A-Gas V5

Audit Analysis

A-Gas V5 is an HFC refrigerant reclamation project under ACR with VVB-confirmed additionality and inherent permanence, but is held back by a project-specific baseline, a significant discrepancy between the PDD's claimed ERR (185,621) and the verification report's verified ERR (754,484), and six material findings including a baseline calculation error. The 0% leakage deduction is reasonable for a physical-capture technology, and the three-year gap between the 2019 monitoring period and the 2022 verification report raises timeliness concerns.

Project Description

Red Flags

• ⚠The PDD (June 2022) states a claimed ERR of 185,621 while the verification report (July 2022) reports 754,484 — a 4× discrepancy that is not explained in the extracted record and undermines confidence in the ex-ante estimate.
• ⚠The verification report identified a baseline calculation error (CAR 2: missing GWPs and individual weights for each HFC type), meaning the original baseline may have been understated or overstated before correction.
• ⚠The crediting period differs between the issuance document (2019–2029, 10 years) and the verification report (2019–2034, 15 years), creating ambiguity about the actual crediting window.
