Xiding AWMS GHG Mitigation Project

Audit Analysis

The Xiding AWMS project is a four-site swine biogas capture operation in China with VVB-confirmed additionality and a fundamentally sound mechanism, but it is undermined by ten material findings, nine corrective actions, a project-specific baseline with calculation gaps, and a 38.5% downward revision of the ex-ante estimate between the PDD and the validation report. The low extraction confidence and numerous missing fields (FPIC, CORSIA, CCP, FNRB, buffer pool) limit the depth of assurance available to a credit buyer.

Project Description

Red Flags

• ⚠Ten material findings and nine corrective actions in the verification report, including a baseline emission calculation that did not account for methane capture requirements under applicable regulations and an unclear barrier analysis inconsistent with the selected barrier type.
• ⚠The ex-ante ERR was revised down by 38.5% (from 190,532 tCO₂e in the PDD to 117,186 tCO₂e in the validation report), indicating the initial estimate was materially overstated.
• ⚠Minimum extraction confidence is rated low, meaning at least one key document was poorly readable and the extracted record may be incomplete.
