Outline of Final Research Achievements

To realize low carbon societies, it is essential to reduce CO2 emission from energy-intensive sector, such as a steel. This research develops a material stock and flow model and analyzes reduction potentials of steel demand and CO2 emission. Target region is a world which is divided into 35 regions and an estimation period is from 2005 to 2050.
By introduction of countermeasures (control of service demand, efficiency improvement of goods stock, technology progress), steel demand in 2050 is reduced 33 % compared with that in a no-countermeasure case. When promoting production process shift to an electric arc furnace with considering constraints of the both supply side of iron scrap and demand side of goods-wise crude steel production, the CO2 emission reduction potential from 2005 is 6%.
