Overview

• Mati Carbon secured the $50 million grand prize in the XPRIZE Carbon Removal competition for its basalt-based enhanced rock weathering approach.
• The technology sequesters CO₂ for millennia by spreading crushed basalt on farmlands, which also improves soil fertility and water retention.
• Mati expects to deliver 5,000–6,000 metric tons of carbon removal credits in 2025, funded through grants and carbon credit sales.
• The company plans to expand operations to three additional Global South countries this year, targeting smallholder farmers for co-benefits.
• Runner-up NetZero received $15 million for its biochar technology, which turns crop residues into carbon-storing particles that enhance soil health.
