Total steelmaking capacity (thousand tonnes per annum)
Steel making capacity is generated from the Global Steel Plant Tracker (GSPT). The GSPT provides information on global crude steel production plants, and includes information on every plant currently operating at a capacity of one million tonnes per year (mtpa) or more of crude steel. The GSPT is currently being expanded to include all plants meeting the one mtpa threshold that have been proposed since 2017 or retired or mothballed since 2020. Steel plants consist of multiple units, depending on the iron and steel production method used. Crude steel is typically produced through coal-based methods (blast furnace and basic oxygen furnace or open hearth furnace) or electricity-based production (electric arc furnace charged with scrap metal, pig iron, direct reduced iron, or a combination). The GSPT map and underlying data are updated annually in January. Each plant included in the tracker is linked to a wiki page on GEM.wiki, which provides additional details. GSPT was accessed in July 2021 to generate this data.
