Audit Analysis

Carbonity's biochar project in Canada has a VVB-confirmed investment additionality test and a recent verification, but critical permanence and leakage elements are absent from the available record. The project-specific baseline and the lack of a stated buffer pool or leakage treatment create meaningful uncertainty for a carbon-removal credit. Documentation is limited to two sources, and the absence of a claimed ERR figure prevents any over-crediting check.

Red Flags

  • No buffer pool or permanence mechanism is stated in the available documents for a biochar removal project, leaving reversal risk unaddressed
  • Leakage is neither quantified nor justified in any available document, despite being a material consideration for biochar feedstock sourcing
  • Total ERR claimed is not available, making it impossible to assess whether verified credits are within the ex-ante estimate
  • FPIC was not conducted, and the auditor issued a corrective-action recommendation on the grievance mechanism
