GS1247 VPA 306 - Togo Safe Water

Audit Analysis

The Togo Safe Water project (5 VPAs, borehole-based safe water supply) has confirmed additionality and no reversal events, but is severely undermined by over 50 material findings, 60+ corrective actions, and 9 cross-document contradictions affecting key parameters (leakage, fNRB, ERR, crediting period). The verified ERR of 16,591 tCO2e for a 2-year monitoring period is roughly 5× the pro-rata expectation derived from the PDD's lifetime estimate of 9,919 tCO2e, a ratio that is suspicious given documented errors in ER calculation parameters (Cj, Xboil). Low extraction confidence and numerous open Forward Action Requests further erode confidence in the project's data integrity.

Project Description

Red Flags

• ⚠Over 50 material findings in the verification report, including errors in ER calculation parameters (Cj, Xboil) and baseline Qp,y value (7.5 vs 7 L/person/day)
• ⚠Verified ERR of 16,591 tCO2e is approximately 502% of the pro-rata expectation (3,306 tCO2e) derived from the PDD lifetime estimate of 9,919 tCO2e over a 6-year crediting period, raising over-crediting concerns
• ⚠Leakage deduction contradicts between documents: 0% in the verification report vs 5% in the PDD, with justification shifting from 'quantified' to 'deemed negligible'
• ⚠fNRB value contradicts: 0.87 (verification report, national default) vs 0.97 (PDD, local field) — a 12% difference that directly affects claimed reductions
• ⚠60+ corrective actions required, including fundamental ER calculation corrections, missing monitoring details (GPS, WQT frequency, CTF), and unresolved SDG reporting gaps
