Nucor

Nucor, a US-based company in the Basic iron and steel and of ferro-alloys and first products thereof industry, has reported its carbon emissions and climate commitments.

For 2025, Nucor projects Scope 1 emissions of approximately 4.64 billion kg CO2e, Scope 2 market-based emissions of about 5.43 billion kg CO2e, and Scope 3 emissions (specifically from purchased goods and services) of roughly 7.58 billion kg CO2e.

In 2024, the company reported total emissions of approximately 18 billion kg CO2e. This included about 4.14 billion kg CO2e for Scope 1 emissions, roughly 5.10 billion kg CO2e for market-based Scope 2 emissions (or about 5.37 billion kg CO2e location-based Scope 2 emissions), and approximately 6.53 billion kg CO2e for Scope 3 emissions, specifically from purchased goods and services.

For 2023, Nucor disclosed Scope 1 emissions of approximately 6.8 billion kg CO2e and Scope 3 emissions of around 8.3 billion kg CO2e. Scope 2 data was not disclosed for this year. In 2022, only Scope 1 emissions were reported, amounting to approximately 6.5 billion kg CO2e.

Looking back to 2021, Nucor's total emissions were approximately 20.1 billion kg CO2e, comprising roughly 7.1 billion kg CO2e for Scope 1, about 5.7 billion kg CO2e for Scope 2, and approximately 7.3 billion kg CO2e for Scope 3.

In 2020, total emissions were around 17.5 billion kg CO2e, with Scope 1 emissions at approximately 4.7 billion kg CO2e, Scope 2 emissions at roughly 5.4 billion kg CO2e, and Scope 3 emissions at about 7.4 billion kg CO2e.

For 2019, Nucor reported Scope 1 emissions of approximately 4.39 billion kg CO2e, and in 2018, Scope 1 emissions were around 4.83 billion kg CO2e. In 2017, Scope 1 emissions stood at approximately 4.37 billion kg CO2e. No emissions data was disclosed for 2016 or 2015.

Nucor has set several climate commitments:

• A near-term intensity target to achieve a 35% combined reduction in steel mill Scope 1 and Scope 2 GHG intensity by 2030, using a 2015 baseline. This commitment was made in 2020.
• Separate near-term absolute targets to reduce Scope 1 emissions by 30% and Scope 2 emissions by 30% from a 2020 baseline by 2030.
• A long-term net-zero commitment towards reducing steel mill carbon intensity beyond 2030.
• An aim to reduce its Scope 1 and Scope 2 emissions to near-zero by the middle of the current decade (by 2025).
• A long-term net-zero target for 2050 covering Scope 1, 2, and 3 emissions, based on the emission standard developed by the Global Steel Climate Council (GSCC), which Nucor helped to establish.
