Advanced Refrigeration - ARS2023002

Audit Analysis

A multi-state US refrigeration project under ACR's Advanced Refrigeration methodology with VVB-confirmed additionality and a well-known verifier (TÜV SÜD America). The most significant concern is that the verified emissions reductions (70,324 tCO₂e) in a 7.5-month monitoring period essentially equal the entire 10-year lifetime ex-ante estimate (70,323 tCO₂e), representing roughly 16× the pro-rata expectation, which raises serious over-crediting questions. Documentation is reasonably complete with high extraction confidence, but several key MRV parameters (FNRB method, usage monitoring, leakage quantification) are not stated in the available record.

Project Description

Red Flags

• ⚠Verified ERR of 70,324 tCO₂e in a 7.5-month monitoring period equals the full 10-year lifetime ex-ante estimate of 70,323 tCO₂e — approximately 16× the pro-rata expectation for the elapsed period, raising a serious over-crediting concern
• ⚠Leakage is deemed negligible with no quantified deduction percentage stated in the monitoring report, and no explicit justification beyond the label 'deemed negligible'
• ⚠Four material findings and three corrective actions were identified in the monitoring report (2024-03-07), including corrections to baseline and project emissions figures in Section VI, indicating the initial reporting contained errors
