Audit Analysis

A Gold Standard safe drinking water supply project in Tanzania with VVB-verified additionality and well-documented safeguards, but significant gaps in verified emissions data, contradictory FNRB and usage-monitoring methods across documents, and a 0% leakage deduction that is difficult to reconcile with the project's reliance on sustained community use. The absence of any verified ERR figure prevents a meaningful over- or under-delivery assessment.

Red Flags

  • No verified ERR figure is available in any document, making it impossible to confirm whether claimed reductions are actually being delivered
  • FNRB method is stated as 'national default' in the monitoring report but 'local field' in the validation report — a methodological inconsistency that affects the emission factor applied
  • Usage monitoring is described as 'assumed' in the monitoring report but 'annual survey' in the PDD, and the assumed usage rate is 100% with no verified measurement
  • Leakage deduction is 0% with a 'quantified' justification, yet no quantified leakage figure or methodology is provided in the extracted record
