“…Zhang et al [10] used the WIOD (2013) to study of the global impact of the construction sector by means of a hypothetical extraction method (HEM), and they evaluated the impact of backward and forward CO 2 emission linkages in the construction sector. On the other hand, Yokoyama [4] used the WIOD (2013) to analyze the construction EGs of each country. In this study, CO 2 emission intensity was calculated for 35 sectors in 40 countries, and the construction EGs of each country and the composition of each sector's input to construction were analyzed.…”

“…Since this analysis targeted domestic CO 2 emissions in each country and did not consider overseas spillover effects, the IO tables of domestic goods were used for this analysis. The calculation procedure according to Yokoyama [4] is described below.…”

“…WIOD (2013) provides IO tables for 40 countries in 35 sectors. An analysis using the WIOD (2013) was conducted by Yokoyama [4] in Japanese. However, an analysis using the WIOD (2016), which includes increased number of sectors, as well as target countries, allows for a more precise analysis.…”

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

El funcionamiento de los cementos activados alcalinamente consiste, en términos generales, en una reacción de un material base o precursor compuesto por aluminosilicatos y un material activador con altas concentraciones alcalinas. La naturaleza de estos materiales se explica en el sistema de fases ternarios (Silicio-Calcio-Aluminio) que forman la base de un cemento alcalino.Los materiales más habituales utilizados para la formación de cementos activados alcalinamente se muestran en este diagrama de la Imagen 10.
