Audit Analysis

A-Gas 1-2021 is a CAR-registered ozone-depleting substance destruction project in Ohio, verified by SES, Inc. The verified destruction quantity (84.267 tonnes ODS-equivalent) matches the claimed figure, and the inherent irreversibility of ODS destruction eliminates reversal risk. However, a unit discrepancy between the monitoring and verification reports, a minor scale non-conformance noted as a material finding, and the absence of explicit additionality and baseline documentation in the available records limit confidence in the project's rigor.

Red Flags

  • Unit discrepancy: the monitoring report (2021-01-20) records the ERR as 84,267 while the verification report (2021-01-27) records 84.267 — almost certainly a kg-vs-tonne or decimal error, but it undermines data reliability
  • Material finding: beginning and ending weights for the Plas-1160 destruction event were taken from different scales, a non-conformance with Appendix D Item (a)(1) of the COP
  • One of the three source documents is listed as 'unknown', reducing traceability
  • Additionality assessment and baseline methodology are not explicitly documented in the available extracted records
