The gases that cause the greenhouse effect such as unusual atmospheric phenomena or average temperature rise are carbon dioxide, methane, oxidized nitrogen, carbon chlorides, ozone or water vapor, among which carbon dioxide occupies more than 80% of all the discharged gases. All over the world, there is a growing tendency to exploit various substitute or clean energy sources as well as to control fossil fuels for the sake of diminishing the gases that cause the greenhouse effect. But, to satisfy the regulations that have become strengthened for the reduction of the gas, it is necessary to sequestrate as well as to dispose or collect the carbon dioxide, which is produced 7 billion tons a year. The paper will be focused on the necessity of the carbon dioxide sequestration, and the disposal methods in the geologic strata or in the ocean that have been discussed and experimented up to now.
