Hongya MSW landfill site biogas power generation project

Audit Analysis

The Hongya MSW landfill biogas project is a registered VCS project with VVB-confirmed additionality and reasonable credit delivery (~84% of pro-rata expectation), but is undermined by four material findings (inconsistent dates and FCH4 values across documents), a 0% leakage deduction with contradictory justifications, and an unresolved contradiction on whether methane capture is legally required. No buffer pool or permanence mechanism is documented, and several monitoring parameters remain unreported.

Project Description

Red Flags

• ⚠Four material findings in the 2026 verification report, including inconsistent FCH4,BL,y values across the monitoring report, verification report, and ER spreadsheet, indicating data quality issues in the credit calculation
• ⚠Contradiction on whether methane capture is legally required: the 2026 monitoring report states it is not, while an earlier monitoring report states it is — if legally required, additionality is compromised
• ⚠Leakage deduction of 0% with inconsistent justification: the 2022 verification report records it as 'not addressed' while the 2026 monitoring report claims it is 'deemed negligible' without quantification
