Transforming Mine Waste into a Net Zero, Multibillion-Dollar Opportunity

Authored by Arca, The Climate Agency, a nonprofit consultancy, and Will MacNamara, former Financial Times natural resources correspondent, the paper outlines how mine waste consisting of mafic and ultramafic rock can remove carbon dioxide from the atmosphere at scale—representing one of the great untapped resources for a low-carbon economy.
A US$100 billion annual revenue stream for mining
The white paper examines the geological potential, technical innovations, commercial pathways, public incentives, and sustainability benefits of the opportunity.
Key highlights:
- Annual revenue potential of US$100 billion, based on the long-term carbon credit price forecast
- US$870 billion one-off revenue opportunity from inactive mines
- A practical roadmap for mining companies to realize the carbon mineralization opportunity
