LIANZHOU LANDFILL GAS POWER GENERATION PROJECT

Audit Analysis

The Lianzhou Landfill Gas Power Generation Project is a VCS-registered avoidance project under ACM0001 with VVB-confirmed additionality, but it carries significant data contradictions across key parameters (grid emission factor, baseline type, legal capture requirement) and four material findings that required corrective action. The project delivered approximately 84% of its pro-rata ex-ante expectation for the elapsed monitoring period, indicating no over-crediting, yet the unresolved discrepancies between the validation and verification reports undermine confidence in the robustness of the underlying claims.

Project Description

Red Flags

• ⚠Contradiction between validation report (capture not legally required) and verification report (capture legally required) directly undermines the additionality claim; the verification report (2023-08-01) is privileged as more recent, but the legal requirement under GB 50869-2013 was flagged as a material finding requiring further justification
• ⚠Grid emission factor differs by 58% between the validation report (0.50885) and the verification report (0.8042), a discrepancy that materially affects the credit calculation and is not explained in the extracted record
• ⚠Four material findings in the verification report, including non-compliance of the monitoring plan with ACM0001 and incomplete no-net-harm control measures, indicate initial documentation gaps that were only remediated through corrective actions
• ⚠Baseline characterisation is contradictory: the verification report describes it as 'measured' while the validation report describes it as 'modeled', and no baseline reassessment date is recorded
• ⚠Gas capture legally mandated — additionality in doubt
