In 2025, Nucor 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, Nucor has not published a category-level breakdown of its Scope 3 emissions, limiting visibility into specific value chain sources.

In 2025, the total operational greenhouse gas (GHG) emissions of Nucor amounted to 12,800,000 metric tons of CO2 equivalent. This figure includes both direct emissions from owned or controlled sources (Scope 1) and indirect emissions from purchased energy (Scope 2).a
Compared to 2024, the total operational greenhouse gas (GHG) emissions of Nucor increased by 34.61%, suggesting that the company faced challenges in reducing its emissions from its core operations.ab
In 2025, the total Scope 1 emissions of Nucor were 6,600,000 metric tons of CO₂ equivalent (tCO₂e).a
Since 2019, Nucor's Scope 1 emissions have increased by 50%, reflecting a rising long-term trend in Scope 1 emissions over time.ad
Compared to the previous year (2024), Nucor's Scope 1 emissions increased by 59.47%, suggesting that the company faced challenges in reducing emissions from its directly owned or controlled operations.ab
In 2025, Nucor reported Scope 2 greenhouse gas (GHG) emissions of 6,200,000 tCO₂e without specifying the calculation method.a
In 2025, Nucor reported its Scope 2 emissions using an unspecified methodology.a
In 2025, Nucor reported 6,400,000 metric tons of CO₂ equivalent (tCO₂e) of Scope 3 greenhouse gas (GHG) emissions, representing indirect emissions across its upstream and downstream value chain.a
The 2025 disclosure of Nucor includes a breakdown across 0 of the 15 Scope 3 categories defined by the GHG Protocol, down from 1 in 2024, indicating a decline in reporting granularity and reduced insight into the company's full value chain emissions.a
In 2025, Nucor reported total Scope 3 emissions of 6,400,000 metric tons of CO₂ equivalent (tCO₂e).a
Compared to the previous year (2024), Nucor's Scope 3 emissions remained relatively stable, indicating that Nucor's emissions have plateaued with no significant change in its value chain footprint.ab
In 2025, Nucor reported Scope 1 greenhouse gas (GHG) emissions of 6,600,000 tCO₂e and total revenues of USD 32,494 millions. This translates into an emissions intensity of 203.11 tCO₂e per millions USD.a
In 2025, Nucor reported a Scope 1 emissions intensity of 203.11 tCO₂e per millions USD. Compared to the peer group median of 1,002.61, this places the company below its industry benchmark, indicating it is more carbon-efficient than most competitors.a
In 2025, Nucor ranked 6 out of 24 companies in its industry peer group, based on Scope 1 emissions intensity (measured in tCO₂e per millions USD).a
Nucor is therefore positioned in the mid-range of its industry, neither a clear leader nor a laggard in carbon efficiency.a
In 2025, Nucor reported a total carbon footprint of 19,200,000 metric tons of CO₂ equivalent (tCO₂e) across Scope 1, Scope 2, and Scope 3 emissions. This represents a 19.69% increase compared to 2024, suggesting a rise in emissions across its operations or value chain.ab
The largest contributor to Nucor's total carbon footprint was Scope 1 emissions, accounting for 34.38% of the company's total carbon footprint, followed by Scope 3 emissions at 33.33%.a
