A-Gas Singapore 1

Audit Analysis

A-Gas Singapore 1 is an ODS destruction project verified by TUV SUD under the ACR standard. The project type is inherently low-risk for permanence and leakage, and additionality was confirmed by the VVB via a combined test. However, the verification process surfaced 17 material findings—including several calculation errors in HBR/moisture and Tr&Dest emissions—and 11 corrective actions, indicating meaningful documentation and calculation weaknesses that were caught and remediated.

Project Description

Red Flags

• ⚠17 material findings reported in the verification report, including calculation errors in HBR/moisture methodology, Tr&Dest project emissions, GWP/SEi parameter references, and a With-Project Emissions value mismatch—all corrected but indicating initial calculation weaknesses
• ⚠Contradiction between the validation report (combined additionality test) and the PDD (regulatory surplus only) on the additionality test type, creating ambiguity about which test(s) were actually applied
• ⚠Contradiction between the validation report (leakage deemed negligible) and the PDD (leakage not applicable) on the leakage treatment basis
• ⚠No ex-ante lifetime ERR estimate found in the extracted record, limiting the ability to assess whether the 33,705 tCO₂e verified in a ~23-day monitoring period is consistent with the project's lifetime claim
• ⚠11 corrective actions required, spanning ownership clarification, calculation revisions, and documentation updates, suggesting the initial submission had significant gaps
