AWMS Methane Recovery Project BR06-S-33, Minas Gerais and Sao Paulo, Brazil

Audit Analysis

This 2007 CDM methane-recovery project in Brazil has a VVB-confirmed additionality assessment and a reputable verifier (TÜV SÜD), but the available record is limited to the PDD and validation report with no monitoring data whatsoever. A seven-fold discrepancy in claimed emission reductions between the PDD and the validation report, combined with an unquantified 'negligible' leakage claim and the absence of any permanence safeguard, leaves significant uncertainty about the project's actual credit integrity.

Project Description

Red Flags

• ⚠Seven-fold discrepancy in total ERR: the PDD (Nov 2007) states 67,034 tCO₂e while the validation report (Nov 2007) states 9,576 tCO₂e; the VVB figure is privileged as the later, authoritative assessment, but the gap signals weak initial PDD quality
• ⚠No monitoring reports or verified ERR figures are present in the extracted record, so actual performance over the 2007–2014 crediting period is entirely unverified
• ⚠Leakage is designated 'negligible' with no quantified deduction or supporting calculation, which is a weak basis for a methane-recovery project where fugitive emissions are a realistic risk
• ⚠No buffer pool, reversal-risk mechanism, or permanence safeguard is documented for a project whose credits depend on continued operation of biogas capture infrastructure
