Audit Analysis

A-Gas 2018-5 is an ozone-depleting-substance destruction project in Ohio verified by GHD Services under the CAR registry. The verification report confirms the claimed 102,700 ERR units with no material findings or corrective actions, and the inherently permanent nature of ODS destruction eliminates reversal risk. However, the extracted record lacks explicit documentation of additionality, baseline methodology, and safeguards, limiting the depth of quality assurance that can be assessed.

Red Flags

  • Additionality test type and VVB confirmation of additionality are not stated in any available document, leaving the regulatory-compliance basis for additionality undocumented in the extracted record
  • No ex-ante lifetime ERR estimate is available, preventing a pro-rata over- or under-delivery check against the 10-year crediting period
  • Safeguards, grievance mechanism, and FPIC are entirely absent from the extracted record, though the US ARB regulatory framework likely covers these
