Advanced Refrigeration - ARS2021001

Audit Analysis
A US-based advanced refrigeration retrofit project under ACR with VVB-confirmed additionality and a reasonable leakage treatment, but undermined by six material documentation findings, four inter-document contradictions (including a baseline-method and crediting-period discrepancy), and several key MRV parameters left unstated. The project is functional but its documentation quality and data consistency fall well below the standard expected for a verified credit.
Red Flags
- Four contradictions across documents, including a baseline-method conflict (project-specific in the validation report vs. jurisdictional in the PDD) and a crediting-period mismatch (starting 2021-03-10 in the monitoring report vs. 2021-10-03 in the validation report), raising data-reliability concerns.
- Six material findings in the verification report, including arithmetic errors in the Project Plan capacity table, use of an outdated ACR template version, and missing risk-factor discussion for the aggregated project scope.
- All three ERR figures (claimed, verified, ex-ante lifetime) are identical at 39,881 tCO₂e, and the full lifetime estimate was delivered within a ~5.7-month monitoring window of a 10-year crediting period, which warrants scrutiny of whether the ex-ante estimate was properly calibrated.
