United States Steel Corp. plans to reduce greenhouse-gas-emissions intensity across its global footprint by 20%, as measured by the rate of carbon dioxide (CO2) equivalents emitted per ton of finished steel shipped, by 2030 based on 2018 baseline levels. This target will apply to U.S. Steel’s global operations. The company plans to achieve this goal through multiple initiatives, including the development of electric-arc furnace (EAF) steelmaking at its Fairfield Works and at Big River Steel, in which U.S. Steel recently acquired a minority interest with an option to acquire the remainder over the next four years.
Further carbon-intensity reductions are expected to come from the company’s introduction of endless rolling and casting technology and construction of a cogeneration facility at its Mon Valley Works, which was announced in May, as well as implementation of ongoing energy-efficiency measures and continued use of renewable energy sources.
According to U.S. Steel, the carbon-intensity reduction target reflects its commitment to continuous improvement in production efficiency and builds on its XG3™ advanced high-strength steel, which enables automakers to manufacture lighter-weight vehicles that meet federal corporate average fuel economy (CAFE) standards with reduced carbon emissions.
