AWMS Methane Recovery Project MX06-S-91, Nuevo Leon, México

Audit Analysis

This CDM methane avoidance project (2007–2014) has a VVB-confirmed barrier additionality test and a well-known verification body (TÜV SÜD), but suffers from significant evidence gaps: no monitoring data, no verified emission reductions, no buffer pool, and leakage was never addressed. Five material findings during validation indicate initial documentation weaknesses, and the project-specific modeled baseline limits confidence in the 84,031 tCO₂e lifetime claim.

Project Description

Red Flags

• ⚠Leakage was explicitly not addressed in a methane avoidance project where fugitive emissions and displaced-waste pathways are expected
• ⚠No buffer pool or permanence mechanism documented for a project whose crediting period has already expired (2014)
• ⚠No monitoring reports or verified emission reduction figures available in the extracted record
• ⚠Five material findings (corrective action requests) were raised during validation, including missing biodigester design and outdated emission factors
• ⚠Baseline is project-specific and modeled rather than jurisdictional, with no reassessment data available
