Audit Analysis

ReGenerate Livermore Falls is a biochar carbon-removal project verified by 350Solutions under the Puro standard. Additionality is confirmed via an investment test and permanence is supported by landfill sequestration, but the project-specific baseline, absence of a documented buffer pool, and lack of any leakage treatment leave meaningful gaps in the integrity case. Documentation is recent and of high extraction confidence, though several key parameters (FNRB, usage rate, crediting period, CORSIA status) are not stated in the available record.

Red Flags

  • No buffer pool percentage is stated in any available document, leaving permanence risk for this removal credit unquantified
  • Leakage deduction and justification are entirely absent from the extracted record despite the project type
  • Project-specific baseline method used rather than a jurisdictional or standardised approach, increasing over-crediting risk
  • Material finding: end-user declaration of no carbon-removal claims was initially missing (subsequently provided), raising a transient double-claim risk
