Carbon sequestration refers to processes that store or “lock” carbon from the Earth’s atmosphere into plants, soils, rocks, oceans and the build environment.
Carbon sequestration happens all the time. Plants draw carbon out of the atmosphere and use it to grow their leaves, branches, trunks and roots. When the plants die – or are eaten and excreted by animals – some of that carbon can end up deep in the soil for a very long time.
Sequestration can be encouraged. Planting more trees or expanding areas of forests, grasslands or wildlands would allow more plants to draw down greater amounts of carbon dioxide and transfer some of that carbon into the ground.
Carbon from the atmosphere can be captured – from waste, emissions are directly from the atmosphere – and integrated into infrastructure, such as concrete, asphalt, building materials or green infrastructure projects.
