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.
