Cartagena Landfill Gas Capture and Usage Project

Audit Analysis

The Cartagena Landfill Gas project has a VVB-confirmed additionality assessment and documented safeguards, but is undermined by ten material findings in the validation report, a project-specific modeled baseline, and a complete absence of leakage treatment in a project type where atmospheric escape is a realistic risk. No monitoring reports or verified emission figures are available, leaving the claimed 996,687 tCO₂e lifetime estimate unverified against actual performance.

Project Description

Red Flags

• ⚠Leakage is explicitly not addressed in a landfill gas capture project where uncollected methane escaping to the atmosphere is a well-known risk pathway
• ⚠Ten material findings in the validation report, including discrepancies in historic waste volumes, waste composition data, and parameter type errors for 2018–2020, raise concerns about the reliability of the ex-ante emission estimates
• ⚠No monitoring reports or verified emission reduction figures are available in the extracted record, so the 996,687 tCO₂e claimed figure cannot be cross-checked against actual performance
• ⚠Contradiction within the same validation report: additionality test described as both 'investment' and 'combined'
