Based on the urban planning and design concept of “small block, dense road network”, the paper analyzes the cases of low-carbon transportation-oriented road network planning and construction in the Netherlands,and summarizes the design concept and implementation method of road network planning of public transportation and slow traffic friendly blocks. The successful experiences of low-carbon transportationoriented city construction in the Netherlands are summarized, in order to provide the reference for lowcarbon urban development in China.展开更多

At the same time, it is the only industry in China that has continuously increased CO2 emissions, and the high energy consumption problems have not been solved. Henan province, as a major energy consumption province, it is urgent to improve the supply quality of transportation industry. The paper uses the IPCC calculation method for carbon emission to calculate the CO2 emissions of transportation industry in Henan province from 2004 to 2014. Then, this paper uses the LMDI method to decompose the CO2 emission in the transportation industry and give the proposal to reduce the CO2 emission according to the CO2 emission drivers.展开更多

The logistic industry plays a key role in the economic development, which influences emission and impact of the theory of low carbon. This paper analyzes the energy consumption and carbon emission in different modes in transportation, and provides reasonable suggestions on low carbon and reduction emission for transportation industry in China.展开更多
