Material selection and design approach have a major impact on the embodied carbon of bridge structures.
This paper compares different bridge construction methods to identify which options deliver the lowest carbon outcomes. It highlights how structural form and material efficiency influence overall emissions, not just material choice alone.
The findings reinforce the importance of early design decisions in reducing embodied carbon and improving sustainability outcomes across infrastructure projects.
The comparisons show the benefits of high strength reinforcing steel over conventional 500 MPa steels in terms of achieving carbon reductions.
