VCS Development Project of Methane Emission Reduction in Dairy Farming in Yongchang Pasture
#778of 1084 in China#891of 1339 in Verra (VCS)#46of 105 in AMS-III.D
Audit Analysis
A VCS-registered dairy methane reduction project in China using the standardized AMS III.D methodology, with VVB-confirmed additionality and appropriate non-permanence treatment for an avoidance project. However, the project-specific modeled baseline, thin leakage justification, three outstanding corrective actions, and the absence of any monitoring or verification data limit confidence in the claimed 479,550 tCO2e lifetime reduction.
Red Flags
- Three corrective actions remain open, including missing monitoring parameters (BGburnt,y, wCH4, TEG,m, FRG,m, SPECflare, Flamem) in the PD and an outdated Tool 14 reference
- ERR increased by approximately 21% between PDD versions (397,080 in Sept 2024 to 479,550 in Aug 2025) without a clear explanation in the extracted record
- Leakage deduction of 0% justified only as 'deemed negligible' without quantified analysis, which is thin for a dairy manure management project where displaced emissions are plausible
- No monitoring or verification report data available; total verified ERR is not stated in the extracted record
- Low extraction confidence across the document set, indicating at least one key document was poorly readable
