AWMS Methane Recovery Project MX06-S-54, Sonora, México

Audit Analysis

This CDM methane recovery project (AWMS, Sonora, Mexico) has a VVB-confirmed barrier additionality test and uses the standardized AMS III.D. methodology, but the record is heavily weighted toward the 2007 validation stage with no monitoring reports or verified emission figures available. The validation report flagged 19 material findings and 13 corrective actions covering emission calculation errors, methodology compliance gaps, and technical omissions, indicating a weak initial PDD. The absence of any permanence mechanism (buffer pool), quantified leakage treatment, or post-validation monitoring data leaves significant uncertainty about the project's actual performance and credit integrity.

Project Description

Red Flags

• ⚠No buffer pool or permanence mechanism identified for a methane avoidance project, leaving reversal risk unaddressed
• ⚠19 material findings and 13 corrective actions in the validation report, including errors in baseline emission calculations, missing CO2 emissions from electricity, and incorrect methodology version references
• ⚠No monitoring reports or verified emission reduction figures found in the extracted record — the 65,175 tCO2e claimed figure is unverified
• ⚠Leakage is only 'deemed negligible' with no quantified deduction or detailed justification in the available documents
