Safe Water Programme – Nigeria - VPA 86

Integrity

The validation report from Earthood Services Private Limited confirms additionality using a combined test, which supports the project’s core integrity case. The baseline method is project-based and was last reassessed in 2021, but permanence and leakage controls are only partially evidenced because buffer pool coverage is not stated and the leakage deduction is not quantified in the extracted record. No unresolved material findings remain, which is positive, but the missing quantitative safeguards keep the score below strong-project territory.

Transparency

Transparency is moderate because the validation report identifies the verifier, methodology version 3.1, and the monitoring period start date, and the project is documented under Gold Standard. However, total verified emissions reductions are not stated, the monitoring period end date is missing, and usage monitoring relies on self-reporting rather than independently verified values. These gaps reduce the ability to trace the claim end-to-end.

Claim Safety

Claim safety is mixed. The project has a Gold Standard validation record with no unresolved material findings, which helps, but the extracted record does not provide verified emissions reduction totals, verified usage rates, or a quantified leakage deduction. The project is marked CORSIA-eligible, while CCP status is not stated, so dual-claim risk cannot be fully ruled out from the available evidence.

Documentation

Documentation quality is limited by low extraction confidence, which suggests at least one key source was poorly readable. Although 11 documents were used and the record includes a validation report, stakeholder consultation material, and an appendix, several important fields remain missing or unspecified, including buffer pool coverage and verified usage rates. Safeguards are at least partially documented through FPIC, a grievance mechanism, and benefit-sharing language, but the contradictory crediting period entries reduce reliability.

Overall

The project looks moderately credible but not high-confidence. I privileged the later crediting-period value from the 2024-04-12 document over the earlier 2023-06-29 version because it is more recent, but the contradiction itself still lowers reliability. Overall scoring is constrained by missing quantitative evidence on leakage, permanence, and verified output, plus low extraction confidence; the integrity score remains above the gate threshold, so no post-score cap is triggered.
