AWMS Methane Recovery Project MX06-S-69, Chihuahua, México

Audit Analysis

This 2007 CDM methane-avoidance project (biodigester on animal waste in Chihuahua, Mexico) has a properly verified additionality assessment and a reputable VVB, but the available record is limited to the validation stage with no monitoring reports or verified emission reductions. Leakage is explicitly not addressed in the project design, which is a material gap for a methane-capture project, and the baseline is project-specific and modeled without any reassessment data.

Project Description

Red Flags

• ⚠Leakage is marked as 'not addressed' in the project design — a significant omission for a biodigester methane-capture project where methane slip is a realistic risk
• ⚠No monitoring reports or verified emission reductions are available in the extracted record; the 130,723 tCO₂e claim over the 10-year crediting period is entirely ex-ante and unverified
• ⚠Seven corrective actions were required during validation (biodigester design, baseline exclusion of specific corrals, bundling distances, emission factor updates), indicating the initial PDD had substantive design gaps
• ⚠No buffer pool, no LCA, and no feedstock sustainability assessment are present in the record
