Conversion of SF6 To An Alternative Cover Gas In Magnesium Production In Eaton Rapids, MI and Strathroy, ON

Audit Analysis

This VCS project converts SF6 to Novec as a cover gas in magnesium production, with a solid regulatory additionality test confirmed by the VVB and no reversal risk inherent to the avoidance mechanism. However, the 2025 verification report lists over 30 corrective actions covering transcription errors, missing calibration records, inconsistent monitoring data, and monitoring-plan deficiencies, which significantly undermines confidence in the reported emission reductions. The project is not CORSIA-eligible and the 0% leakage deduction is justified as quantified, but the data-quality issues and project-specific baseline warrant caution.

Project Description

Red Flags

• ⚠Over 30 corrective actions in the 2025 verification report, including transcription errors across multiple tracking files, missing scale calibration records, duplicate data entries, and misstated activity data for magnesium melted and Novec consumed
• ⚠Primary records of weight measurements for gas cylinders and totes are not available for the entirety of the reporting period, and DNV was unable to cross-verify magnesium invoices against reported melt quantities
• ⚠The monitoring report contains inconsistencies with VCS template requirements, including missing SDG appendix, incorrect monitoring equipment identification, and unexplained inapplicability of Sections 2.2 and 2.3
