Study on Worldwide Embodied Impacts of Construction: Analysis of WIOD Release 2016

Net-zero-energy buildings (ZEBs) that contribute to making annual energy consumption balances zero are effective measures for reducing greenhouse gas (GHG) emissions in the construction sector. As application of ZEBs progresses, GHG during and manufacturing materials products (called EG) account a relatively large proportion overall emissions. This study aimed clarify EG as means by which formulate policies reduction each country. The EGs 43 countries from 2011 were analyzed. 56-sector input/output table CO2 emission data 2016 World Input/Output Database, published EU, both used this analysis. It was found sector accounted highest total Moreover, fraction tended be higher developing such China India, while developed lower EG. Construction shown heavily influenced sectors manufacture “cement”, “steel bars steel frames”, “energy sources”. Thus, it is very important advance technological developments reduce within these sectors. variation 2000 2014 showed increasing, whereas have been decreasing slightly.
