Reduction of CO_2 emission into the atmosphere has been one of the important concerns in the various fields of human activities for prevention of the climate change in global size. CO_2 contained in the exhaust gas from ships is also considered to be the reduced one , for which improvement of ship's propulsive performance and fuel oil consumption reduction etc. has been earnestly investigated. In this paper dissolution of CO_2 in the exhaust gas bubbles injected into the flow around ship hull is proposed to be one of the powerful candidate for resolution, taking into account the hydrodynamic characteristics of flow around ship hull and chemical property of CO_2 in the large amount of salt water around ships. The system outlined is composed of exhaust gas bubbles injection system, including power needed for injection, hydrodynamics of micro gas bubbles flowing along the ship hull of full scale accompanied with chemical process of CO_2 dissolution, reduction of ship's frictional resistance.
