Abstract: The goal of this paper is to quantify baseline emissions and to analyse CO₂ global emission reduction potentials in the iron and steel life cycle. First the paper discusses current CO₂ emissions in the global iron and steel industry. Next, the global emission reduction potentials are analysed. According to this study, global CO₂ emissions in the life cycle of iron and steel amounted to 2100-2450 Mt CO₂ in 1999. This represents 9-10% of the global total CO₂ emissions from fossil fuel use and industrial processes. Two thirds of this emission is accounted for by coal use. Upstream emissions in electricity production and in transportation are also important. During the next two decades, emissions can be reduced by more than 1000 Mt. This emission reduction can be achieved at cost levels below 2,000 ¥/t CO₂ (125 ¥ = 1 US$). This cost level is low, compared to other industrial emission sources.

Keywords: iron and steel; CO₂ emission reduction; emission mitigation technology; energy efficiency; fuel substitution; CO₂ removal; recycling.
