Advanced Refrigeration - ARS2021002

Audit Analysis

This ACR Advanced Refrigeration project in the US replaces high-GWP refrigerants with low-GWP alternatives across multiple grocery and commercial sites. Additionality is confirmed by the VVB via a combined test, and the technology-based nature of the project eliminates carbon-stock reversal risk. However, the validation report surfaced 17 material findings and 19 corrective actions, leakage is only 'deemed negligible' without a quantified deduction, and the low extraction confidence in the source documents limits assurance on data completeness.

Project Description

Red Flags

• ⚠Leakage is classified as 'deemed negligible' with no quantified deduction percentage or detailed engineering justification in the extracted record, which is a notable gap for a refrigeration project where refrigerant leaks are a well-known emission source.
• ⚠The validation report (March 2023) lists 17 material findings and 19 corrective actions, including corrections to the crediting period description, net-of-leakage language, community impacts section, conversion-date discrepancies at three sites, and missing GWP evidence for R-507a, R-402a, and R-290 — indicating the initial project documentation contained substantive errors.
• ⚠Minimum extraction confidence across the six source documents is rated low, meaning at least one key document was poorly readable and the structured data may be incomplete.
