Audit Analysis
This ACR Advanced Refrigeration project in the US has a VVB-confirmed additionality assessment and a reasonable leakage treatment, but a critical discrepancy between the verified ERR for a single monitoring year and the 10-year lifetime ex-ante estimate raises serious over-crediting concerns. Documentation is reasonably complete with high extraction confidence, though four material findings and a crediting-period contradiction between documents indicate quality gaps.
Red Flags
- Verified ERR of 190,939 for a single ~1-year monitoring period is essentially identical to the 10-year lifetime ex-ante estimate of 190,938, implying the project delivered roughly 10× the pro-rata expectation for the elapsed period — a major over-crediting signal
- Crediting period dates conflict between the monitoring report (2023-08-26 to 2033-08-25) and the issuance document (2023-01-01 to 2033-12-31)
- Four material findings (CARs, ADR, CR) and two corrective actions were raised in the monitoring report, indicating documentation and quantification quality issues
