New insights into the nation's carbon storage potential

Carbon sequestration is a method of securing carbon dioxide (CO₂) to prevent its release into the atmosphere, where it contributes to global warming as a greenhouse gas. Geologic storage of CO₂ in porous and permeable rocks involves injecting high-pressure CO₂ into a subsurface rock unit that has available pore space. Biologic carbon sequestration refers to both natural and anthropogenic processes by which CO₂ is removed from the atmosphere and stored as carbon in vegetation, soils, and sediments.
