GS7591 VPA 21 Central Mozambique Safe Water Programme

Audit Analysis

The Central Mozambique Safe Water Programme displaces firewood/charcoal use for water heating and has confirmed additionality with no reversal events, but is burdened by an unusually high volume of corrective actions, a 30,370 tCO2e over-issuance in an earlier monitoring period, and persistent non-compliance with methodology monitoring requirements. The project is broadly on track with its ex-ante estimates for the latest period, yet the sheer number of data-quality errors and inconsistencies across documents undermines confidence in the underlying MRV data.

Project Description

Red Flags

• ⚠Over-issuance of 30,370 tCO2e in Monitoring Period 1 due to incorrect calculation of borehole operating days; the project proponent deducted the excess in the current period, but the initial error signals weak internal QA.
• ⚠Project was in non-compliance with methodology requirements for parameter SDWS 23 (monitored quantity of safe water); multiple deviation requests were denied and the project was required to implement flow-meter or sensor-based monitoring after 30/06/2023.
• ⚠26+ corrective action requests, multiple forward action requests, and numerous clarifications raised across validation and verification cycles indicate systemic data-quality and reporting weaknesses.
• ⚠Contradiction in total ERR verified: 37,972 tCO2e (2026 verification report) versus 1,062,735 tCO2e (2025 verification report) — a ~28× discrepancy that, while likely attributable to different monitoring periods, raises questions about data traceability.
• ⚠Leakage deduction of 0% justified as 'deemed negligible' in the 2026 verification report, while the 2025 monitoring report characterises leakage as 'quantified' — an inconsistency in how leakage is treated across documents.
