What is low embodied carbon steel?

 

Low embodied carbon steel refers to steel produced with reduced greenhouse gas emissions across its lifecycle, including raw material sourcing, manufacturing, and delivery.

 

By incorporating higher recycled content, cleaner energy sources, and advanced production technologies, it offers a more sustainable option for modern projects. Choosing low embodied carbon steel supports environmental goals, helps lower overall project emissions, and contributes to more responsible building practices.
