Puyang County Rural MSW Landfill Site LFG Pollution Treatment and Comprehensive Utilization Project

Audit Analysis

This VCS landfill gas recovery project in China has a VVB-verified additionality assessment and low permanence risk, but is undermined by a serious contradiction over whether LFG capture is legally required, 13 material findings in the verification report, and a grid emission factor discrepancy between the monitoring and verification reports. The project delivered roughly 63% of its pro-rata ex-ante expectation for the elapsed monitoring period, which is conservative, but the documentation quality and data consistency issues limit confidence in the overall credit claims.

Project Description

Red Flags

• ⚠Contradiction on whether LFG capture is legally required: the verification report (Jan 2024) states it is, while the validation report (Jan 2023) states it is not — if legally mandated, the additionality claim is fundamentally weakened
• ⚠Grid emission factor discrepancy: the verification report uses 0.8587 tCO₂e/MWh while the monitoring report uses 0.57205 tCO₂e/MWh, a 50% difference that directly affects credit quantities
• ⚠13 material findings and 9 corrective actions identified in the verification report, including missing baseline data sources, missing calculation equations, and inconsistent parameter descriptions
• ⚠FPIC status contradicted between the PDD (not conducted) and the validation report (conducted), raising questions about the reliability of social safeguards documentation
• ⚠Leakage justification is inconsistent: the verification report describes it as 'quantified' while the monitoring report calls it 'deemed negligible', both resulting in a 0% deduction
