Cmc

In 2025, Cmc's total reported emissions were approximately 4.31 billion kg CO2e. This included Scope 1 emissions of about 1.15 billion kg CO2e, Scope 2 emissions of around 1.25 billion kg CO2e, and Scope 3 emissions of roughly 1.91 billion kg CO2e.

Looking back, Cmc's total emissions were approximately 3.87 billion kg CO2e in 2024, about 3.68 billion kg CO2e in 2023, and roughly 3.83 billion kg CO2e in 2022.

Cmc has established several climate commitments. The company aims to reduce its Scope 1 and Scope 2 emissions intensity by 20% by 2030, using a 2019 baseline. Furthermore, Cmc is focused on increasing its renewable energy usage by 12 percentage points and reducing its consumption intensity by 5% by 2030, also against a 2019 baseline. A long-term ambition for Cmc is to achieve net-zero emissions by 2050 for Scope 1 and Scope 2 emissions.

Historically, Cmc also had a goal to reduce its absolute energy use (Scope 1 and Scope 2) by 25% by 2023, based on a 2012 baseline, through participation in the U.S. Department of Energy’s Better Buildings, Better Plants Initiative.
