Grouped Projects For Cambodia Water Purifier

Audit Analysis

This Cambodia water purifier project (VCS-3052) carries severe integrity and claim-safety concerns, including a documented overlap with VCS project 2925, a 38-fold discrepancy in the number of purifiers between the validation and project description documents, and a verified ERR roughly 9 times the pro-rata expectation for the elapsed monitoring period. The project description was found to incorrectly describe improved cookstoves rather than water purifiers, and over 40 corrective actions were required by the VVB. While a 5% leakage deduction and VVB-confirmed investment additionality test are present, the volume and severity of material findings, contradictions across documents, and the double-claiming risk render the credits highly questionable.

Project Description

Red Flags

• ⚠Documented overlap with VCS project 2925, creating a direct double-claiming risk
• ⚠Discrepancy in number of water purifiers: 26,000 in the validation report vs 1 million in the project description (38-fold gap)
• ⚠Verified ERR of 198,312 tCO2e for a 6-month monitoring period is approximately 9.2× the pro-rata expectation derived from the 431,290 tCO2e lifetime ex-ante estimate over 10 years
• ⚠Project description incorrectly referred to improved cookstoves instead of water purifiers in multiple sections
• ⚠Over 40 corrective actions required by the VVB, including fundamental errors in baseline documentation, fNRB calculation, and parameter definitions
