Abstract

CO2 reduction from transportation is exerting significant effects on global CO2 reduction. This industry contributes 23.96% of global CO2 emissions. In this research, an ecological network input–output interval fuzzy linear programming (EIFP) method is developed to clarify CO2 reduction responsibilities and depict transfer relationships of transportation. This method integrates input–output analysis (IOA), inexact rough interval fuzzy linear programming (IRFLP) and ecological network analysis (ENA) into a general framework. The proposed method is employed for calculating inter-provincial CO2 transfer under different situations in 30 provinces of China and further supporting the formulation of regional reduction policies. Results demonstrate that transportation energy demand of Beijing is dependent on imports, which indirectly increases CO2 reduction pressure in energy supply areas. Therefore, CO2 reduction responsibility should be traced to source and included in emission reduction plan of energy demand areas. In inter-provincial CO2 transfer relationships of natural gas, positive relationships account for a higher proportion; therefore, it is feasible to consider raising the proportion of natural gas in the future development direction of transportation. The achievements of this paper can provide scientific references for decision makers to formulate CO2 reduction policies in transportation.

Highlights

Clarifying CO2 reduction responsibility of transportation is of considerable significance to global climate change and completing global CO2 reduction objectives
In the fuel type composition in FY 2017, gasoline contained in fuel oil took up the largest share (54%), followed by light oil (26%) and electricity consumed by railroad (11%)
The main transfer of CO2 emissions occurred in East China (EC) (i.e., 563.20 thousand tons), and the smallest transfer occurred in North China (NC)

Summary

Introduction

Clarifying CO2 reduction responsibility of transportation is of considerable significance to global climate change and completing global CO2 reduction objectives. CO2 emissions of transportation take a large proportion in numerous regions of the world. The largest sources of transportation-related CO2 emissions include passenger cars, mediumand heavy-duty trucks, and light-duty trucks, including sport utility vehicles, pickup trucks, and minivans. These sources account for over half of the emissions from transportation. It was estimated that by 2018, U.S transportation would attain 28% of CO2 emissions, surpassing the power sector (27%) and developing into the largest CO2 emissions in the United States [1]. As of 2018, CO2 emissions from transportation rose to
