The production of high-carbon steel significantly contributes to environmental issues, primarily due to its high carbon emissions. Steel manufacturing is one of the most carbon-intensive industrial processes, responsible for 7% to 11% of global CO2 emissions. On average, producing one ton of steel results in 1.85 tons of CO2 emissions, highlighting the need for more sustainable practices in the industry.
High-carbon steel, particularly in the form of Advanced High-Strength Steels (AHSS), offers notable environmental benefits. AHSS can reduce a vehicle’s weight by up to 25%, which can lead to a 15% decrease in CO2 emissions over the vehicle’s lifetime. This weight reduction improves fuel efficiency, thereby lowering emissions during the vehicle’s operational life.
In the automotive sector, nearly 100% of steel is recycled each year, significantly reducing the need for new steel production. This high recyclability plays a crucial role in minimizing the environmental impact of steel. For every ton of recycled steel, approximately 1.787 tons of CO2 are saved. Life Cycle Assessment (LCA) studies further highlight that vehicles made with high-carbon steel often have a lower overall environmental impact. This is due to lower energy and emissions during manufacturing, significant mass reduction during use, and full recyclability at the end of the vehicle’s life.
Incorporating high-strength steels into vehicles enhances energy and resource efficiency. By reducing vehicle weight, high-strength steels improve fuel efficiency. This is especially important for trucks and cars with specialized drivetrains, leading to lower energy consumption and CO2 emissions. Additionally, using high-strength steel instead of conventional steel reduces the demand for natural resources, further decreasing emissions associated with material production. This approach aligns with global efforts to reduce the automotive industry’s environmental footprint.
