123 Forum: Do Building Codes and Standards Support Sustainable Development? (ACI Fall 2022, Dallas, TX) Cement is typically the largest individual contribution to the embodied global warming potential (CO2-equivalent) of a concrete mixture. The cement industry has developed roadmaps to reaching carbon neutral concrete by mid-century, both for the US and globally. This presentation will identify how cement and cementitious materials are expected to evolve in the roadmaps and discuss how effective updates to codes and standards can help to accelerate the achievement of carbon neutral concrete.
