The table of energy consumption and CO 2 emission intensities is calculated, which is based on 2005 I0 tables in Japan. In this table, intensities of energy consumption and CO 2 emission are shown as values of MJ and kg-CO 2million Yen, and each values are shown as based on producer's and purchaser's prices. It can be possible to calculate embodied energy and CO 2 emissions due to constructions of various buildings in Japan. Margins in intermediate sectors and purchaser's are calculated and compared between whole industries and building industry. Margin of purchaser's prices are shown in Japanese IO table, therefore CO 2 emissions due to transportation from the factories to building site can be also calculated. Building industry is adjudged to be large CO 2 emission industry concerning transportation compared with the value of production.
