Audit Analysis

The Safe Water Programme in Nigeria is a Gold Standard energy-efficiency project with VVB-verified additionality and no reported reversals, but it carries moderate risks from a project-specific baseline, a 0% leakage deduction justified only as 'deemed negligible,' an unverified usage rate of 0.9, and the absence of a verified ERR figure to benchmark against the 290,960 claimed. Three material findings and one corrective action from the verification process indicate documentation gaps that remain open.

Red Flags

  • Total ERR verified is not stated in any available document, making it impossible to confirm whether the 290,960 claimed ERR is supported by monitoring data
  • Leakage deduction of 0% is justified solely as 'deemed negligible' without a quantified analysis, which is weak for a household water-supply project where users may revert to previous water sources
  • Usage rate of 0.9 is assumed but not verified; the monitoring report does not provide a verified usage rate
  • Three material findings (CL#01, CL#02, CAR#01) remain open, including a pending WPS lifespan declaration and incomplete safeguarding assessment
