Audit Analysis

A-Gas 2019-9 is an ozone-depleting-substance destruction project in Ohio verified by GHD Services under the ACR standard. The verification report records no material findings and no corrective actions, and the verified ERR exactly matches the claimed figure, but critical integrity details (additionality test type, baseline method, leakage treatment) are absent from the extracted record, limiting confidence in the underlying assumptions.

Red Flags

  • Additionality test type and VVB confirmation of additionality are not stated in any available document, leaving the additionality basis unverifiable from the extracted record.
  • Baseline method and baseline reassessment timing are not stated in the available documents, making it impossible to confirm the business-as-usual assumption for ODS release.
  • Leakage deduction and justification are not stated in the available documents; while leakage is less material for ODS destruction, its absence is a documentation gap.
  • The monitoring period (2019-09-15 to 2019-10-03) covers only about two weeks of a ten-year crediting period, providing a very narrow window of verified performance.
