Audit Analysis
The Nepal Biogas Support Program CPA 6 is a large-scale biogas project (18,504 digesters) under Gold Standard with VVB-confirmed additionality and a quantified 5% leakage deduction. However, the absence of a buffer pool, a project-specific baseline, multiple open corrective actions, and low extraction confidence across 55 documents introduce moderate risk. The verified ERR matches the claimed figure and the verified usage rate (93.81%) exceeds the assumed rate (89%), suggesting conservative crediting, but contradictions in ERR scope figures and an unresolved additionality-test-type gap temper confidence.
Red Flags
- CAR01 (SDG calculation spreadsheet) and the FAR for CP renewal of CPA 2–5 remain open, creating a risk of credit loss and incomplete SDG verification
- Min extraction confidence is rated low, meaning at least one key document was poorly readable, reducing reliability of the extracted record
- Additionality test type is not stated in the extracted record; the PoA is 'deemed additional' per a closed CAR, but the specific test (investment, regulatory, or barrier) is not documented
- Contradictions in total ERR figures within the same 2026 verification report (161,180 vs 421,520 claimed; 161,180 vs 381,686 verified) create ambiguity about the correct crediting scope
