Audit Analysis
The Yangdong Landfill Gas Power Generation Project is a registered VCS LFG-to-energy project with a reputable VVB (Applus+) and a confirmed investment additionality test, but it carries six inter-document contradictions—including a critical dispute over whether gas capture is legally mandated—and four unresolved material findings. Verified emissions reductions for the two-year monitoring period (234,938 tCO₂e) represent roughly 91% of the pro-rata lifetime expectation, indicating conservative delivery. The project is functional but its data reliability is weakened by inconsistent reporting across the validation, monitoring, and verification documents.
Red Flags
- Contradiction on whether LFG capture is legally required: the verification report (Aug 2023) states true while the validation report (Apr 2023) states false; if legally mandated, additionality is materially undermined
- Grid emission factor differs by 58% between the validation report (0.50885) and the verification report (0.8042, 2019), directly affecting credit volume
- Four material findings remain, including a monitoring plan that does not meet ACM0001 requirements (CAR 01) and missing parameter FCH4,BL,R,y in ex-ante estimations
- Leakage justification is inconsistent: the verification report calls it 'quantified' while the monitoring report calls it 'deemed negligible', yet the deduction is 0% in both cases
- Gas capture legally mandated — additionality in doubt
