Mali Safe Drinking Water Program

Audit Analysis

The Mali Safe Drinking Water Program has a solid additionality foundation (combined test, VVB-verified) and no reversal events, but is undermined by a 100× discrepancy in the fNRB value between the verification and monitoring reports, a methodological contradiction on the fNRB source (national default vs. local field), and three material findings including an fNRB calculation error. The project over-delivered relative to its pro-rata expectation (146%), which is reassuring, yet the baseline data inconsistencies create meaningful over- or under-crediting risk.

Project Description

Red Flags

• ⚠fNRB value differs by a factor of 100 between the verification report (60.03) and the monitoring report (0.6003), indicating a probable unit error or calculation mistake that could invalidate the credit quantity
• ⚠fNRB method is stated as 'national default' in the verification report but 'local field' in the monitoring report — a fundamental methodological inconsistency
• ⚠Three material findings in the verification report, including an fNRB calculation not in line with CDM TOOL30, and five corrective actions still listed as required
• ⚠Leakage treatment is contradictory: 5% quantified deduction in the verification report versus 0% / 'deemed negligible' in the validation report
