This study investigates the impact of urbanization and nonrenewable energy consumption on carbon emissions. The context of the analysis is 54 African Union countries from 1996 to 2019. For estimation, we use panel quantile regression (PQR) and fully modified ordinary least squares (FMOLS). Our regression results demonstrate that there is a positive correlation between urbanization and CO emission. Further, our empirical results confirmed that nonrenewable energy consumption increases environmental pollution in African Union countries. The outcomes demonstrate the EKC hypothesis because at the initial stage of development, when economic growth increases, environmental pollution increases; after a threshold point, environmental pollution decreases as economic growth increases. It can find an inverted U-shaped relationship between economic growth and CO emission. The findings also show that urbanization should be planned; otherwise, it can lead to environmental degradation in the long run. Africa continent takes strict action and builds a blueprint for efficient and effective energy production and consumption. The only solution to achieve green growth in Africa is to shift from fossil fuel energy supply to renewable energy supply.
本研究考察了城市化和不可再生能源消费对碳排放的影响。分析的背景是 1996 年至 2019 年的 54 个非洲联盟国家。为了进行估计,我们使用了面板分位数回归(PQR)和全修正最小二乘法(FMOLS)。我们的回归结果表明,城市化与 CO 排放之间存在正相关关系。此外,我们的实证结果证实,不可再生能源消费增加了非洲联盟国家的环境污染。结果表明存在环境库兹涅茨曲线假说,因为在发展的初始阶段,随着经济增长,环境污染增加;超过一个门槛值后,随着经济增长,环境污染会减少。经济增长与 CO 排放之间存在着倒 U 型关系。研究结果还表明,城市化应该进行规划;否则,从长远来看,城市化可能会导致环境恶化。非洲大陆采取严格的行动,为高效和有效的能源生产和消费制定蓝图。实现非洲绿色增长的唯一解决方案是将能源供应从化石燃料转向可再生能源。
