Infra-Red Automatic Refrigerant Leak Detection Efficiency Project
#31of 189 in Methane#112of 345 in United States#401of 1339 in Verra (VCS)
Audit Analysis
A VCS-registered fugitive refrigerant leak-detection project in the United States with a VVB-confirmed barrier additionality test and no inherent permanence risk, but undermined by an unaddressed 0% leakage deduction, 14 material findings, 14 corrective actions, and multiple cross-document contradictions. The project delivered exactly the claimed ERR for its monitoring period, and CORSIA eligibility is explicitly excluded, but the documentation quality and baseline specificity limit confidence in the credit's robustness.
Red Flags
- Leakage deduction of 0% with no justification stated in the 2024 verification report, while the 2024 monitoring report claims it was 'deemed negligible' — a direct contradiction between the two documents for the same period
- 14 material findings and 14 corrective actions identified in the 2024 verification report, including inconsistent GHG ERR quantification between the ERR sheet and monitoring report, and use of incorrect GWP values (IPCC AR4 instead of AR2) for the 2014 monitoring period
- No ex-ante lifetime ERR estimate found in the extracted record, preventing a pro-rata over/under-delivery check against the 104,401 tCO₂e verified for 2015–2020
- Baseline is project-specific and measured, with no reassessment date stated; the 2024 verification report does not confirm a baseline reassessment was performed
