GHG emissions reductions from improved industrial wastewater treatment in Embaré – Lagoa da Prata, Minas Gerais, Brazil

Audit Analysis

A CDM methane-avoidance project from industrial wastewater treatment in Brazil with VVB-confirmed additionality, but undermined by four material findings at validation, four cross-document contradictions (including a 1,000× grid emission factor discrepancy), and a complete absence of monitoring or verified-credit data. The project's integrity rests on a project-specific baseline with mixed measured and modeled inputs, and no buffer pool or permanence safeguards are documented.

Project Description

Red Flags

• ⚠Grid emission factor differs by a factor of 1,000 between the PDD (0.0003112) and an appendix (0.3111875), indicating a unit or transcription error that could distort the baseline calculation
• ⚠Four corrective actions were required at validation, including non-compliant grid EF documentation, incomplete sensitivity analysis, questioned applicability of the Combined additionality tool, and insufficient baseline data under AMS-III.H v16
• ⚠No monitoring reports, verified ERR figures, or monitoring period data were found in any available document
• ⚠Leakage treatment is contradictory: the validation report states it was deemed negligible (0% deduction) while an appendix describes it as quantified
