The GDP–CO2 Emissions Nexus in Arab Countries
This research investigates the environmental Kuznets curve (EKC) paradigm by assessing the link between real GDP per capita, renewable energy, energy prices, and carbon dioxide (CO2) emissions in selected Arab nations. In order to determine the extent of the association between the variables, the pooled mean group model is applied. According to the findings, real GDP per capita has a long-term positive effect on CO2 emissions, but quadratic GDP has a negative impact on CO2 emissions.
