Advanced Refrigeration - ARS2025003

Audit Analysis

This ACR-registered advanced refrigeration project (multi-site, US) has a VVB-verified combined additionality test and a technology-based design with no carbon-stock reversal risk. However, six material findings—including inconsistent refrigerant charge sizes for three locations and errors in data sources—directly undermine confidence in the ERR calculation, and the leakage treatment is limited to a qualitative 'deemed negligible' claim without quantification. All three ERR figures (claimed, verified, ex-ante lifetime) are identical at 44,902 tCO₂e, which is unusual given the 3-month monitoring window within a 10-year crediting period.

Project Description

Red Flags

• ⚠Six material findings reported in the monitoring report, including inconsistent refrigerant charge sizes for three locations and errors in data sources and units of measurement, directly affecting the ERR calculation
• ⚠Leakage is only qualitatively 'deemed negligible' in the monitoring report and not addressed at all in the validation report; no quantified deduction or detailed justification is provided
• ⚠All three ERR figures (claimed, verified, ex-ante lifetime) are identical at 44,902 tCO₂e, which is atypical for a 3-month monitoring period within a 10-year crediting period and raises questions about whether the avoidance is truly one-time or whether the figures were not properly disaggregated
