stituents from the coke and iron ore. Although some carbon is retained in the iron (typically 4 percent carbon by weight), most of the carbon is emitted as CO 2. Emissions also occur, although to a much lesser extent, during the production of steel. CO 2 emis sions occur as carbon present in the iron is oxi dized to CO 2 or CO. The produced ...
