Shangcai Chenfazhai Biogas Recovery and Utilization Project

Audit Analysis

A registered VCS biogas project in China with a combined additionality test and a project-specific modeled baseline, but the verification report identified 14 material findings and 13 corrective actions, indicating significant gaps in MRV documentation and calculation rigor. The VVB verified emissions reductions at 87.2% of the project's own claim, and several key parameters (leakage percentage, FNRB, usage rates, buffer pool) are absent from the extracted record. Free, Prior and Informed Consent was not conducted, and the low extraction confidence further undermines confidence in the available evidence.

Project Description

Red Flags

• ⚠14 material findings and 13 corrective actions identified by the VVB, including missing equations, missing monitored parameters, missing ER/IRR spreadsheets, and an unvalidated 90% boiler efficiency assumption
• ⚠Free, Prior and Informed Consent (FPIC) was not conducted despite the project affecting local communities in China
• ⚠Leakage justification is described as 'quantified' but no actual deduction percentage appears in any extracted document
• ⚠Additionality verification by the VVB is not confirmed in the extracted record (field not stated)
• ⚠Low extraction confidence across the document set, meaning at least one key document was poorly readable and data may be incomplete
