Safe Water Programme – Nigeria – VPA 02

Audit Analysis

The Safe Water Programme in Nigeria has a VVB-verified investment additionality test and no reported reversal events, but suffers from a 0% leakage deduction with no documented justification, a project-specific baseline that contained Kenya-to-Nigeria parameter errors, and 22 corrective actions flagged by the VVB. Multiple contradictions across verification periods—particularly in the FNRB value and method, and in total emission reductions—undermine confidence in the data's internal consistency. The absence of an ex-ante lifetime estimate prevents a meaningful pro-rata over-crediting check.

Project Description

Red Flags

• ⚠Leakage deduction of 0% with justification recorded as 'not addressed' in the 2024 verification report, while the monitoring report claims it was 'deemed negligible'—no quantitative or qualitative leakage analysis is documented
• ⚠Corrective actions reveal baseline parameters were erroneously copied from a Kenyan project (xf, EFb, water sources, stove technologies), raising questions about whether the Nigerian baseline was properly adapted
• ⚠FNRB value changed from 0.96 (local field, 2023) to 82.3 (national default, 2024) with a simultaneous method change, and total ERR nearly doubled from 647,669 to 1,232,137 between verification periods without an ex-ante lifetime estimate to anchor the comparison
• ⚠22 corrective actions and multiple FARs (sampling methodology, chlorine tablet bias, operational-day identification) indicate significant monitoring-report quality issues that the VVB had to flag
