Carbon sequestration describes the process of removing carbon dioxide from the atmosphere. Carbon sequestration usually occurs naturally through absorption of carbon dioxide by trees and the oceans. However, today there are a variety of technologies being researched to try to artificially capture and storing carbon. There are two ways of carbon sequestration being explored. One way is to enhance the existing natural carbon sequestration process and another way is to capture and store carbon artificially.

Most methods of enhancing natural carbon sequestration are already being implemented. One way that is widely implemented is the planting of trees and forests. However, the rate at which forests can absorb carbon, given the available land, is far exceeded by the rate at which it is released by the burning of fossil fuels. To reduce U.S. carbon emissions by 7%, as set by the Kyoto Protocol, would require the planting of a...
