Abstract

In today’s world, where urbanization is at its pinnacle, has created a significant economic gap between rural and urban populations in developing economies and substantially influenced environmental degradation. This study investigates the relationship between urbanization and environmental degradation via carbon emissions among developing countries along the Belt and Road route from 1990 to 2019 while using economic production, energy consumption, and trade openness as control variables. The study engages current econometric methodologies to uncover accurate and reliable findings, and the outcomes reveal that the panel under investigation is cross-sectionally dependent and heterogeneous. Therefore, the AMG, CCEMG, and DCCEMG estimators are employed to examine the effect connection between the variables. The outcomes unveil that urbanization, economic production, and energy consumption escalate environmental degradation, but trade openness is confirmed as a trivial determinant of environmental degradation. Furthermore, the causal connections between the variables disclose bi-directional causalities between urbanization and environmental degradation and between energy consumption and environmental degradation. Nevertheless, uni-directional causalities are affirmed, spanning from economic production to environmental degradation and from trade openness to environmental degradation. Finally, policy implications are discussed.
