Gansu Hui County Muge Swine Farm Manure Management System GHG Mitigation Project
#168of 1084 in China#221of 1339 in Verra (VCS)#5of 66 in ACM0010
Audit Analysis
A VCS-registered biogas project from swine manure in Gansu, China, with a VVB-confirmed investment additionality test and a consistent first-period verification of 58,604 tCO₂e. Key gaps include unaddressed reversal risk, an unstated buffer pool percentage, and a project-specific modeled baseline, which collectively moderate the integrity and claim-safety scores. No over-crediting is evident, as the verified figure represents roughly 82% of the pro-rata lifetime expectation for the elapsed monitoring period.
Red Flags
- Reversal events are marked as 'not addressed' in the verification record, leaving permanence risk for the biogas system unquantified
- FPIC (Free, Prior and Informed Consent) is not documented as conducted, despite the project operating in a Hui ethnic minority county
- Leakage is described as 'quantified' in the justification, yet the actual deduction percentage is absent from the extracted record
