Heyuan Dengta Landfill Gas Power Generation Project

Audit Analysis

A landfill gas power generation project under the well-established ACM0001 methodology with VVB-confirmed additionality, but undermined by three inter-document contradictions (leakage treatment, legal capture requirement, crediting period), a material finding on the monitoring plan, and low extraction confidence across the document set. The project type is inherently low-risk for permanence, yet the absence of a stated buffer pool, monitoring period, and usage-rate data leaves meaningful evidence gaps.

Project Description

Red Flags

• ⚠Contradiction between PDD and validation report on whether landfill gas capture is legally required (PDD: yes; validation report: no) — if capture is mandated, additionality is compromised
• ⚠Contradiction on leakage treatment: PDD (2023) states leakage was quantified, while the validation report (2024) records it as merely 'deemed negligible' with a 0% deduction
• ⚠Material finding in the validation report: the monitoring plan did not meet ACM0001 requirements (corrected, but indicates initial MRV weakness)
• ⚠Minimum extraction confidence rated 'low' across the document set, reducing reliability of all extracted figures
• ⚠Total ERR claimed and verified are identical (977,106 tCO₂e) with no stated monitoring period, making independent verification of the figure impossible to confirm
