The presenters engaged in research with company funding over the course of a year to explore sources of embodied carbon in structural steel and how to meaningfully reduce the global warming potential inherent in steel designs. Through several iterations of inquiry with industry representatives (fabricators, producers) and experts (steel production analysts), and after investigating the potential of various digital tool concepts, the presenters ultimately discovered that a best practices primer series on the subject for structural engineers and architects may be the most effective way to influence a widespread effort to meaningfully decrease the embodied carbon of structural steel projects. The information that became the focus of the primer series resulted from interviews that the speakers conducted with major steel industry professionals, and from in-depth research into the energy involved in the steel manufacturing process. This presentation will discuss the reasons that the previous iterations were not ultimately judged to be effective vehicles to meaningful embodied carbon reduction, and the reasons the current primer series publication can have a meaningful and widespread impact on reduction of structural steel’s global warming potential. Finally, the presenters will explain the use of the primer series.
