MATI Enhanced Rock Weathering Credits

Mati Carbon PBC is a public benefit company with a Houston, Texas address in its privacy policy. It works in seven countries across Asia and Africa and aims to benefit more than 100 million farmers by mid-century through durable carbon removal.

MATI spreads natural rock dust on smallholder farms through enhanced rock weathering, which raises yields, corrects soil acidity and removes CO2. Carbon removal is measured after it occurs rather than sold in advance. The company reports 36,000+ farmers engaged and 300,000+ tons of rock dust spread, with credits issued on the Puro.earth and Isometric registries.

• Rock dust deployment: natural rock dust spread on smallholder farmland in Asia and Africa.
• Measured removal: carbon removal verified after it occurs, not pre-sold.
• Dual registry issuance: credits issued on Puro.earth and Isometric.
• Transparency hub: public publications and a MATI Sandbox tool for scientific data.
• Science partnerships: IIT Kanpur, Yale University and University of Sheffield.

Vietnamese corporates with net-zero commitments can add MATI credits to a durable removal portfolio. Agricultural research institutes in Vietnam could partner on rock-dust field trials on acidic soils. Fertilizer and agri-input distributors could study the smallholder delivery model.

Buyers receive verified removal credits issued on both Puro.earth and Isometric, with a BeZero AA pre-rating. Payment follows measured removal rather than promises. Farmers see more than 30% higher household income according to the site. Early buyers include Stripe, Shopify, Frontier, Siemens and H&M.

Buyers of high-integrity carbon removal increasingly ask for measured, registry-verified tonnes, and enhanced rock weathering is moving from pilots to certified issuance. Tropical smallholder farmland in Asia is a growth area, which is relevant to Vietnam's large rice and crop-growing regions.
