Energia Verde Carbonization Project - Mitigation of Methane Emissions in the Charcoal Production of Grupo Queiroz Galvão, Maranhão, Brazil

Audit Analysis

A CDM methane-capture project in Brazil's charcoal sector with VVB-confirmed additionality and no reversal events, but the first monitoring period delivered only about 36% of the pro-rata expected reductions, raising significant over-crediting concerns. The project-specific modeled baseline and a 0% leakage deduction with a 'deemed negligible' justification (contradicting the PDD's 'quantified' treatment) weaken the integrity case. Documentation is reasonably complete with high extraction confidence, but only one monitoring period is available.

Project Description

Red Flags

• ⚠First monitoring period delivered only 80,771 tCO2e against a pro-rata expectation of ~226,845 tCO2e (35.6% of expected), indicating substantial under-delivery or over-estimation in the PDD
• ⚠Leakage treatment contradicts between the PDD (quantified) and the monitoring report (deemed negligible) with a 0% deduction applied
• ⚠Baseline methodology is inconsistent between the validation report (measured) and the monitoring report (modeled), and is project-specific rather than jurisdictional
• ⚠47 Corrective Action Requests were raised during validation, suggesting significant initial design issues (all subsequently closed)
