Steel Dynamics

Steel Dynamics, based in the US, is a prominent company in the basic iron and steel and ferro-alloys industry.

In 2025, Steel Dynamics reported approximately 8.55 billion kg CO2e in total emissions, comprising about 1.95 billion kg CO2e in Scope 1 emissions and about 5.23 billion kg CO2e in Scope 3 emissions.

In 2024, the company's total emissions were approximately 8.62 billion kg CO2e. This included roughly 2.85 billion kg CO2e from Scope 1, about 1.63 billion kg CO2e from Scope 2 (market-based), and approximately 5.52 billion kg CO2e from Scope 3 emissions. Within Scope 3, purchased goods and services accounted for about 4.85 billion kg CO2e, fuel and energy-related activities for roughly 924.67 million kg CO2e, upstream transportation and distribution for approximately 505.81 million kg CO2e, and downstream transportation and distribution for about 72.07 million kg CO2e.

Looking back to 2023, Steel Dynamics' Scope 1 emissions were approximately 2.75 billion kg CO2e, with Scope 2 market-based emissions at about 2.31 billion kg CO2e. Scope 3 emissions included roughly 4.58 billion kg CO2e from purchased goods and services, about 973.66 million kg CO2e from fuel and energy-related activities, approximately 696.52 million kg CO2e from upstream transportation and distribution, and about 106.08 million kg CO2e from downstream transportation and distribution.

The company has set ambitious climate commitments, aiming for carbon neutrality by 2050 for Scope 1 and Scope 2 emissions. Steel Dynamics is targeting a 20% reduction in combined Scope 1 and Scope 2 greenhouse gas emissions intensity across its EAF steel mills by 2025, against a 2018 baseline. This reduction target increases to 50% by 2030, also compared to the 2018 baseline. Additionally, Steel Dynamics announced certified, science-based GHG emissions intensity targets for its steel mills. In alignment with the 1.5°C scenario of the Paris Agreement, the company aims for a 2050 emissions intensity target of 0.12 metric tonnes of CO2e per metric tonne of hot rolled steel produced. An interim 2030 emissions intensity target is set at 0.80 metric tonnes of CO2e per metric tonne of hot rolled steel produced, representing a 15% reduction from its 2022 baseline.
