Antai Group Waste Gas Recovery for Power Generation Project (300303)

Audit Analysis

A Gold Standard waste-gas-to-power project in China with VVB-confirmed additionality and full delivery of claimed credits over its 10-year crediting period. However, the project carries significant quality concerns: over 30 material findings and 28 corrective actions were raised across verification cycles, the grid emission factor dates to 2006, leakage is dismissed as negligible with no quantification, and no buffer pool is in place. The overall picture is of a project that functionally delivered its claims but with weak methodological safeguards and documentation quality.

Project Description

Red Flags

• ⚠Grid emission factor of 0.9928 tCO2/MWh is from 2006; China's grid mix has shifted since then, potentially inflating the baseline
• ⚠Leakage deduction of 0% justified only as 'deemed negligible' with no quantified analysis, despite the project involving combustible waste gas that could theoretically be diverted
• ⚠Steam monitoring meters required by the PDD were never installed; the project chose not to claim ERs for cogeneration, indicating the monitoring plan was not fully implemented
• ⚠No buffer pool or permanence mechanism is documented for the project
• ⚠30+ material findings and 28 corrective actions across verification cycles indicate systemic quality-control weaknesses in the project's monitoring and reporting
