AWMS Methane Recovery Project, Ampuero Dairy Farm

Audit Analysis

A small-scale CDM methane avoidance project at a Mexican dairy farm with a VVB-verified investment additionality test and an appropriate simplified methodology (AMS III.D). However, the project record is thin: no monitoring or verification reports were found, the extraction confidence is low, and a tenfold discrepancy in the claimed ERR between the PDD and the validation report raises data-reliability concerns. The project-specific modeled baseline and a 0% leakage deduction justified only as 'deemed negligible' leave moderate residual risk.

Project Description

Red Flags

• ⚠Tenfold discrepancy in total ERR: the PDD (Aug 2008) states 83,850 tCO2e while the validation report (Apr 2009) states 8,385 tCO2e — a 10× difference that undermines confidence in the project's quantification record
• ⚠No monitoring reports or verification reports found in the extracted record; the project's crediting period ended in August 2019 with no evidence of periodic monitoring
• ⚠Leakage deduction of 0% justified only as 'deemed negligible' with no quantified analysis, which is weak for a methane-avoidance project where displaced emissions are plausible
• ⚠Low extraction confidence across the document set, meaning key data may be missing or misread
