Huojia County Second MSW Landfill Site LFG Pollution Treatment and Comprehensive Utilization Project
#461of 1084 in China#533of 1339 in Verra (VCS)#12of 34 in AMS-III.G
Audit Analysis
A VCS-registered landfill gas capture and energy-use project in China with VVB-confirmed additionality and no reversal risk, but undermined by a legally required capture obligation, inconsistent leakage and baseline characterisations across documents, and a verified output of only ~47% of the pro-rata PDD expectation. Multiple data contradictions and missing usage-monitoring details limit confidence in the credit figures.
Red Flags
- LFG capture is stated as legally required in the verification report, which directly challenges the additionality premise even though the VVB confirmed a combined test
- Verified ERR of 31,250 tCO2e is only ~47% of the pro-rata PDD expectation (~66,900 tCO2e for the 2.6-year monitoring window), raising questions about the accuracy of the ex-ante estimate
- Grid emission factor differs by 33% between the verification report (0.8587) and the monitoring report (0.57205), with no documented explanation for the change
- Leakage justification is inconsistent: the verification report states it was 'quantified' while the monitoring report simply 'deems it negligible', yet both apply a 0% deduction
