Audit Analysis

Wakefield Biochar Facility 1 is a Puro.earth biochar removal credit with a named VVB and a clean verification report (no material findings), but critical permanence and leakage data are absent from the extracted record. The project-specific baseline and missing buffer pool information create meaningful uncertainty for a removal credit, and the absence of both claimed and verified ERR figures limits any over- or under-delivery assessment.

Red Flags

  • No buffer pool percentage or permanence mechanism stated for a removal credit — reversal risk is unaddressed in the available record
  • Leakage deduction and justification are entirely absent from the extracted documents, which is unusual for a biochar project where feedstock sourcing and land-use change can generate leakage
  • Both claimed and verified ERR figures are missing, preventing any assessment of whether the project is over- or under-delivering relative to its ex-ante estimate
  • Permanence claim not stated in available documents
