Yangchun Landfill Gas Power Generation Project

Audit Analysis

The Yangchun Landfill Gas Power Generation Project is a registered VCS project under the well-established ACM0001 methodology with a reputable VVB (Applus+), but it carries moderate data-reliability concerns stemming from five inter-document contradictions, five material findings at validation, a thin leakage justification, and a low extraction confidence rating. The project delivered roughly 92% of its pro-rata ex-ante expectation for the elapsed monitoring period, which is a reasonable and slightly conservative outcome. Overall, the project is functional but sits in the lower-middle quality band due to documentation gaps and unresolved discrepancies.

Project Description

Red Flags

• ⚠Contradiction between the PDD (capture legally required = true) and the validation report (capture legally required = false) directly undermines the additionality claim; the validation report (2023-04-24) is privileged as the more recent VVB assessment, but the PDD statement raises a residual risk that the project may not be additional.
• ⚠Five material findings at validation, including the monitoring plan not meeting ACM0001 requirements, incomplete no-net-harm controls, and a missing baseline parameter (FCH4,BL,R,y), indicate significant documentation gaps at the time of validation.
• ⚠Leakage deduction of 0% is justified only as 'deemed negligible' with no quantified analysis, which is thin for a landfill gas collection system where gas escape is a realistic risk.
• ⚠No buffer pool percentage is stated in any available document, leaving permanence risk unquantified despite the 'not applicable' reversal statement.
• ⚠Minimum extraction confidence is rated low, meaning at least one key document was poorly readable, reducing confidence in the extracted data.
