In this paper, we investigate the impact of energy use and economic policy uncertainties on the environment. To achieve this objective, we use the pooled mean group-autoregressive distributed lag methodology (PMG-ARDL) and Dumitrescu and Hurlin causality test on 22 Organisation for Economic Co-operation and Development (OECD) countries between 1985 and 2017. The PMG-ARDL estimation shows that energy use and economic policy uncertainties have a positive relationship with carbon dioxide emission (CO) emission, while a negative relationship is confirmed between renewable and CO emissions in the long run. The short-run estimation shows a positive relationship between energy use, real gross domestic product, and per capita on CO emissions. The Dumitrescu and Hurlin causality results highlight a unidirectional running from real GDP and GDP per capita square to CO emissions. Furthermore, one-way causality exists between CO emissions to economic policy uncertainties. These results have policy implications on the macroeconomy which are discussed in detail in the concluding section.
在本文中，我们研究了能源使用和经济政策不确定性对环境的影响。为了实现这一目标，我们使用了 1985 年至 2017 年间 22 个经济合作与发展组织（OECD）国家的面板均值群自回归分布滞后法（PMG-ARDL）和 Dumitrescu 和 Hurlin 因果关系检验。PMG-ARDL 估计结果表明，能源使用和经济政策不确定性与二氧化碳排放（CO）排放呈正相关，而在长期内，可再生能源和 CO 排放之间存在负相关关系。短期估计结果表明，能源使用、实际国内生产总值和人均国内生产总值与 CO 排放之间呈正相关关系。Dumitrescu 和 Hurlin 因果关系结果突出表明，从实际国内生产总值和人均国内生产总值平方到 CO 排放存在单向运行。此外，CO 排放与经济政策不确定性之间存在单向因果关系。这些结果对宏观经济具有政策意义，在结论部分进行了详细讨论。
