Huangping Aonong Swine Farm Composting Project

Audit Analysis

A VCS-registered swine farm waste management project (AMS-III.D) with VVB-confirmed additionality and no inherent reversal risk, but hampered by a mid-project technology change from composting to anaerobic digestion, a public comment on potential baseline double-counting, and the absence of any monitoring data or buffer pool specification. The project is at an early stage with only a validation report available, and low extraction confidence limits the depth of assessment.

Project Description

Red Flags

• ⚠Technology changed from aerobic composting to anaerobic digestion after initial PDD, requiring a full methodology switch to AMS-III.D and PD revision — raises questions about project design stability
• ⚠Public comment raised concern that baseline emissions from wastewater and biomass residue waste were double-counted or overestimated; the project proponent clarified this was not the case and the ER calculation was revised, but the initial error signals weak baseline rigour
• ⚠No monitoring report or monitoring period is available; the claimed and verified ERR figures are identical (510,200), indicating no actual field monitoring has yet been reported
