    Iron and Steel Analysis IEA

    Demand for steel which drives steel production is a key determinant of energy demand and steel subsector CO 2 emissions. Global crude steel production increased by 5 in 2018 to reach 1 817 Mt following 6 growth in 2017. Initial estimates suggest 3 growth in 2019. This follows a period of relatively flat demand from 2013-2016.
