AWMS Methane Recovery Project BR06-S-26, Minas Gerais, Brazil

Audit Analysis

A CDM methane-recovery project from Brazilian animal waste management with VVB-confirmed additionality and no reversal events, but hampered by a significant under-delivery (roughly 45% of pro-rata expectation), contradictory leakage treatment across documents, and a project-specific modeled baseline with no reassessment data. The project is conservative in its actual credit delivery, reducing over-crediting risk, but the documentation record is limited to the first two years of a ten-year crediting period.

Project Description

Red Flags

• ⚠Verified ERR figure is not stated in any available document; only the claimed 13,035 tCO₂e for the 2008–2010 monitoring period is available, making independent verification of actual delivery impossible from the extracted record.
• ⚠Leakage treatment is contradictory: the monitoring report (2010) records leakage as 'not addressed' while the validation report (2011) states it was 'deemed negligible' — the inconsistency undermines confidence in the leakage assessment.
• ⚠The project delivered only ~45% of the pro-rata expectation for the elapsed monitoring period (13,035 vs ~28,900 tCO₂e expected), suggesting operational or baseline-accuracy issues that were not fully resolved.
• ⚠Baseline data for Fazenda Ponte Alta I and II in the PDD did not match on-site data and had to be corrected to more conservative values, indicating initial baseline inaccuracy.
