China is the largest and most carbon-intensive steel producer, significantly contributing to global greenhouse gas emissions. Steelmaking accounts for 7-8% of these emissions, making decarbonization challenging.

In the US, Nucor (NUE) and Steel Dynamics (STLD) are leading in green steel production, utilizing electric arc furnaces and high scrap inputs. NUE aims for net-zero steel at scale, while STLD reports 82% recycled or internally produced inputs. However, high production costs and limited access to green hydrogen and renewable resources hinder the scalability of green steel projects.
