Audit Analysis

A Gold Standard household water purifier project in Laos with VVB-confirmed additionality and quantified 5% leakage deduction, but undermined by a project-specific baseline, absence of a stated buffer pool, six material findings in the initial monitoring report, and multiple inter-document contradictions on FNRB method and leakage treatment. The first monitoring period delivered roughly 62% of the pro-rata ex-ante expectation, and the usage rate came in 7% below the design assumption.

Red Flags

  • The PDD (June 2023) characterises leakage as 'deemed negligible' with a 0% deduction, while the verification report (January 2024) applies a 5% quantified deduction — the project's own design document and its verification do not agree on the fundamental leakage treatment.
  • The validation report (dated March 2025) lists the FNRB method as 'local_field' while the verification report (January 2024) lists it as 'national_default'; the unusual chronology (validation after verification) raises questions about which assessment is authoritative.
  • Six material findings were raised in the initial monitoring report, including missing geographical coordinates for 18 target regions, unclarified WQT laboratory information, and incorrect SDG impact listings, all requiring corrective action.
