gaps in community safeguards (no FPIC, no grievance mechanism, no documented safeguards per the most recent verification report). A major discrepancy between the PDD's lifetime ERR estimate (38,536) and the verified ERR for a single monitoring period (218,129) raises serious over-crediting concerns, compounded by multiple internal contradictions across documents.

Red Flags

  • Massive ERR discrepancy: PDD states 38,536 lifetime credits while the verification report (2024-04-16) reports 218,129 verified for a ~1.67-year monitoring period — a ratio of roughly 34× the pro-rata expectation, suggesting either a data extraction error, a per-unit vs. total confusion, or genuine over-crediting
  • No FPIC conducted, no grievance mechanism, and no safeguards documented per the most recent verification report (2024-04-20) — a critical gap for a community-facing cookstove project in Vietnam
  • fNRB value dropped from 0.9403 (validation, 2022) to 0.6958 (verification, 2024) due to an uncertainty deduction, and the method shifted from national default to local field measurement — the basis of the emission factor is unstable across documents
  • Buffer pool percentage not stated in any available document, leaving permanence risk unquantified
  • PDD date (2025-08-11) post-dates the verification report (2024-04-16), which is chronologically anomalous for a Project Design Document and undermines confidence in the ex-ante baseline estimate
