GS 12239 VPA-1 Amazi Meza Rwanda Water Supply Project For Schools
Score Breakdown
Integrity
verified Additionality was confirmed by the VVB using a combined test, which is a meaningful positive signal.
missing The verification process recorded several corrective actions and clarification requests, and reversal events are not addressed in the available record.
Transparency
verified The monitoring report provides a verified emission reduction figure and a defined monitoring period, which supports traceability.
missing Total claimed emission reductions are not stated, and the monitoring approach relies on an annual survey rather than a fully transparent continuous record.
Claim Safety
verified The project uses a stated project baseline and reports a national-default FNRB value of 84.85, which is at least documented.
missing Leakage is only justified as negligible, and the contradiction record shows another source treated leakage differently, increasing over-crediting risk.
Documentation
verified The record includes a monitoring report, stakeholder consultation material, and seven documents used in extraction, with high extraction confidence.
missing Several key fields are not stated, including buffer pool coverage, baseline reassessment timing, and total claimed emission reductions.
Detailed Analysis
Integrity
The monitoring report confirms additionality through a combined test and the VVB, which supports the project’s core integrity case. At the same time, the verification process recorded three corrective actions plus clarification requests, and reversal events are not addressed, so permanence and implementation robustness remain only moderately supported. Leakage is described as negligible, but the lack of quantified deduction weakens the integrity assessment.
Transparency
The monitoring report dated 2024-12-11 provides a verified emission reduction total and a clear monitoring period from 2023-06-26 to 2024-03-31. However, total claimed emission reductions are not stated in the extracted record, and the annual survey approach is less transparent than more granular monitoring. The documentation is usable, but not fully complete for public scrutiny.
Claim Safety
Claim safety is helped by the documented project baseline and the use of a national-default FNRB value of 84.85. Still, leakage is only said to be negligible rather than quantified, and the contradiction record shows a different treatment of leakage in another document, which raises over-crediting concerns. CORSIA eligibility is not stated and CCP status is not mentioned, so dual-market claim risk cannot be ruled out from the extracted record.
Documentation
The evidence base includes a monitoring report, stakeholder consultation material, and seven documents used in extraction, with high extraction confidence. FPIC and a grievance mechanism are both documented, which improves the completeness of the file. Even so, several important items are not stated, including buffer pool coverage, baseline reassessment timing, and total claimed emission reductions, limiting documentation quality.
Overall
I privileged the monitoring report for the usage-monitoring and leakage descriptions because it is the most recent and directly relevant source, while noting that the contradiction record shows an earlier or alternative document treated those items differently. For leakage, I gave more weight to the monitoring report’s explicit statement that leakage was deemed negligible, but reduced confidence because the contradiction suggests inconsistent treatment across documents. Overall quality is moderate: the project has real strengths, but the corrective actions, missing fields, and document inconsistencies prevent a high-confidence score.
Audit Analysis
The project has some strong quality signals, including VVB-confirmed additionality, FPIC and grievance mechanisms, and a verified emission reduction figure. However, several corrective actions were raised, leakage treatment is only described as negligible, and key items such as buffer pool coverage and reversal handling are not stated in the available documents.
Project Description
Developer: SweetSense Inc. Type: Energy Efficiency - Domestic Size: Small Scale Methodology: GS Methodology for emission reductions from safe drinking water supply Crediting period: 2023-06-26 → 2028-06-25 Estimated annual credits: 60000 tCO2e SDGs: Goal 8: Decent Work and Economic Growth, Goal 1: No Poverty, Goal 3: Good Health and Well-Being, Goal 4: Quality Education, Goal 13: Climate Action, Goal 6: Clean Water and Sanitation
Red Flags
- Multiple corrective actions and clarification requests were raised in the verification process, which weakens confidence in the reported results.
- Leakage is described as negligible in the monitoring report, but the contradiction record shows another document treated leakage differently, creating a reliability concern.

Cosa migliorerebbe questo punteggio
- Publish a clearer leakage assessment with a quantified deduction or a stronger technical justification, and reconcile the contradictory leakage treatment across documents.
- Disclose the full verification trail for corrective actions, baseline reassessment timing, buffer pool treatment, and any CORSIA/CCP status to improve claim safety and documentation quality.
Questi suggerimenti indicano quali prove pubbliche aggiuntive potrebbero migliorare il livello di confidenza di questa valutazione. Non garantiscono un punteggio futuro più alto.
