Recently, Information Technology (IT) has spread quickly in Japan. In this study, we developed a model to estimate the influence of IT on industrial economy and to estimate the related environmental load. This model consists of two modules, input-output analysis module and energy conversion module. The former module estimates multiplied effects of adoption of IT on industry economy, and the latter module calculates CO2 emission by using the relationship between the emission and industrial production. An IT spreading scenario including evolution of broadband network, electronic commerce (BtoB and BtoC), and telework was considered. As a result of our estimation, demand for power sector increased, and CO2 emitted from oil products decreased due to reduction of transportation. Total CO2 emission increased because of large amounts of demands for the power sector.
