AWMS Methane Recovery Project MX06-S-92, Sonora, México

Audit Analysis

This 2007 CDM methane-avoidance project (AWMS) in Sonora, Mexico has a VVB-confirmed barrier additionality test and a well-known VVB (TÜV SÜD), but the available record is limited to the initial validation report and PDD with no monitoring reports or verified emissions data. Ten material findings were identified during validation (including missing CO₂ emissions and incorrect site data), and the project-specific modeled baseline, unquantified 'negligible' leakage claim, and absence of a buffer pool introduce moderate integrity and claim-safety concerns.

Project Description

Red Flags

• ⚠Ten material findings in the validation report, including initially missing CO₂ emissions from electricity use and incorrect GPS coordinates for three sites, indicate significant data-quality issues at project inception
• ⚠No buffer pool or permanence mechanism is documented, and no reversal-event data is available for this methane-avoidance project
• ⚠Leakage is 'deemed negligible' in the validation report but was not addressed at all in the PDD, and no quantitative deduction or justification is provided
• ⚠No monitoring reports or verified ERR figures are available in the extracted record, making it impossible to confirm actual performance against the 118,035 tCO₂e lifetime claim
