Safe Water Programme – Nigeria – VPA 10

Audit Analysis

The Safe Water Programme in Nigeria has a confirmed investment-test additionality and a conservative verified usage rate (96.84% vs 90% assumed), but is undermined by a project-specific baseline, an unaddressed leakage justification, the absence of any buffer pool, and a verification report containing 22 corrective actions including cross-country reference errors (Kenya in a Nigerian project). The overall MRV quality is moderate with notable gaps in permanence safeguards and baseline robustness.

Project Description

Red Flags

• ⚠Verification report (2024-07-25) contains references to Kenya for baseline parameters in a Nigerian project, indicating a template or copy-paste error that undermines confidence in the MRV calculations
• ⚠Leakage deduction is 0% with justification recorded as 'not addressed' in the verification report, contradicting the monitoring report's claim of 'deemed negligible' — no quantitative or qualitative leakage analysis is documented
• ⚠22 corrective actions were required by the VVB, including wrong parameter values, incorrect dates, and sampling methodology that does not meet CDM Appendix 3 requirements
• ⚠The ex-ante lifetime ERR estimate is not found in any document, preventing a meaningful pro-rata delivery check against the 1,232,137 tCO₂e verified for the 11-month monitoring period
