A-Gas V3

Audit Analysis

A-Gas V3 is an HFC refrigerant reclamation project in Ohio with a VVB-confirmed combined additionality test and a technology-based permanence profile, but the verification report surfaced five material findings including a 5.05% calculation error and invoice discrepancies. The most serious concern is that the verified emissions reductions for a single monitoring year equal the entire ten-year ex-ante estimate, implying the project delivered roughly 1,000% of the pro-rata expectation, which raises substantial over-crediting risk. Two cross-document contradictions (baseline method and crediting period dates) further erode confidence in the data.

Project Description

Red Flags

• ⚠Verified ERR of 16,515 tCO₂e for a single 12-month monitoring period equals the full 10-year ex-ante lifetime estimate of 16,515, meaning the project delivered ~1,000% of the pro-rata expectation (1,651.5 tCO₂e) for the elapsed period — a 10× over-delivery that is not explained in the available documents.
• ⚠The verification report identified a 5.05% calculation error in total-weight columns and discrepancies in sales-invoice tank/cylinder quantities, both of which directly affect the ERR figure.
• ⚠The PDD describes the baseline as 'jurisdictional' while the validation report (one week later) classifies it as 'project-specific'; the more recent validation report is privileged, but the inconsistency undermines baseline confidence.
• ⚠Leakage is set at 0% and labelled 'deemed negligible' with no quantitative justification or sensitivity analysis in the extracted record.
