The steel industry is a significant contributor to global carbon emissions, accounting for around 7% of all emissions. As such, decarbonising steel production is crucial for achieving global climate goals and reducing the impact of human activity on the environment. There are several ways to decarbonise the steel industry, including the use of alternative raw materials, such as recycled steel and iron ore, as well as the adoption of new technologies and processes that reduce carbon emissions during the steel-making process. In this article, we explore some of the challenges, benefits and processes of decarbonising steel production.
