Key Phrase Activity Logo We have decided to actively work to achieve zero-carbon steel as a top priority management issue, and have established a new "Key Phrase" to summarize our environmental management and an "Activity Logo" to represent our activities as our "Environmental Brand Mark". We will make a concerted effort to tackle these extremely difficult issues. © 2021 NIPPON STEEL CORPORATION All Rights Reserved. 5 Zero-Carbon Steel: Our CO2 emissions reduction scenario 2030 Target Total CO 2 emissions (MT/Y) (Vs. 2013) 30% 30% or more reduction in total CO2 emissions vs. 2013 reduction [Means] • Actual implementation of the COURSE50 in the existing BF and BOF process • Reduction of CO2 emissions in existing processes 102 • Establishment of an efficient production framework.

Iron ore needs to be reduced 11 In nature, iron exists as oxides, iron ore. To produce steel products, oxygen must be removed (= reduced) from iron ore. The use of carbon (coal) is the best, stable, cost-effective method for reducing iron ore in large quantities. The reaction, however, emits CO2. Carbon (C) removes the From iron ore that oxygen (O) (reduction) in the exists as iron oxides iron ore as carbon is more Steel is (e.g., Fe2O3) in nature, reactive than iron (Fe). produced.
