In response to the lack of evaluation standards for low carbon ports,taking green,energy-saving,carbon reduction and pollution reduction as the basic starting point,based on the P-S-R model,the Analytic Hierarchy Process and Delphi method are used to create an index system for low-carbon port evaluation,which includes 7 primary indexes and 21 secondary indexes,including carbon emission indexes,energy activity indexes,water resources indexes,green building indexes,green electricity indexes,environmental carbon sink indexes,and management system indexes.The index system adopts a combination of quantitative and qualitative indexes,which has good systematicity,scientificity,port characteristics,strong operability,and good synergy in reducing carbon emissions in ports.This paper also puts forward a method and judgment criteria for assigning evaluation indexes for low-carbon ports,and provides benchmark values of evaluation indexes based on normative standards,industry development plans,management regulations,and port statistical data over the years.The research results provide a complete and scientific evaluation basis for the creation of low-carbon ports,and have good application prospects.
