AWMS Methane Recovery Project BR06-S-25, Minas Gerais, Brazil

Audit Analysis

A CDM methane recovery project in Minas Gerais with confirmed additionality (combined test, DNB-verified) and a standardized methodology (AMS III.D v11), but significant gaps in leakage treatment, a project-specific modeled baseline, and a large unexplained discrepancy between claimed and verified emissions reductions that raises data-reliability concerns. The project carries moderate over-crediting risk due to the leakage gap and baseline conservatism questions flagged during validation.

Project Description

Red Flags

• ⚠Leakage is explicitly not addressed in the available documents, with no deduction or justification stated — a material gap for a methane capture project
• ⚠Verified ERR (282,217 tCO2e) is approximately 20× the claimed ERR (14,230 tCO2e) for the monitoring period, indicating either a severe ex-ante underestimation or a data/unit error that undermines confidence in the credit quantity
• ⚠17 material findings (CARs and CRs) during validation raised questions about baseline calculation, solid separator treatment, and project emissions monitoring, with 5 corrective actions required before registration
• ⚠CORSIA eligibility and CCP status are not stated in any available document, leaving dual-channel risk unassessed
