The carbon footprint is one of the most important environmental factors. The long span structure systems are widely employed in commercial, public and cultural buildings. The life cycle carbon emissions of long span structure systems have great impact on the environment. Embodied carbon is of significant percentage of the life cycle carbon footprint of long span structure systems. This paper addresses the analysis method of embodied carbon of long span structure systems, and proposed a new long span structure system comparative study process based on embodied carbon.Keywords: embodied carbon; long-span structure system
