Audit Analysis
A-Gas ODS-VER5 is an ozone-depleting substances destruction project in Ohio with VVB-confirmed additionality and inherent permanence (destroyed ODS cannot re-emit). The main weaknesses are the absence of any leakage treatment in the documentation and five material findings related to documentation errors (incorrect substance references, vintage-year formatting), all of which require corrective action. The project is otherwise well-documented with a known VVB and recent verification.
Red Flags
- Leakage is entirely unaddressed in the available documents — no deduction percentage and no justification are provided, despite the verification report being the primary source
- Five material findings in the verification report (2025-10-06) include references to CFC-13 and R-13 that are not part of the project, and vintage-year figures not split between 2024 and 2025, indicating documentation quality issues that require corrective action before credits are issued
