How can we reduce the embodied carbon of structural concrete?

Will Arnold, Jenny Burridge, David Moore, Keerthi Ranasinghe and Sean Wilkins argue that engineers should always look to specify the most suitable material for a particular project, and offer advice on how to use materials efficiently once a choice is made.

This guidance, authored by Eugenie Sentucq and Max Clayton, details how the amount of embodied carbon in concrete can be reduced though the use of alternatives to cement.

Appendix A of Eurocode 2 permits a reduction in material partial factors for reinforcing steel and concrete. Designing elements with the reduced material partial factors reduces the amount of reinforcement steel required, hence a reduction in embodied carbon and energy, without any loss of performance.
