What Assheton brings to a board

Boards in critical minerals, natural resources, and sustainability face a distinctive set of pressures: tightening ESG regulation, supply chain due diligence obligations, investor scrutiny on responsible sourcing, and the strategic complexity of the clean energy transition. Assheton Stewart Carter has spent three decades working at the intersection of all of these - as a capital markets practitioner, impact investor, standards-setter, and operational leader in some of the world's most demanding mining jurisdictions.

That breadth translates directly into board value. He has chaired AccountAbility, directed The Copper Mark, co-founded the Fair Cobalt Alliance, and served on the standards committees of the Responsible Jewellery Council and Equitable Origin - giving him a rare command of both the governance frameworks boards must navigate and the commercial realities they operate within. His current roles at The Impact Facility, TDi Digital, and the Paris Peace Forum Transition Minerals Council reflect continued active engagement at the frontier of responsible investment and mineral traceability.

For companies seeking a non-executive director who can challenge management constructively on ESG risk, responsible sourcing strategy, and stakeholder engagement - while bringing credible international networks across business, government, and development finance - Assheton offers a combination that is genuinely difficult to replicate.
