What Is CO2 Sequestration?
CO2 sequestration means capturing CO2 and putting it into environmentally sound long-term storage. There are two types of sequestration: direct and indirect. Direct sequestration involves capturing anthropogenic CO2 at a source before it can be emitted to the atmosphere. The most efficient concept would use specialized equipment to capture anthropogenic CO2 at large stationary sources like factories or power plants and then inject the CO2 into secure storage zones deep underground (geologic sequestration) or into the deep ocean. Terrestrial sequestration involves removing CO2 from the atmosphere. Terrestrial sequestration uses land management practices that boost the ability of plants to capture CO2 from the atmosphere, regardless of its source, and then store it in plant material or soil for a long period of time. Opportunities for terrestrial sequestration can be found in forests, grasslands, wetlands, and croplands.
