Q: What is terrestrial sequestration?

A: Terrestrial sequestration is a process that captures and stores carbon dioxide (CO2) in vegetation and soil within a few feet of the Earth’s surface, providing them with the components they need to live and grow and reducing CO2 in the atmosphere. During photosynthesis, carbon from atmospheric carbon dioxide is transformed into components necessary for plants to live and grow. As part of this process, the carbon present in the atmosphere as carbon dioxide becomes part of the plant in a leaf, stem, or roots, and the carbon is sequestered for a long period of time. Once the tree dies, or as limbs, leaves, seeds, or blossoms drop from the tree, the plant material decomposes and the carbon is released.
