Grouped projects for Mekong River Delta Water Purifier
#22of 25 in Vietnam#517of 629 in Verra (VCS)#23of 26 in AMS-I.E
Audit Analysis
The Mekong River Delta Water Purifier project has a VVB-confirmed investment additionality test and a quantified 5% leakage deduction, but is undermined by an extensive list of material findings spanning data inconsistencies, misleading leakage statements, and gaps in safeguards documentation. The project-specific baseline, absence of a stated buffer pool, and a verified ERR that is roughly six times the pro-rata expectation for the monitoring period raise meaningful over-crediting concerns. Multiple contradictions across verification reports on FPIC, grievance mechanisms, and safeguards further erode confidence in the project's integrity.
Red Flags
- Extensive material findings (40+ items) including a 'misleading statement regarding leakage,' inconsistent fuel savings data, and conflicting claims on open-fire elimination
- Verified ERR of 1,196,518 is approximately 601% of the pro-rata expectation (~199,071) for the 8-month monitoring period against the 10-year crediting period, raising over-crediting risk
- Buffer pool percentage not stated in any available document, leaving permanence risk unaddressed
- Contradictions between verification reports on FPIC (true vs false), grievance mechanism (true vs false), and safeguards (true vs false) indicate inconsistent compliance documentation
- Usage monitoring method changed from self-report (2023 VR) to annual survey (2025 VR) without clear justification in the extracted record
