QUATÁ LANDFILL GAS PROJECT

Audit Analysis

The QUATÁ Landfill Gas Project is a VCS-registered LFG destruction project with a solid additionality case (investment test confirmed by Applus+ Certification) and a reasonable permanence argument based on methane destruction. However, a significant grid emission factor discrepancy between the PDD (0.2252 tCO₂e/MWh) and the validation report (1.3 tCO₂e/MWh) raises baseline validity concerns, and the project-specific modeled baseline adds uncertainty. Documentation quality was flagged by four corrective action requests (all resolved), and the low extraction confidence across nine source documents limits assurance.

Project Description

Red Flags

• ⚠Grid emission factor differs by a factor of ~5.8 between the PDD (0.2252) and the validation report (1.3 tCO₂e/MWh), creating material uncertainty in the energy-displacement component of the credit calculation
• ⚠The PDD originally claimed 726,115 tCO₂e while the validation report validated 598,117 tCO₂e — a 17.6% reduction that, combined with the grid EF discrepancy, suggests parameter inconsistencies across documents
• ⚠Leakage deduction is 0% with only a 'deemed negligible' justification; no quantified leakage analysis is documented
• ⚠Minimum extraction confidence across the nine source documents is rated low, reducing assurance in the extracted data
