Carbon reduction is an important issue of global concern today, and with the construction industry accounting for a significant portion of global carbon emissions, carbon reduction research for the civil engineering industry is becoming increasingly important. The current research on carbon emission of buildings mainly focus on energy consumption, choice of building materials, and energy‐saving technologies. While different construction programs can affect the construction sequence and have a significant impact on carbon emissions, especially for ultra‐high‐rise steel structures. In this paper, carbon emission is introduced as the optimization objective, and a nodal optimization procedure based on carbon emission is given to explore the optimization scheme of ultra‐high‐rise steel structure construction based on carbon emission. Calculations using the carbon emission factor method were carried out to analyze the differences in carbon emissions between different construction schemes and to explore the impact of the method of carbon emission optimization. Results show that the combined lifting scheme can save 463.4 kg carbon emissions and reduce the number of lifts by 780 times.
