A-Gas V20

Audit Analysis

A-Gas V20 is an HFC refrigerant recovery project in Texas and Ohio with VVB-confirmed additionality and no carbon-stock reversal risk, but it is undermined by a striking discrepancy between the lifetime ex-ante estimate and the first-period verified figure (nearly the full 15-year estimate delivered in six months), seven material findings with five corrective actions, and an assumed 100% usage rate with no independent verification. The project's data quality and claim-safety profile are weak relative to its methodological soundness.

Project Description

Red Flags

• ⚠The verified ERR of 2,538,238 tCO2e for a six-month monitoring period is virtually identical to the 15-year lifetime ex-ante estimate of 2,538,235 tCO2e, implying the project delivered roughly 300× the pro-rata expectation for the elapsed period — a potential over-crediting or mislabelled baseline issue.
• ⚠Seven material findings were reported in the monitoring report, including duplicate work orders, missing EPA 608 certifications, missing Certificates of Analysis for R-410a batches, and a discrepancy between equipment summary and gas breakdown, with five corrective actions still open.
• ⚠Usage monitoring is listed as 'assumed' with a 100% usage rate and no independently verified usage figure, weakening the MRV chain for an HFC recovery project.
