Interaction between transport activity and CO2 emissions: The need for a sustainable transport policy

The issue of greenhouse gas emissions from human activities occupies an important place. Due to its reliance on internal combustion engine technology, the transport sector is one of the largest emitters of greenhouse gases (GHGs) in most countries. Our work is part of this context where we asked several questions about the external effects of transport and in particular about the nature of the relationship between transport and the CO2 emissions. In other words, we first identified the nature of the relationship between the two series for the Tunisian case. Secondly, we focused on the analysis of transport sector variables based on the intensities decomposition methods commonly used in the research, and we completed the work with interpretations and lessons that aim for a sustainable vision of transport in Tunisia.
