Carbon Sequestration Basics

Concerns over climate change are promoting the development of carbon management strategies, including carbon sequestration. Carbon sequestration options include geologic, terrestrial and ocean sequestration. Geologic sequestration options include direct injection into geological formations, including coal seams that cannot be mined, saline aquifers and depleted oil and gas reservoirs. Terrestrial sequestration is aimed at enhancing the uptake of carbon dioxide from domestic terrestrial ecosystems. Ocean sequestration includes both injection into deep areas of the ocean and increased stimulation of ocean surface waters to grow phytoplankton and take up carbon dioxide.
