Audit Analysis

The Euthenia Energy Center is a Spanish biochar project verified under the Puro standard with a named VVB (Normec Verifavia SAS) and a confirmed combined additionality test. However, critical permanence and leakage parameters are absent from the extracted record, the plant was not operational during the verification visit, and a corrective action was issued regarding tracking of biochar sold for non-eligible activities. The project shows moderate quality with notable gaps in biochar-specific risk management.

Red Flags

  • The plant was not operational during the verification visit, so live observation of the biochar production process was not possible (material finding, verification report 2024-12-19).
  • No buffer pool, permanence mechanism, or permanence claim period is stated in the extracted record — a significant gap for a biochar project where carbon loss through weathering or erosion is a real risk.
  • No leakage deduction or leakage justification is stated, and a corrective action was issued recommending a more detailed tracking system for biochar sold for non-eligible activities, suggesting potential leakage or double-use risk.
  • The project uses a project-specific baseline rather than a jurisdictional or standardised one, increasing the risk of baseline over-crediting.
  • Permanence claim not stated in available documents
