VPA 6 Kilifi Borehole Rehabilitation Project

Audit Analysis

The Kilifi Borehole Rehabilitation Project is a Gold Standard energy-efficiency project displacing charcoal and wood for water heating, with VVB-confirmed additionality, a recently reassessed project-specific baseline, and no reversal events. However, multiple open corrective actions, contradictory leakage justifications across documents, and several unresolved data gaps (buffer pool, CORSIA/CCP status, end-use tracking) moderate confidence in the overall claim. The project delivered approximately 118% of its pro-rata ex-ante expectation for the elapsed monitoring period, indicating a reasonably conservative baseline.

Project Description

Red Flags

• ⚠Leakage justification is contradictory: the verification report (Feb 2025) states 'quantified' while the monitoring report (Feb 2025) states 'deemed negligible,' both yielding a 0% deduction — the basis for the zero deduction is not clearly documented
• ⚠Multiple corrective actions remain open, including ensuring GHG emission reductions are not overestimated and applying conservative assumptions if required, indicating the VVB identified potential over-crediting risk
• ⚠CORSIA eligibility and CCP status are not stated in any available document, leaving dual-channel risk unassessed
• ⚠Crediting period is inconsistent between the PDD (2014–2028, 14 years) and the verification report (2018–2023, 5 years), creating ambiguity about the true project lifetime and ex-ante ERR basis
