Scaling Impact-Driven Climate Action in Africa
With Co-Benefits to Smallholder Farmers
Who We Are
Stack Carbon is a pioneering climate tech innovator committed to a new model of climate action. We confront the dual challenges of climate change and agricultural degradation head-on, leveraging Africa’s unique potential to deliver verifiable, scalable, and equitable climate solutions. Our work is rooted in two core solutions: Enhanced Rock Weathering (ERW), which applies finely crushed basalt rock to farmlands to permanently capture atmospheric CO2, and Biochar, which pioneers a circular economy by converting biomass waste into valuable resources.
The African Opportunity
Africa stands as a vital frontier in climate action, offering immense opportunities for impactful and scalable solutions. Our projects are strategically located to maximise both climate impact and community empowerment.
Through this targeted approach, we are demonstrating how localised projects can deliver global climate benefits while directly improving livelihoods in the communities we serve.
Envisioned Impact by 2050
Our vision is to achieve a monumental scale by 2050, delivering a profound and lasting impact on both the planet and its people. This is a dynamic, data-driven look at the future we are building:
100M+ Tonnes of CO2 Targeted:
Our projects are designed to permanently remove tens of millions of tonnes of carbon from the atmosphere.
1M+ Hectares Regenerated:
Through our Enhanced Rock Weathering projects, we aim to regenerate over one million hectares of farmland.
Jobs & Farmers Engaged:
We will create sustainable employment opportunities and directly empower millions of farmers.
Our Solutions
Stack Carbon offers durable, science-backed carbon removal solutions that deliver measurable climate impact and meaningful community benefits. Through Enhanced Rock Weathering and Biochar, we help organizations meet sustainability goals while regenerating land and supporting African smallholder farmers.
Enhanced Rock Weathering:
Our ERW projects accelerate natural carbon mineralization by applying finely ground basalt rock to farmland. CO₂ reacts with the rock, forming stable compounds stored safely for centuries.
Co-benefits:
Boosts soil nutrients and crop yields
Increases water retention
Creates local jobs
Verified, permanent carbon removal
Biochar:
We transform agricultural residues into biochar, a carbon-rich soil amendment that sequesters carbon and enriches soils.
Impact:
Reduces methane from waste
Improves soil fertility
Enhances crop resilience
Long-term CO₂ storage
