Map of global iron and steel infrastructure in 2019

The GID-Iron and Steel Emission Database (GISD) provides CO2 and air pollutant emissions as well as underlying information of global multi-process iron and steel plants. GISD is based on the integration of global and regional iron and steel plant database such as the Metal Consulting International Limited (MCI) database created by James King (King, 2019). We compiled, combined, and harmonized the available data related to iron and steel production facilities including production of coke, sinter, pellet, iron (blast furnace, direct reduction and electric furnace), and crude steel (electric arc furnace, basic oxygen furnace, and open hearth furnace) from database described above, and filled data gaps with modelled emissions.

The GISD provides up-to-date elementary information and high-resolution emissions from global iron and steel plants, which includes plant-level, national, and regional capacity and age information, as well as anthropogenic emissions of CO2 and various air pollutants (SO2, NOx, primary PM, VOCs, CO, black carbon, and organic carbon). For elementary information which is obtained from collaborators’ database and restricted by user’s license (e.g., MCI), we provide cross-links to the original database. Users can purchase the relevant database and merge with GISD to get complete information at plant level.

The GISD v1.0 includes a consistent time series of emissions and underlying information for global iron and steel plants by integrating several global and regional databases. The GISD v1.0 is based on the MCI database (King, 2019) to compile the basic operational information of iron and steel facilities, and calibrated by local database in China (Wang et al., 2019). The current GISD v1.0 dataset provides company ownership, plant name, plant location, crude steel capacity, and CO2 emissions in 2019 for each iron and steel plant, where the underlying information at plant level were obtained from MCI. GISD v1.0 dataset also provides summary of capacity, and age distribution by country and by region, in which China’s data were calibrated by the local database developed by Wang et al. (2019). Emissions of air pollutants and emissions for other years will be available once they are finished.

The GID team will timely update air pollutants and carbon dioxide emission inventory and continuously provide high-quality data products by integrating more high-resolution local datasets. If you are looking for more detailed emissions and potential collaboration, please contact us.

Development History >

The development of GID-Iron and Steel Emission Database started in 2020 and we will keep tracking and updating infrastructure changes and related emissions periodically.

  • In February 2021, GISD v1.0 product is released. This online dataset provides basic information of global iron and steel infrastructure and related CO2 emissions in 2019 with different aggregated levels (global summary data for number of plants, total capacity and CO2 emissions, region-level and country-level data for capacity, age and CO2 emissions, and plant-level data). Emissions of air pollutants and emissions for other years will be available once they are finished.
