Biochar is a kind of charcoal that removes CO2 from the atmosphere, helping yield healthy crops and even producing abundant renewable energy in the form of electricity as it's made. This exciting climate change fighter is ready for scaling now. Entrepreneur Axel Reinaud outlines three ways to make this material more accessible to farmers -- so that our food system, energy grid and the climate can all reap the benefits.

How biochar removes CO2 from the air -- and helps farmers thrive

Biochar, a stable form of carbon made from biomass, is transforming agriculture by improving soil and fighting climate change.

By turning agricultural residues into biochar, farmers like Mr. Ewané can enhance crop yields, reduce fertilizer use, and generate energy.

Embracing biochar could remove billions of tonnes of CO2 annually, offering a scalable solution to restore our climate balance.
