The iron and steel sector contributes nearly 7% of global anthropogenic GHG emissions. As global climate commitments tighten and industrial decarbonization becomes urgent, green steel, produced using low-carbon alternatives such as green hydrogen and renewable electricity, has emerged as a potential solution.
