Xinjiang Muge Swine Farm Manure Management System GHG Mitigation Project

Audit Analysis

A VCS-registered swine manure management project (ACM0010) in Xinjiang, China, with VVB-confirmed additionality and quantified leakage, but a project-specific modeled baseline and multiple material findings in the verification report. The project delivered only about 26% of its pro-rata ex-ante expectation for the elapsed monitoring period, indicating conservative crediting. Low extraction confidence and several unquantified parameters (FNRB, usage monitoring, CORSIA/CCP status) limit the depth of assurance.

Project Description

Red Flags

• ⚠The PDD (Nov 2022) states a lifetime ex-ante estimate of 2,908,811 tCO2e, while the verification report (Nov 2025) states 1,158,920 tCO2e — a 60% reduction that is not explained in the extracted record.
• ⚠Five corrective actions were raised in the verification report (SDG indicator alignment, default methane density, calibration schedule discrepancy, methane destruction data, government authorization evidence), indicating material gaps in the project's monitoring and documentation.
• ⚠FNRB value, usage monitoring method, and CORSIA/CCP eligibility are all not stated in the available documents, leaving key claim-safety parameters unverified.
• ⚠Min extraction confidence is rated low, meaning at least one key document was poorly readable, reducing assurance in the extracted data.
