El Molle – Landfill gas (LFG) capture project

Audit Analysis

The El Molle LFG capture project has a VVB-confirmed investment additionality test and a project-specific baseline reassessed in 2021, but the validation report identified six material findings and two corrective actions related to emission factor calculations, waste composition evidence, and QA/QC transparency. No buffer pool, permanence mechanism, or monitoring data is documented, and the ERR figures differ substantially between the PDD and the validation report (likely reflecting different reporting periods). Overall, the project shows moderate methodological soundness with notable documentation and verification gaps.

Project Description

Red Flags

• ⚠Six material findings (CL 01–CL 06) and two corrective actions (CAR 01–CAR 02) in the validation report, including an incorrect operating-margin emission factor calculation and inconsistent MAP/PET parameters
• ⚠ERR discrepancy: PDD reports 1,046,273 tCO₂e while the validation report confirms 149,468 tCO₂e — a roughly 7× difference that, while likely reflecting a full-crediting-period vs. annual basis, is not explicitly reconciled in the available documents
• ⚠No buffer pool, permanence mechanism, or reversal-event data is documented for this 7-year crediting period
• ⚠Leakage treatment is contradictory: the validation report deems leakage negligible (0% deduction) while another source references a 'quantified' approach
• ⚠Low extraction confidence in the document analysis, with one of four source documents identified only as 'unknown'
