Steel Dynamics

Steel Dynamics, a US-based company in the basic iron and steel industry, reported total emissions of approximately 8.55 billion kg CO2e in 2025. This includes about 1.95 billion kg CO2e from Scope 1 emissions and approximately 5.23 billion kg CO2e from Scope 3 emissions. No Scope 2 data was disclosed for 2025. In 2024, the company's total emissions were around 8.62 billion kg CO2e, comprising approximately 2.85 billion kg CO2e in Scope 1 emissions, 1.63 billion kg CO2e in Scope 2 emissions (market-based), and 5.52 billion kg CO2e in Scope 3 emissions. Key contributors to Scope 3 in 2024 included purchased goods and services (approximately 4.85 billion kg CO2e), fuel and energy-related activities (around 924.67 million kg CO2e), and upstream transportation and distribution (about 505.81 million kg CO2e).

Steel Dynamics has set ambitious climate commitments. The company aims to achieve carbon neutrality for its Scope 1 and Scope 2 emissions by 2050. Near-term intensity targets include a 20% reduction in combined Scope 1 and Scope 2 greenhouse gas emissions intensity across its electric arc furnace (EAF) steel mills by 2025, and a 50% reduction by 2030, both against a 2018 baseline. Furthermore, for its steel mills, the company has set a science-based emissions intensity target of 0.80 metric tonnes of CO2e per metric tonne of hot rolled steel produced by 2030, representing a 15% reduction from a 2022 baseline. A longer-term intensity target for 2050 is 0.12 metric tonnes of CO2e per metric tonne of hot rolled steel produced.
