Safe Water Programme – Nigeria - VPA 82

Integrity

The validation report confirms additionality through VVB review, and the baseline method is identified as project-based with a baseline reassessment in 2021. That said, leakage is not addressed, reversal events are not addressed, and no buffer pool percentage is available, so permanence and leakage robustness are only moderate.

Transparency

The record identifies Earthood Services Private Limited as the VVB and gives a clear monitoring window for December 2024. But total ER claimed versus verified is not found in the extracted record, and the monitoring method is only described at a high level as an annual survey, which limits transparency.

Claim Safety

The FNRB value is close to the national default, which is a modest positive for claim conservatism. However, leakage justification is not addressed, usage-rate verification is missing, and the project is marked CORSIA-eligible, all of which raise over-crediting and claim-safety concerns.

Documentation

The evidence base is reasonably broad, with ten documents used and references to a validation report, appendix, and stakeholder consultation. Still, the validation report is older than the monitoring period, several fields are not stated in available documents, and the extraction confidence is only medium, so documentation quality is solid but not strong.

Overall

I privileged the validation report for additionality and baseline-related facts because it is the higher-priority assurance document, while the later monitoring-period values were used where they appeared more recent and specific. The contradictions on reversal events, usage monitoring method, leakage justification, FNRB, usage rate, and crediting period were treated as reliability issues and pulled scores down, especially for transparency and claim safety. Because integrity remains above the gating threshold, the overall score is not capped, but the unresolved leakage and permanence questions keep the project in the middle range.
