CO₂ emissions and the steelindustry’s available responsesto the greenhouse effect

The Steel Industry has decreased its emissions of greenhouse gases by a factor of 3 in the last 30 years. However, the prospect of Global Warming, even if it is still a matter of controversy, makes it necessary to explore the issue further. Increasing steel recycling, i.e. the use of scrap, would be the most realistic nearterm answer of the Steel Industry to a further decrease in CO2 emissions. In the long term, some interesting R&D paths are left open.
