Audit Analysis

The Loblolly Project is a subsurface biomass carbon removal and storage project under the Isometric standard with a 1,000-year permanence claim, yet the verification report requires longer polymer durability testing beyond the current 6-month assay and no buffer pool is documented. A significant discrepancy in the verified ERR figure (3,921.79 in an earlier verification report versus 1,454.13 in the later one) raises material over-crediting concerns, and eight material findings—including electricity consumption mismatches and misaligned carbon-content testing dates—indicate data-quality issues that were only partially resolved through corrective actions.

Red Flags

  • Verified ERR dropped from 3,921.79 (Feb 2026 verification report) to 1,454.13 (Mar 2026 verification report), a 63% reduction that signals a material correction or over-claiming in the earlier figure
  • 1,000-year permanence claim is supported by only 6-month polymer durability testing; the VVB explicitly requires longer assays as a corrective action
  • No buffer pool percentage is stated in any available document despite the 1,000-year permanence claim and a medium (7%) reversal risk score
  • Eight material findings in the verification report, including electricity consumption discrepancies of up to ~500 kWh and removal dates that do not align with carbon-content testing records
  • Methodology is at V1.0 (first version), meaning the approach has not yet been stress-tested through multiple verification cycles
