Shangcai Xima Biogas Recovery and Utilization Project

Audit Analysis

The Shangcai Xima biogas project has a VVB-confirmed additionality assessment and a registered status under VCS, but the verification report identifies 12 material findings and 4 corrective action requests related to monitoring gaps, outdated IPCC guidelines, and missing calculation elements. The project delivered its claimed 159,234 tCO₂e for the 2022–2023 monitoring period, yet the underlying data quality concerns and low extraction confidence across 16 documents limit confidence in the robustness of the credit claims.

Project Description

Red Flags

• ⚠12 material findings in the 2024 verification report, including missing flaring emission discount, use of 2006 IPCC Guidelines instead of the required 2019 Refinement, and missing monitored parameters
• ⚠4 Corrective Action Requests raised during verification, indicating systemic gaps in monitoring and reporting
• ⚠Leakage is described as 'quantified' in the justification but the actual deduction percentage is not stated in any available document
• ⚠Low extraction confidence across the document set, suggesting at least one key document was poorly readable or incomplete
• ⚠Contradiction between the verification report (FPIC conducted) and the monitoring report (FPIC not conducted) for the same reporting period
