AWMS Methane Recovery Project MX06-S-66, Durango, México

Audit Analysis

This 2007 CDM methane-recovery project from a Mexican cattle operation has a verified additionality case and uses a standardized methodology (AMS III.D.), but the available record contains no monitoring data, no leakage treatment, and no permanence mechanism. The complete absence of verified emission reductions and the 'not addressed' leakage status create meaningful uncertainty about whether the 111,508 tCO₂e lifetime claim is supported by actual project performance.

Project Description

Red Flags

• ⚠Leakage is explicitly 'not addressed' in the extracted record — a material gap for an animal-waste methane project where displaced or uncaptured CH₄ is a realistic pathway
• ⚠No monitoring reports or verified ERR figures are present in the available documents, making it impossible to confirm that any of the 111,508 tCO₂e claimed were actually delivered
• ⚠No buffer pool or permanence mechanism is documented, leaving the project without a safeguard against credit reversal if the capture system is decommissioned
• ⚠Two corrective action requests (crediting start date and weight-adjustment calculations) were raised during validation, indicating the initial PDD contained calculation errors
