Cogeneration of power and steam from Bioener S.A´s forestry waste

Audit Analysis

A CDM biomass cogeneration project in Uruguay with VVB-confirmed additionality but significant data reliability issues, including a seven-fold discrepancy in claimed emissions reductions between the PDD and validation report, a grid emission factor contradiction, and a baseline method conflict. No monitoring or verification reports are available, and the project's crediting period (2011–2018) has long expired, leaving no verified performance data to assess.

Project Description

Red Flags

• ⚠Total ERR claimed differs by a factor of seven between the PDD (350,360 tCO₂e) and the validation report (50,051 tCO₂e), raising serious over-crediting concerns in the PDD
• ⚠Grid emission factor contradicts between the PDD (0.655 tCO₂/MWh) and an appendix (0.733 tCO₂/MWh), directly affecting the baseline calculation
• ⚠Baseline method is stated as 'project-specific' in the validation report but 'jurisdictional' in the PDD — a fundamental methodological conflict
• ⚠No buffer pool, no reversal-event data, and no permanence mechanism documented for a 7-year crediting period
• ⚠No monitoring reports or verified ERR figures are available in the extracted record; the project's entire performance history is unverifiable
