Liling LFG Power Generation Project

Audit Analysis

The Liling LFG Power Generation Project is a landfill gas-to-energy project with a solid additionality assessment (combined test, VVB-confirmed) and no permanence risk since the gas is consumed rather than stored. However, three material findings in the verification report—including an incorrect methane GWP value and a monitoring-period inconsistency—signal quality-control weaknesses, and contradictions between the 2021 verification and 2024 monitoring reports on leakage treatment and baseline characterisation reduce confidence in the data record.

Project Description

Red Flags

• ⚠The verification report (2021) recorded the GWP of CH4 as 21 or 25 instead of the correct 28 tCO2e/tCH4, a fundamental calculation error that required corrective action
• ⚠The monitoring period stated in the ER and Joint PD&MR (Version 1.0) was inconsistent with the public comment version, indicating a documentation control failure
• ⚠Leakage justification is contradictory: the 2021 verification report states 'deemed negligible' while the 2024 monitoring report states 'quantified', leaving the actual treatment ambiguous
• ⚠Three material findings required corrective actions, indicating the project documentation did not meet VCS quality standards at the time of verification
