Spreading crushed rock over farmland can remove CO₂ from the atmosphere if we do it right
- Written by Paul Nelson, Associate Professor of Soil Science, James Cook University
Carbon dioxide (CO₂) is naturally removed from the air when it reacts with certain types of rock. We can accelerate this process by crushing suitable rocks and spreading them over agricultural fields. This simple method, known as “enhanced rock weathering”, could vastly increase the rate of CO₂ removal from the...
