The energy consumption and CO2 emission of Swedish production of flat and l
ong products of structural steel have been assessed by means of LCl data fr
om the IISI study. Two general factors reduce the expenditure of energy and
CO2 emission in Swedish production of both flat and long products: energy
efficient steel processes; and extremely low CO2 emissions for generation o
f electricity. For flat steel products two specific features also contribut
e to their low energy consumption and CO2 emission: the use of magnetite ir
on ore instead of hematite; and a product programme with a uniquely large s
hare of high strength steels. The latter allows significant weight savings
in end products, thus resulting in global net reductions of energy consumpt
ion and CO2 emission. Even when transport of Swedish products to export mar
kets are included, the Swedish figures are more favourable than those of st
eels manufactured domestically in their respective markets.
