Audit Analysis

This Gold Standard safe water supply project in Nigeria has a VVB-confirmed combined additionality test and documented safeguards, but sits at the validation stage with no verified emission reductions yet. Six corrective actions and three material findings from the validation report raise concerns about baseline parameter accuracy and usage assumptions. The absence of any monitoring or verification data, combined with a project-specific baseline and a thin leakage justification, limits confidence in the claimed 290,960 tCO₂e lifetime reduction.

Red Flags

  • Six corrective actions required at validation, including clarification of baseline parameters, usage assumptions, and justification for an older version of the fNRB calculation tool
  • No verified emission reduction data exists; the monitoring period has no end date and usage rate (assumed 0.9) has never been independently verified
  • FPIC was not conducted despite this being a community-level safe water programme in Nigeria
  • Leakage deduction is 0% with only a 'deemed negligible' justification, with no quantified analysis of water diversion or non-target use
