Metamorphosis or Steel is always Sustainable in Climate Change

Abstract:
Steel is an important material for the industrialization of the world. The problem of climate change eases politicians to reduce CO2 emissions. Steel produces around 4 % of the worldwide CO2 emissions and is under pressure from emission trading. But if climate change increases further, caused by humans or not, steel becomes an indispensable material for the world society.
Steel was and still is a sustainable material. Hundreds of years ago there was an evolution from weapons to ploughshares. In the last decades, its features have extremely increased. And steel has a very high recycling rate.
A lot of investigation (ULCOS) in the last ten years show ways of steelmaking in the future, but a real breakthrough was not found yet. The dilemma of steel as a sustainable and needed material and a certain amount of CO2 emissions with its production still exist.
Political measures to reduce CO2 emissions from steelmaking by increasing costs will not help society on the long run.
Conclusion: Special material needs a special solution in political decisions. The European way of emission trading will not help on the long run to keep the steel production in Europe. And if the CO2 reductions of the world society will not stop climate change, steel is needed more than ever and even in Europe!
