Advanced Refrigeration - ARS2023005

Audit Analysis

This ACR-registered advanced refrigeration project in the southeastern US has VVB-confirmed additionality and a recent verification cycle, but suffers from a significant leakage documentation gap (contradicted between the verification and monitoring reports), an unexplained 1000% pro-rata over-delivery in the first monitoring period, and missing F-NRB and usage-monitoring data. The project is functional but carries moderate over-crediting and documentation risks.

Project Description

Red Flags

• ⚠The verification report (May 2025) states leakage was 'not addressed' while the monitoring report (May 2025) claims it was 'deemed negligible' — the VVB's own assessment contradicts the project's monitoring claim, leaving the leakage treatment unresolved.
• ⚠The project delivered 31,849 tCO₂e in the first 12-month monitoring period against a 10-year ex-ante lifetime estimate of 31,849 tCO₂e, meaning 1000% of the pro-rata expectation was met in year one — either the ex-ante estimate was materially understated or the activity was entirely front-loaded, both of which raise over-crediting concerns.
• ⚠Three corrective actions were required by the VVB (location counts, baseline refrigerant charge documentation, eligibility criteria alignment), indicating the project plan was not fully consistent with the ACR Standard at verification time.
