Advanced Refrigeration - ARS2023009

Audit Analysis

A US-based advanced refrigeration project with VVB-confirmed additionality (combined test) and a 10-year crediting period, but undermined by five material findings (including a technical inconsistency in cooling-capacity calculations), a leakage treatment that is contradicted between the monitoring and validation reports, and identical claimed/verified/lifetime ERR figures that raise over-crediting questions. Multiple verification parameters (FNRB, usage monitoring, CORSIA status) are absent from the record.

Project Description

Red Flags

• ⚠Verified ERR (77,286) equals the full lifetime ex-ante estimate for a monitoring period of only ~5 months out of a 120-month crediting period, implying ~25× the pro-rata expectation; while a one-time refrigerant-charge methodology could explain this, the identical figures across all three ERR fields warrant independent recalculation.
• ⚠The validation report (Sept 2025) does not address leakage, while the monitoring report (Aug 2025) states it is 'deemed negligible' — an unresolved contradiction in a sector where refrigerant leakage is a material risk.
• ⚠Five material findings were reported, including inconsistent cooling capacities in calculations versus as-built refrigeration schedules for two locations, indicating the ERR calculation may not reflect actual installed capacity.
