Audit Analysis

The Safe Water Programme in Nigeria has a VVB-verified additionality assessment and documented safeguards (FPIC, grievance mechanism), but suffers from significant data gaps and contradictions. No verified ERR figure is available, multiple corrective actions were raised during verification, and the project-specific baseline combined with unaddressed reversal risk and a CORSIA-eligible status create meaningful over-crediting and dual-channel concerns.

Red Flags

  • No verified ERR figure found in any available document — the claimed 1,558,670 tCO₂e cannot be independently confirmed
  • Four contradictions across ERR, FNRB value, FNRB method, and usage rate indicate inconsistent reporting between the verification report and monitoring report
  • Reversal risk explicitly not addressed and no buffer pool percentage stated for a 5-year crediting period
  • Multiple corrective actions (CAR 01–03, CL#01) and findings (FAR#01–02) raised in the verification report, including sampling methodology and monitoring continuity issues
  • CORSIA-eligible with CCP status not stated, creating dual-channel crediting risk
