Audit Analysis

A-Gas South Korea 3 is an ozone-depleting-substance destruction project under ACR with a VVB-verified combined additionality test and inherently permanent credit mechanism (destruction is irreversible). The core credit logic is sound, but documentation quality is weakened by low extraction confidence, an unidentified source document, and two minor material findings regarding export permits and cylinder counts. The project's identity is consistent once the methodology ('from International Sources') is read alongside the country field: ODS is sourced from South Korea and destroyed in Ohio, US.

Red Flags

  • Two material findings in the validation report require clarification: export permit validity dates for the R-11 shipment and a discrepancy in cylinder/drum counts between attestations and shipping documents.
  • Minimum extraction confidence is rated low, and one of the eight source documents is listed as 'unknown', reducing confidence in the completeness of the evidence base.
  • The monitoring period (6 weeks, Feb–Mar 2024) is very short relative to the 10-year crediting period, and no ex-ante lifetime ERR figure is available to benchmark the 74,143 tCO₂e verified against a pro-rata expectation.
