There have occurred a world-wide anxiety about global warming due to the increasing concentration of CO_2 in atmosphere. Among various countermeasures argued is the fixation of CO_2 in deep sea. This measure seems to be promising from the viewpoint of the huge amount of CO_2 to be treated, provided that the influence on the deep-sea environment be acceptable and that the cost and/or energy consumption would not make an impact on the economic situation. In this paper, CO_2 transportation system is studied at first, which consists of CO_2 loading on board at port, transport to planned sea area and sending CO_2 into deep sea. Three types of system are planned conceptually, each of which corresponds i) solid, ii) liquid and iii) hydrate for the CO_2 State of cargo, respectively. As a result, the fatal technical difficulties are not found so far as the transportation system. Furthermore, considering the merits and demerits of the three types comparatively, the one for liquid CO_2 is estimated main to be carried on to the next phase of study for the present. Secondly, the experimental investigation is performed. A pressure vessel filled with highly pressed artificial sea water is situated in the room of steady temperature. And liquid CO_2 is slowly injected. Consequently, it is experimentally confirmed that liquid CO_2 become heavier than sea water under condition of the waterdepth of more than 3000 meters. This is an evidence of the self-sinking of liquid CO_2 in deep sea more than 3000 meters.
