The iron and steel industry is still dependent on fossil coking coal. About 70% of the total steel production relies directly on fossil coal and coke inputs. Therefore, steel production contributes by ~7% of the global CO 2 emission. The reduction of CO 2 emission has been given highest priority by the iron- and steel-making sector due to the commitment of governments to mitigate CO 2 emission
