GS1247 VPA 193 Zambia Eastern Province Safe Water Project

Audit Analysis

The Zambia safe water VPA under Gold Standard PoA GS1247 has VVB-confirmed additionality and no reversal events, but is undermined by a 0% leakage deduction with a thin 'deemed negligible' justification, a project-specific baseline, and a very long list of corrective actions and material findings spanning water-quality failures, monitoring gaps, and documentation inconsistencies. The project delivered only about 24% of the pro-rata ex-ante expectation for the elapsed monitoring period, which is conservative but raises questions about baseline assumptions. Nine cross-document contradictions further erode confidence in the data record.

Project Description

Red Flags

• ⚠Leakage deduction of 0% with only a 'deemed negligible' justification, while the PDD originally specified a 5% deduction — the reduction is not adequately explained in the verification report
• ⚠27 boreholes failed initial water-quality tests and 21 required professional flushing, indicating significant operational reliability issues that could undermine the displacement assumption
• ⚠Nine contradictions across documents, including conflicting leakage treatments, ERR figures, usage-rate values, and crediting-period dates, reducing data reliability
• ⚠The verification report (Sept 2023) covers a monitoring period extending to Dec 2024, meaning the most recent ~15 months of monitoring data were not yet available at verification time
