Nanning Landfill Gas Power Generation Project

Audit Analysis

The Nanning Landfill Gas Power Generation Project has a sound fundamental design with VVB-confirmed additionality and no reversal events, but the verification report identified seven material findings and nine corrective actions related to data gaps, calculation transparency, and calibration deficiencies. The project delivered only about 52% of its pro-rata ex-ante expectation for the 18-month monitoring period, and leakage was not properly addressed in the verification report. Overall, the project is functional but carries meaningful MRV quality and documentation risks.

Project Description

Red Flags

• ⚠Seven material findings in the 2025 verification report, including missing hourly data records, lack of transparency in emission reduction calculations, and absence of recent calibration certificates for monitoring equipment
• ⚠Nine corrective actions required, spanning data substitution methods, calculation traceability, methane destruction evidence, and incomplete monitoring plan procedures
• ⚠Leakage deduction of 0% with justification recorded as 'not addressed' in the verification report, while the monitoring report claims it was 'deemed negligible' — an unresolved inconsistency
• ⚠FPIC status contradicts between the verification report (conducted) and the monitoring report (not conducted), creating uncertainty on free, prior, and informed consent
