Advanced Refrigeration - ARS2022008

Audit Analysis

This ACR Advanced Refrigeration project (ARS methodology v3.0) has VVB-confirmed additionality via a combined test, but is undermined by five material findings—including calculation errors in refrigerant leak-rate parameters—and a striking discrepancy where the verified ERR for a single ~11-month monitoring period equals the entire 10-year lifetime ex-ante estimate. The project-specific baseline, unaddressed leakage in the validation report, and absence of FNRB and usage-monitoring data further weaken confidence in the credit quantity.

Project Description

Red Flags

• ⚠Verified ERR of 92,410 tCO2e for a single ~11.5-month monitoring period is approximately 10× the pro-rata expectation (~8,870 tCO2e) derived from the 10-year lifetime ex-ante estimate of 92,410 tCO2e, suggesting either a data error or a fundamental mis-statement of the lifetime baseline
• ⚠Five material findings in the verification report, including AERK,i values that did not incorporate separate leak rates for primary and secondary refrigerant loops, and inconsistent charge sizes for Wegmans #119, indicating calculation reliability issues
• ⚠Leakage was deemed negligible in the monitoring report but was not addressed at all in the validation report, leaving the justification unverified
• ⚠FNRB value, usage monitoring method, and CORSIA/CCP eligibility are all absent from the extracted record, limiting independent verification of the credit quantity
