Audit Analysis
This Gold Standard borehole project under a multi-country Improved Kitchen Regimes PoA shows a VVB-verified additionality assessment and no reversal events, but is undermined by a large number of unresolved corrective actions, multiple contradictions across documents in key parameters (leakage, FNRB, ERR figures, additionality test type), and the absence of a verified ERR figure. The project-specific baseline and the sector mismatch between a borehole activity and a cookstove methodology (TPDDTEC v.4.0) raise additional validity concerns.
Red Flags
- 30+ corrective actions remain open, spanning PoA-DD eligibility, additionality of retroactive VPAs, baseline survey evidence, and methodology applicability to water treatment technologies
- Additionality test type is contradictory within the same PDD (dated 2023-04-14): one section states 'combined' while another states 'investment'
- No verified ERR figure was found in any available document, making it impossible to confirm actual delivery against the claimed 144,650 tCO₂e
- Crediting period is contradictory: 2015–2022 (2020 monitoring report) vs 2025–2030 (2025 validation report), leaving the 2023–2024 monitoring period in a regulatory gap
- Leakage treatment is contradictory: 0% deduction with 'deemed negligible' justification (2020 monitoring) vs 5% quantified deduction (2023 PDD)
