Environment & Ecology · Industrial Emissions & Climate Change
Consider the following statements regarding the emissions profile of the iron and steel sector: Assertion (A): Primary steel production through the conventional integrated route is among the more carbon-intensive industrial activities. Reason-I (R-1): In blast furnace-based production, carbon-bearing materials are used not merely as fuel, but also as reducing agents for iron oxides, generating carbon dioxide in the process. Reason-II (R-2): Several upstream and downstream stages of steelmaking, such as coking, sintering and heat-intensive processing, commonly involve fossil energy inputs that add to total emissions. Which of the following is correct?
