Hexian MSW Landfill Site LFG recovery to power project

Audit Analysis

The Hexian LFG-to-power project is a registered VCS project with a reputable VVB (Applus+) and a standard AMS methodology, but it carries significant integrity concerns: the verification report states that LFG capture is legally required (undermining additionality), three material findings and five corrective actions remain open, and multiple contradictions exist across documents on FPIC, leakage justification, and the grid emission factor. The project delivered roughly 106% of its pro-rata ex-ante expectation for the elapsed monitoring period, so over-crediting is not evident, but the data-reliability issues and low extraction confidence temper confidence in the underlying figures.

Project Description

Red Flags

• ⚠Verification report (2025) states LFG capture is legally required, directly undermining the additionality claim; the PDD (2023) states the opposite — a fundamental contradiction on a core eligibility criterion.
• ⚠Three material findings remain open, including missing grievance-redressal documentation, absent flow-meter and gas-analyser specifications in the monitoring report, and unverified government-approval evidence.
• ⚠Grid emission factor differs by ~33% between the verification report (0.7921, 2019) and the monitoring report (0.58955), raising questions about which value was actually used in the credit calculation.
• ⚠Five corrective actions are still required by the VVB, indicating the verification was not fully clean.
• ⚠Minimum extraction confidence is rated low, meaning at least one key document was poorly readable, reducing reliability of the extracted data.
