GS2404 International Water Purification Programme - CPA 3 Chlorine Dispensers in Uganda

Integrity

The verification report confirms additionality was checked by the VVB, and the project uses a combined test under AMS-III.AV Version 03, which supports the core project rationale. However, reversal events are marked as not addressed, and no buffer pool percentage is provided, so permanence is not well evidenced. Leakage is said to be quantified, but the actual deduction is not visible in the extracted record, limiting confidence in net credit integrity.

Transparency

The project has a named verifier, China Classification Society Certification Company, and a clear monitoring period from 2020-01-01 to 2020-12-31. Still, the extracted record does not state total emission reductions claimed or verified, which weakens traceability of the issuance claim. The monitoring approach also differs across documents: the verification report refers to self-reporting, while the monitoring report refers to an annual survey, suggesting inconsistent MRV description.

Claim Safety

Claim safety is moderate because the baseline was last reassessed in 2022 and the project uses a recognized methodology, but the baseline itself is project-specific rather than standardized. The project is marked CORSIA-eligible, while CCP status is not mentioned, so dual-market claim risk is not fully resolved. The fnrb value of 0.82 is reported, but the contradiction with an older appendix value and the lack of a clear leakage deduction keep over-crediting risk from scoring higher.

Documentation

Documentation breadth is fairly good, with evidence drawn from the appendix, PDD, validation report, verification report, monitoring report, and stakeholder consultation materials. The extraction confidence is medium, not high, and the record includes several contradictions, especially on additionality test type, usage monitoring method, fnrb method, and crediting period. The verification report also lists several CARs and CLs that were closed, which is acceptable, but it still indicates a non-trivial review burden.

Overall

I privileged the verification report for VVB-confirmed findings and the more recent monitoring report where it appeared to reflect updated operational data, but I treated the contradictions as a reliability penalty rather than resolving them in favor of one source. In particular, the crediting-period mismatch between the verification report and monitoring report is material, and the differing descriptions of usage monitoring and fnrb method reduce confidence in the consistency of the record. Because the project has solid additionality evidence but incomplete permanence, leakage, and issuance transparency, the overall score remains moderate rather than strong.
