In the structural engineering of buildings, concrete and steel are among the most widely used materials. Concrete is actually the most abundant manufactured material on earth. But for all of the tremendous qualities these commonly used structural materials provide, they come with high environmental costs in the form of embodied carbon. And many structural engineers are starting to take note…and do something about it.

One such engineer is Luke Lombardi, a senior sustainability consultant at the engineering consultancy firm, Buro Happold. And at this year’s Build Reuse conference, Luke spoke about the major impact structural engineers can have on the path to net zero.

In this episode, he shares some of those insights and talks about how natural building materials fit into the picture.
