Audit Analysis

The Brandon Production Facility is a carbonated building material project verified by 350Solutions under Puro.earth's 2022 methodology. Additionality is confirmed via an investment test, but the project lacks a stated buffer pool, leakage treatment, and any safeguards (no FPIC, no grievance mechanism). Two corrective actions were required, including a CORC calculation error and a marketing disclaimer, and the verified ERR was revised downward by roughly 28% between the August and December 2024 reports.

Red Flags

  • Verified ERR dropped from 20,831 (Aug 2024 report) to 14,873 (Dec 2024 report) after a CORC calculation correction was required, indicating the initial claim overstated removals by ~28%.
  • No leakage deduction or justification is stated in any available document for a project type where displaced material or supply-chain shifts could generate leakage.
  • No buffer pool percentage, reversal tracking, or permanence mechanism is documented, leaving the long-term integrity of the carbonated material's stored carbon unquantified.
  • No FPIC was conducted, no grievance mechanism exists, and benefit sharing is not described, indicating a gap in community and stakeholder safeguards.
