Audit Analysis

A-Gas V9 is an HFC refrigerant reclamation project in Ohio verified by First Environment, Inc. under ACR. Additionality was confirmed via a combined test, and the project type carries no carbon-stock reversal risk. However, material findings (incorrect GWP values), a 100% usage-rate assumption, a project-specific baseline, and contradictory leakage justifications between the PDD and validation report introduce moderate over-crediting and documentation concerns.

Red Flags

  • Material finding: incorrect GWP values for HFC-125 and HFC-227ea were used in the baseline emissions calculation (vintage 2021 applied instead of 2020), requiring corrective recalculation.
  • Usage rate is assumed at 100% with no independent measurement or verification of actual reclamation throughput.
  • Leakage justification is contradictory: the PDD states leakage is 'deemed negligible' while the validation report records it as 'not addressed,' leaving the 0% deduction without a clear, verified rationale.
  • No ex-ante lifetime emissions reduction estimate is available in the extracted record, preventing a pro-rata delivery check against the 154,340 tCO₂e verified for the ~5-month monitoring period.
