Stack Carbon delivers verifiable, permanent carbon removal solutions through Enhanced Rock Weathering (ERW) and Biochar projects in Africa. ERW accelerates CO2 mineralization by applying crushed basalt rock to farmland, while Biochar sequesters carbon by converting agricultural waste into soil amendments. These durable solutions help organizations meet sustainability targets while regenerating land and providing co-benefits to smallholder farmers.

Problem
Smallholder farmers in Africa often face challenges related to degraded croplands, low crop yields, and limited economic opportunities, contributing to food insecurity and hindering sustainable development. Current carbon removal projects may not always prioritize the needs and direct involvement of these communities.
Solution
Stack Carbon partners with smallholder farmers in Africa to implement community-led carbon removal projects, focusing on enhanced rock weathering and biochar application. This approach aims to regenerate degraded soils, improve water retention, and increase nutrient availability, leading to enhanced crop yields and greater climate resilience. By directly involving local communities in the development and management of these projects, Stack Carbon ensures that solutions are tailored to local needs and provide direct economic opportunities, fostering sustainable rural development alongside carbon sequestration. The company's model delivers measurable impact across soil health, food security, and community empowerment.
