GS1247 VPA 140 Lango Safe Water Project

Audit Analysis

The Lango Safe Water Project is a mature Gold Standard energy-efficiency project (operational since 2016/2018) with VVB-confirmed additionality and no reported reversal events, but it is undermined by a 0% leakage deduction with no supporting justification, an exact match between claimed and verified ERR figures that raises independent-verification concerns, and ten cross-document contradictions that erode confidence in the data record. Multiple corrective actions remain open, including demonstration of grievance-mechanism effectiveness and water-quality remediation.

Project Description

Red Flags

• ⚠Claimed and verified ERR are identical (51,658 tCO₂e), suggesting the VVB may not have independently recalculated the emission reductions
• ⚠Leakage deduction of 0% with justification recorded as 'not addressed' in the 2025 verification report, while the PDD originally proposed a 5% deduction
• ⚠Ten contradictions across documents, including conflicting crediting-period start dates (2016 vs 2018), conflicting FNRB values (0.89 vs 0.80), and conflicting usage-rate figures (87.5% vs 99.5%)
• ⚠Multiple Forward Action Requests remain open, including demonstration of grievance-mechanism effectiveness and water-quality remediation at boreholes LAN090 and LAN114
• ⚠CORSIA eligibility is confirmed while CCP status is not stated, creating potential dual-channel crediting risk
