ABSTRACT
This chapter discusses the impact of an optimized transport structure on traffic emissions reduction. A quantitative approach and panel data were used to analyze the effect of transportation structures on carbon emissions. The chapter considers the road turnover per cent, railways, waterage and civil aviation and the per unit conversion carbon dioxide turnover emissions in the transportation industry to built a fixed effect variable coefficient model. It provides a valuable reference for traffic structure optimization in China. The chapter collects data regarding passenger turnover, freight turnover and carbon emissions from China, the United States, the European Union and Japan to build a panel data model. It comparatively analyzes the impact of transport structure change on carbon emissions in the different countries. The empirical results showed that an increase in railway and waterage percentages would be helpful for carbon emissions reduction, but the degree of influence differed between the four countries.
