Huaibin MSW Landfill Site LFG Recovery and Comprehensive Utilization Project

Audit Analysis

This VCS landfill gas recovery project (ACM0001 v19.0) has VVB-verified additionality and no permanence risk, and its verified emissions reductions align closely with the pro-rata lifetime expectation. However, the verification report identified 12 material findings and 12 corrective actions, and several critical parameters (grid emission factor, legally-required capture, additionality test type) show contradictions across documents, undermining confidence in the robustness of the credit claims.

Project Description

Red Flags

• ⚠12 material findings in the verification report, including inconsistent baseline emission calculations between the monitoring report and the ER sheet, and missing rationale for methane density assumptions
• ⚠Grid emission factor contradiction: the verification report uses 0.57205 (2019) while the monitoring report uses 0.8587 — a 50% discrepancy that directly affects credit quantities
• ⚠Contradiction on whether LFG capture is legally required: the verification report states true, the monitoring report states false — if legally required, additionality is fundamentally weakened
• ⚠12 corrective actions remain required, including cross-checking ER sheet and MR values, justifying methane density, and updating GWP values
• ⚠Minimum extraction confidence rated low, indicating at least one key document was poorly readable
