A Billion-Tonne Vision: The Company Using Rocks to Remove Carbon and Boost African Agriculture with Sam Davies

Episode 182 with Sam Davies, CEO and Co-Founder of Flux, a pioneering climate-tech company based in Nairobi that’s scaling Enhanced Rock Weathering (ERW) to remove carbon from the atmosphere and restore Africa’s soils. A former British Army reconnaissance officer, Sam transitioned from military leadership to climate entrepreneurship, driven by a personal vision to contribute meaningfully during the climate crisis.

After discovering carbon removal while producing the documentary Legion 44 in Kenya, Sam founded Flux to unlock Africa’s immense potential for ERW, a natural process that sequesters CO₂ while improving crop yields and regenerating farmland. Under his leadership, Flux has formed key partnerships with governments like Nigeria’s, launched pilot projects across multiple countries, and committed to removing one billion tonnes of CO₂ from the atmosphere.

In this episode, Sam explores the science behind ERW, the social impact of regenerative agriculture on smallholder farmers, and how Flux is building one of the most promising carbon removal platforms on the continent. He also unpacks the urgent need for credible carbon credits and policy innovation and why Africa is the next frontier for scalable climate solutions.

What We Discuss With Sam

• Why Enhanced Rock Weathering (ERW) is one of the most promising, and underutilised pathways for permanent CO₂ removal at scale.
• How Flux’s ERW model not only captures carbon but also regenerates depleted soils, improves crop yields, and enhances farmer livelihoods across Africa
• Flux’s strategic partnerships with governments, including Nigeria’s, and the role of policy and public-sector collaboration in unlocking climate solutions.
• The structure behind Flux’s carbon credits, including measurement protocols and global certification standards for permanence and integrity.
• The long-term vision to capture one billion tonnes of CO₂
