Audit Analysis
The project shows some strengths (VVB-confirmed additionality, recent baseline reassessment, and a 10% buffer) but has material weaknesses: reported reversal events, inconsistent treatment of leakage across documents, and CORSIA eligibility which raises double-claim risk. Documentation is adequate but some key quantitative items (claimed ERR, leakage deduction) are missing or contradictory.
Red Flags
- Leakage justification not addressed in most recent verification despite earlier quantified claim
- Reversal events reported, indicating non-permanence risk
- Project is CORSIA-eligible, raising double-claim risk and requiring careful registry controls
