8 kwi 2022 · Every tonne of scrap recycled avoids about 1.5 tonnes of CO2 emissions, as well as reduces the need for iron ore, coal, and limestone.1 U. S. Steel has been recycling steel and other byproducts for as long as we have been manufacturing steel. Today, we recycle approximately 3 million tons per year.
Although producing steel is carbon-intensive, we have a roadmap to get to net-zero Scope 1 and Scope 2 emissions by 2050. Approximately 70% to 80% of the greenhouse gas (GHG) emissions from integrated steelmaking are associated with the use of coke and coal to melt iron in blast furnaces.
U. S. Steel uses two primary production processes to make steel: the integrated route relies on blast furnaces (BF) and basic oxygen furnaces (BOF), while the mini mill route uses electric arc furnaces (EAFs). Each route uses different raw materials and energy sources, leading to different levels of greenhouse gas (GHG) emissions.
U.S. Steel strives to minimize our environmental footprint by implementing greenhouse gas (GHG) reduction and air-quality goals while meeting other environmental standards. We engage with our stakeholders throughout the year and report on our performance to relevant groups across our organization.
The U.S. steel industry’s final energy and CO2 emissions intensities rank 4th lowest among the countries studied. Figures ES1 and ES2 show the CO2 emissions intensities for the BF-BOF and EAF steel production routes for the fifteen countries studied.
3 kwi 2024 · CarbonFree’s SkyCycle™ technology will capture and mineralize up to 50,000 metric tons of carbon dioxide annually at U. S. Steel’s facility in Gary, Indiana, to convert emissions into specialty-grade, carbon-neutral calcium carbonate.
The steel industry is a major contributor to global carbon pollution, accounting for 7 percent of all greenhouse gas emissions. If current trends continue, the steel industry is projected to consume up to 25 percent of the remaining 1.5°C carbon budget by 2050.
