Carbon sequestration is the process of capturing and storing carbon dioxide to prevent it from entering or remaining in the atmosphere. Natural sequestration occurs through forests, soils, and oceans absorbing carbon. Technological sequestration involves capturing CO2 from industrial sources or directly from the air and storing it underground or in products. Carbon capture and storage (CCS) technology at industrial facilities captures emissions before release. Enhanced natural sequestration includes protecting and expanding forests, improving soil carbon storage through agricultural practices, and restoring wetlands. Sequestration is increasingly discussed as part of climate strategies, though debate exists about its feasibility, cost, and whether it distracts from emission reduction.
