BHP submitted an Expression of Interest to the Australian Carbon Credit Unit (ACCU) Scheme in July 2024 for a carbon mineralisation methodology using enhanced air capture with alkaline waste materials. The submission was assessed by the Emissions Reduction Assurance Committee (ERAC), an independent statutory body evaluating compliance with the Offsets Integrity Standards. The EOI included a project plan detailing the permanent CO2 removal methodology via enhanced air capture and ex situ mineralization with ultramafic materials, along with supporting documentation including a cover letter and CV. Personal details of the BHP contact were redacted under privacy provisions. The disclosure does not reveal ERAC's assessment outcome, specific environmental impacts, or quantified carbon credit projections for this methodology.
