Audit Analysis

The Carboneers & Terrafront biochar project presents a technically credible carbon removal approach using renewable energy and documented feedstock sustainability, with a low reversal risk profile consistent with biochar's recalcitrant nature. However, the project suffers from a critical lack of independent verification: no VVB is identified, no ERR figures are available, and the 1000-year permanence claim is not backed by a buffer pool. The documentation base is thin (PDD and stakeholder consultation only) with low extraction confidence, limiting confidence in the overall credit quality.

Red Flags

  • 1000-year permanence claim with no buffer pool or permanence risk mitigation mechanism identified in available documents
  • No VVB identified and additionality verification status not confirmed in any available document
  • No ex-ante or verified ERR figures found in the extracted record, making over- or under-crediting impossible to assess
  • Only two documents available (PDD and stakeholder consultation) with low extraction confidence; no verification report or monitoring report present
