Abstract

Energy consumption and CO2 emissions are collectively known as the embodied impact. The current study calculated energy intensity and CO2 emission intensity based on the 2011 Input-Output (I-O) Tables for Japan, and it compiled those values into an intensity database. This study analyzed the EG of the Japanese building and construction sectors, and the following findings were obtained: 1) Research on EE and EG (EEG) has been conducted by the IEA EBC Annex 57 project. 2) EG by the construction sector accounted for 14.2% of total CO2 emissions in Japan. EG decreased every year from 20.3% in 1995.
