Carbon sequestration is the long-term removal, capture, or sequestration of carbon dioxide from the atmosphere to slow or reverse atmospheric CO 2 pollution and to mitigate or reverse climate change. Carbon dioxide is naturally captured from the atmosphere through biological, chemical, and physical processes.

What things sequester carbon?

using subsurface saline aquifers, reservoirs, ocean water, aging oil fields, or other carbon sinks, bio-energy with carbon capture and storage, biochar, ocean fertilization, enhanced weathering, and direct air capture when combined with storage.

Why is sequestered carbon important?

Carbon sequestration is simply the intake and storage of the element carbon. ... Because they soak up the carbon that would otherwise rise up and trap heat in the atmosphere, trees and plants are important players in efforts to stave off global warming in a process called climate change mitigation.
