Even though a great number of researches have explored the determinants of carbon emissions, the impact of economic policy uncertainty (EPU) on the environment has not been fully investigated in the energy-environment literature. Since recent studies show a strong relationship between the external environment and uncertainty, the present study for the first time in the literature aims to explore the function of EPU in the energy-environment nexus for China by using the novel bounds testing with dynamic simulations. The empirical results indicate that increases in the real income and energy intensity contribute to environmental pollution while increases in renewable energy lower the level of emissions. Besides, an increase in EPU causes an increase in the volume of carbon emissions. As EPU increases, the government's attention to implement environmental protection policies decreases, and the execution of the environment-related strategies is likely directed in an expected way. The empirical findings suggest that the government should establish consistency in economic and environmental policies to mitigate environmental pollution and thus to reach environmental sustainability.
尽管大量研究探讨了碳排放的决定因素，但在能源环境文献中，经济政策不确定性（EPU）对环境的影响尚未得到充分研究。由于最近的研究表明外部环境和不确定性之间存在很强的关系，因此本研究首次在文献中旨在通过使用新的具有动态模拟的边界检验来探索 EPU 在能源环境关系中的作用。实证结果表明，实际收入和能源强度的增加有助于环境污染，而可再生能源的增加则降低了排放水平。此外，EPU 的增加会导致碳排放量的增加。随着 EPU 的增加，政府对实施环境保护政策的关注减少，环境相关战略的执行可能会以预期的方式进行。实证结果表明，政府应该在经济和环境政策方面建立一致性，以减轻环境污染，从而实现环境可持续性。
