Steel remains incredibly relevant and deeply integrated into the modern world. Steel is used extensively in engineering, construction and other applications vital to modern life. The downside is that traditional methods of manufacturing, based upon fossil fuels such as coal, are damaging to the environment as they produce significant quantities of carbon dioxide (CO2). In fact, according to McKinsey & Company1, steel production accounts for about 8% of global emissions. In 2018, every ton of steel produced emitted an average of 1.85 tons of CO2.
