A systematic review on carbon emission of light duty vehicles in urban environment

Human activities releasing greenhouse gases have been the main cause of climate change since the mid-20th century. The issue of integrated land use-transport planning lacks sufficient studies. Furthermore, due to the continuous process of urbanization, there has been a substantial rise in both the urban population and the amount of developed land. Urban land use and transport planning are key to efficient reduction of light-duty private vehicles' emissions and promoting sustainable cities. This Systematic Literature Review complies with the requirements established by ROSES. The research investigates three main themes by utilizing 14 articles: firstly, it analyzes the magnitude and repercussions of carbon emissions from light-duty private vehicles, emphasizing their contribution to environmental concerns such as climate change. Secondly, the study assesses a broader spectrum of pollutants released by light-duty private vehicles, surpassing carbon dioxide, thereby tackling the complex issues presented by vehicle pollution in metropolitan regions. Finally, it examines the magnitude of carbon emissions produced by light-duty private vehicles. The studies’ compilation highlights the immediate necessity to thoroughly evaluate the environmental effects of light-duty private vehicles in urban settings. Establishing effective regulations and strategies to reduce emissions and promote sustainable urban transportation is crucially required.
