Abstract
Shifting toward sustainable daily travel will play a significant role in the future of sustainable development and the lowering of carbon emissions. This study provides an in-depth comparison of transport mode choice and corresponding CO2 emissions between private cars and public transport used for shopping trips based on individual data from a travel survey conducted in Shenyang, China. The analysis found that bus travel accounted for the majority of motorized transportation. Public transport users were closely distributed along the bus or metro lines, and aggregated private car users were mainly clustered within the second circumferential road. Furthermore, average per trip emissions for private car travel were 8-fold that of public transport. Binary logistic regression modeling was employed to examine factors that were related to the choice between private car and public transport, and the results indicated that car ownership and gender were the most important factors in explaining the preference of car driving. Age and per capita monthly income were negatively correlated with car driving. In addition, there were also negative impacts associated to the built environment factors of access to the closest metro stations and the number of bus stops near the residence on car driving. This study is vital to formulate more effective transportation policy measures in the future development for a sustainable low-carbon city.

Summary
The contributions of transportation development to the sustainability of cities has been widely recognized by various scholars throughout the world [1, 2]. Urban passenger transport has received increasing concern for its impact on energy consumption, urban pollution and public health and is the area where the most effective carbon mitigation could be made, which is perceived as playing a key role in sustainable development [10, 11]. With rapid economic growth and increasing urbanization, there is a rapidly surging trend of automobilization, private vehicles, significantly exerting tremendous pressure on energy consumption and environmental emissions in China [12]. According to the China Statistical Yearbook, private passenger cars increased from 10.80 million in 2005 to 146.46 million in 2016, which is a nearly 14-fold increase This trend has led to a widespread use of private transport and rising greenhouse gas emissions from urban mobility in Chinese cities experiencing rapid urbanization and expansion [13]. Travel mode choice behavior in residents’ daily travel plays a crucial role in the future development of urban regions [17]
