A-Gas V17
#177of 345 in United States#77of 147 in American Carbon Registry (ACR)
Audit Analysis
A-Gas V17 is an HFC refrigerant reclamation project under ACR with a well-established methodology (v2.0) and VVB-confirmed additionality. However, the initial validation submission contained 22 material findings—including incorrect emission reduction calculations, missing Certificates of Analysis, and cylinder serial-number mismatches—all of which were subsequently corrected. The project-specific baseline, unquantified leakage treatment, and low document extraction confidence limit confidence in the overall data quality.
Red Flags
- 22 material findings in the validation report, including incorrect With-Project Emissions and Total GHG Emission Reductions in the Monitoring Report, missing Certificates of Analysis for HFC-125 and HFC-227ea, and cylinder serial-number mismatches across multiple purchase orders
- Leakage is deemed negligible with no quantified deduction or detailed justification in the available documents
- Low extraction confidence across the document set, with one document type listed as 'unknown', reducing reliability of the extracted record
