A-Gas V4

Audit Analysis

A-Gas V4 is an HFC refrigerant reclamation project in Ohio, US, verified by Ruby Canyon Environmental under ACR. Additionality is VVB-confirmed via a combined test, and permanence is inherent to the project type (destroyed/reclaimed HFCs cannot re-enter the atmosphere). The main concerns are a project-specific baseline (contradicting the PDD's jurisdictional claim), several minor material findings in the verification report, and the absence of stated FNRB and usage-monitoring methods.

Project Description

Red Flags

• ⚠Baseline method contradiction: the validation report (2021-09-10) states a project-specific baseline while the PDD (2021-08-30) describes a jurisdictional baseline — the more rigorous interpretation is unclear
• ⚠Six material findings in the verification report, including requests for specific sales orders (Johnson Supply, Ingersoll Rand), clarification of COA lab numbers, and confirmation that scales used match those in a prior version, suggesting gaps in the evidentiary chain
• ⚠Crediting period discrepancy: the validation report lists 2020-08-06 to 2030-08-05 while the issuance record shows 2019-11-01 to 2029-10-31, creating ambiguity about the actual crediting window
