The world has recognized the shortage of energy resources. New and renewable energy development is the focus of much research and investment, and the world is trying to reduce carbon emissions. In November 2009, the Korean government announce a greenhouse gas emission reduction target of 30% by 2020. In this study, an underground heat exchanger was installed on the underside of the smart deep tunnel. The heat energy was calculated using the TOE conversion table from the Korea energy management corporation. Moreover, It is proposed to install heat exchanger in smart deep tunnel through reduction of carbon dioxide emissions and analyzing economic effects of carbon dioxide emissions reductions.
