Water Purification System for Safe Drinking Water (SDW) in Cambodia

Audit Analysis

A VCS-registered water purification project in Cambodia with VVB-verified additionality and a quantified 5% leakage deduction, but undermined by nine cross-document contradictions—most critically a 40× gap between the PDD's lifetime ERR estimate (35,741 tCO₂e) and the verified 18-month figure (884 tCO₂e), which represents only ~16% of the pro-rata expectation. The verification report flags a non-permanence risk analysis while no buffer pool percentage is stated, and the PDD appears to describe an earlier iteration of the project (different crediting period, different leakage and usage assumptions).

Project Description

Red Flags

• ⚠Verified ERR of 884 tCO₂e over 18 months is only ~16% of the pro-rata expectation derived from the PDD's 35,741 tCO₂e lifetime estimate, raising questions about PDD validity or project under-performance
• ⚠Verification report reports a non-permanence risk analysis (reversal events 'reported') while no buffer pool percentage is stated in any document
• ⚠Nine contradictions across documents, including the PDD crediting period (2022-07-01 to 2032-06-30) differing from the verification report's period (2023-04-01 to 2033-03-31), suggesting the PDD may describe a prior project iteration
• ⚠CORSIA eligibility and CCP status are not stated in any available document
