“Steel parts account for approximately 60% of vehicle weight. Therefore, use of low-CO2-emission steel significantly contributes to reduced CO2 emissions throughout the entire vehicle’s life cycle. A significant portion of CO2 emissions originates from reducing iron ore in blast furnaces. With green steel, the aim is to reduce CO2 emissions by using raw materials from iron ore to low-carbon-reduced iron, or by switching from blast furnace to electric arc furnace,” Nissan said.
