| Summary: | Global CO<sub>2</sub> emissions caused by the burning of fossil fuels over the past century are presented. Taking into consideration the total world production of more than 1,3 billion tons of steel, the steel industry produces over two billion tons of CO<sub>2</sub>. Reductions in CO<sub>2</sub> emissions as a result of technological improvements and structural changes in steel production in industrialized countries during the past 40 years are described. Substantial further reductions in those emissions will not be possible using conventional technologies. Instead, a radical cutback may be achieved if, instead of carbon, hydrogen is used for direct iron ore reduction. The cost and the ensuing CO<sub>2</sub> generation in the production of hydrogen as a reducing agent from various sources are analysed. |
