| dc.description.abstract | The demand for transportation, driven by an increasing global population, is continuously rising.
This has led to a higher number of vehicles on the road and an increased reliance on fossil
fuels. Consequently, the rise in atmospheric carbon dioxide (𝐶𝑂2) levels has contributed to
global warming. Therefore, it is important to consider sustainable transportation practices to
meet climate change mitigation targets. In this research paper, a non-linear mathematical model
is developed to study the dynamics of atmospheric 𝐶𝑂2 concentration in relation to human
population, economic activities, forest biomass, and vehicle population. The developed model
is analyzed qualitatively to understand the long-term behavior of the system’s dynamics. Model
parameters are fitted to actual data of world population, human economic activities, atmospheric
𝐶𝑂2, forest biomass, and vehicle population. It is shown that increased vehicular 𝐶𝑂2 emissions
have a potential contribution to the increase in atmospheric 𝐶𝑂2 and the decline of human
population. Numerical simulations are carried out to verify the analytical findings and we
performed global sensitivity analysis to explore the impacts of different sensitive parameters on
the 𝐶𝑂2 dynamics. | en_US |
