BRASCARBON Methane Recovery Project BCA-BRA-05, Brazil

Audit Analysis

A CDM anaerobic-digestion methane-avoidance project in Brazil with an investment additionality test and no legally mandated capture, but weakened by a project-specific modeled baseline, absence of a buffer pool, and six outstanding corrective actions from the verification body. The project over-delivered relative to its pro-rata expectation (≈173%), which is reassuring, yet the thin leakage justification and multiple material findings (including a sampling-plan inconsistency) leave meaningful uncertainty about the robustness of the credit claims.

Project Description

Red Flags

• ⚠Six corrective actions remain open, including missing monitoring parameters in the PDD and a missing baseline-validity assessment per Methodological Tool 03.0.1
• ⚠No buffer pool or reversal-risk mitigation is stated in the extracted record for a methane-avoidance project where digester shutdown would release stored methane
• ⚠Leakage deduction is 0% with only the label 'quantified' as justification; no explicit quantification or negligible-impact rationale is provided in the available documents
• ⚠Material finding CL-3 flags a sampling-plan confidence-level inconsistency (95% vs 90/10), undermining confidence in the monitoring data quality
• ⚠FAR-1 records a 76-day delay in the renewal-intention notification beyond the 180-day window, indicating procedural non-compliance
