Measuring the low carbon performance of buildings is a crucial method for achieving construction industry's strategic goal “double carbon.” The emission factor calculation approach proposed by IPCC utilized to create model steel-concrete composite structure bridge across its whole life cycle. discount rate used determine dynamic emissions structural bridge, which are then compared static emissions. strength evaluated using fuzzy comprehensive technique. application analysis conducted on basis in Beijing. According findings, primarily concentrated during preparation, production, and operation building materials. bridge's 103.966 1378.674 ktCO 2 e, respectively. After material recovery, values 95.141 e 1107.751 ratio ranges from 7 34, highlighting significance temporal value. recycling components, dropped 2.565 2.353, while fell 2.422 2.210, both were medium strengths. this study can successfully examine bridges environmental economic perspectives, it be select more environmentally friendly materials methods increase efficiency. It also provides valuable data assistance establishment execution protection measures, thereby promoting long-term sustainable development.
