In 2025, Steel Dynamics completed a corporate carbon footprint assessment and publicly disclosed its greenhouse gas (GHG) emissions according to the GHG Protocol, covering Scope 1 (direct emissions from owned or controlled sources), Scope 2 (indirect emissions from purchased energy) and Scope 3 (indirect emissions across the value chain).
However, Steel Dynamics has not published a category-level breakdown of its Scope 3 emissions, limiting visibility into specific value chain sources.
