US Southeast Enhanced Weathering Project

Audit Analysis

The Lithos Enhanced Rock Weathering project presents a scientifically credible permanence case (ocean storage exceeding 10,000 years) but is in a very early documentation stage with only a PDD and stakeholder consultation on file. The absence of an independent verification body, a quantified leakage assessment, and the presence of material findings—including concerns about extensive redactions limiting public evaluation—significantly constrain confidence in the project's integrity and transparency.

Project Description

Red Flags

• ⚠Material finding flags 'extensive redactions limiting public evaluation' of the PDD, undermining independent scrutiny of the methodology
• ⚠No verification body (VVB) is identified in any available document, leaving additionality verification unconfirmed
• ⚠Corrective actions are still outstanding (equation error in section C.3, missing subsampling strategy details in public PDD)
• ⚠Leakage is deemed negligible without any quantified deduction or detailed justification in the extracted record
• ⚠Storage permanence independent verification not found in available documents
