Panzhou County Chicken Farm Manure Composting Project

Audit Analysis

A VCS-registered chicken manure composting project in China using the simplified AMS-III.F methodology, with VVB-confirmed combined additionality and no material findings. However, the project-specific modeled baseline, absence of a stated buffer pool, a 0% leakage deduction with contradictory justifications across monitoring reports, and a significant grid emission factor discrepancy (0.486 vs 0.774) introduce moderate over-crediting and data-reliability concerns.

Project Description

Red Flags

• ⚠Grid emission factor contradiction: the 2024-10-24 monitoring report uses 0.7738 tCO2e/MWh while the 2025-03-15 monitoring report uses 0.48595 tCO2e/MWh — a 37% difference that materially affects the avoidance calculation
• ⚠Leakage justification shifted from 'quantified' (monitoring report, 2024-11-12) to 'deemed negligible' (monitoring report, 2025-03-15) with a 0% deduction, raising questions about whether leakage was actually assessed
• ⚠No buffer pool percentage or permanence claim is stated in any available document, leaving reversal risk unquantified for a 10-year crediting period
• ⚠FNRB value, FNRB method, usage monitoring method, and carbon content testing are all absent from the extracted record, limiting independent verification of the 37,793 tCO2e claim
