Research on identifying main factors affecting building carbon reaching the peak based on DEMATEL-ISM method

This paper takes the influencing factors of peaking building carbon dioxide emissions as the research object, finds out 14 factors from 7 main bodies, including material suppliers, design units, owners, construction units, customers, governments and society and then analyzes the influencing factors of achieving the goal of carbon peak and carbon neutralization by using triangular fuzzy number, DEMATEL(Decision Making Trial and Evaluation Laboratory)and ISM (Interpreting structural models)methods. The results show that the formulation of relevant policies and regulations is the essential cause of peaking building carbon dioxide emissions; Low-carbon building materials, green logistics, green structure, low carbon energy consumption, low carbon construction party and contractor selection, low carbon operation, and low carbon technology innovation are the surface causes. The three factors that have a great impact on the target are consumer preference, formulation of relevant policies and regulations, and green building indicators. Finally, according to the research results, suggestions are put forward to achieve the goal of peaking building carbon dioxide emissions.
