An autoregressive distributed lag (ARDL) econometric technique different diagnostic tests are used to investigate linkages. The pairwise Graner causality approach is applied direction. estimated results have confirmed that energy urbanization reduce emissions, whereas openness induces long run findings revealed non-existence of environmental Kuznets curve (EKC) hypothesis In contrast, pollution haven (PHH) exists between Regarding causal relationships, there bi-directional urbanization. reports a unidirectional from CO2 development trade. Based on above findings, this recommends some policy recommendations.
