4、Alignment in the Built EnvironmentExecutive Summary4A Path to Alignment in the Built EnvironmentExecutive SummaryTo decarbonize buildings across their full life cycle,it is imperative to enable carbon optimization during the decision-making process and to be able to conduct whole life carbon(WLC)ana

5、lysis in a standardized,transparent and consistent way.Driven by this imperative to enable better workflows for WLC analysis,WBCSD,Autodesk and six architecture,engineering and construction(AEC)firms collaborated on a proof of concept(PoC).The PoC used the same building information model(BIM)to do a

6、n in-depth embodied carbon assessment.The initiative aimed to explore BIM methods,BIM workflows and bill of material(BOM)analysis processes to identify alignment and differences in carbon assessment practices.The goal of this discovery exercise was to establish best practices for potential industry-
