Since the amount of CO 2 emissions from the steel sector in 2013 was 200 million
tons per year, the amount of emissions will be 40 million tons for the same level of
production if we achieve an 80% reduction in 2050. Among the current CO 2 emissions, the amount of emissions attributed to power generation is 51 million tons,
which can be reduced by 80% if we use future low carbon power supplies. The issue
is how to reduce other emissions from within the steel production process.
Table 5.4 is an illustration of the steel production in 2050 when such a significant
reduction is achieved. There are two major methods of steel production: the Blast
Furnace Method using iron ore as a raw material and the Electric Furnace Method
using iron scrap as a raw material. Table 5.4 displays simulated images of the steel
industry in 2013 and 2050. The supply and demand of steel by each manufacturing
method, and the amount of CO 2 emitted in correlation with steel supply are presented in the figure. The situation in 2050 is based on the following five
assumptions.
