A-Gas V11
#221of 345 in United States#100of 147 in American Carbon Registry (ACR)
Audit Analysis
A-Gas V11 is an HFC reclamation and destruction project in Ohio with VVB-confirmed additionality and inherent permanence (destroyed HFCs cannot be re-emitted). However, the monitoring report identified a material double-counting error (5,583 lbs of HFC-227ea previously claimed under A-Gas V10), a project-specific baseline with no stated reassessment, and a 0% leakage deduction supported only by a thin 'deemed negligible' justification. The combination of these issues, along with low extraction confidence and multiple corrective actions, limits confidence in the verified reduction figures.
Red Flags
- Double-counting of 5,583 lbs of HFC-227ea (transactions RCP000014862 and RCP000010010) previously allocated to A-Gas V10, identified in the monitoring report and requiring removal from this project's ERR
- Leakage deduction of 0% with justification only 'deemed negligible' in the PDD and not addressed in the validation report, leaving the basis for the zero deduction unclear
- Five material findings in the monitoring report, including incorrect crediting periods and misidentified HFCs, indicating documentation quality issues that required corrective action
