This study contributes to the growing but still limited body of literature on the impact of economic policy uncertainty, renewable energy usage, and economic growth on environmental degradation in Egypt. Using the autoregressive distributed lag (ARDL) bound test, we examine the existence of cointegration relationships in Egypt over the period 1990-2018. Our results indicate that economic policy uncertainty is positively associated with environmental degradation in both the short and long run. Additionally, we find that economic growth exacerbates environmental degradation in both the short and long term. Finally, renewable energy consumption has a significant negative effect on environmental degradation in the long run. Therefore, ensuring economic policy stability is crucial for maintaining environmental quality. To this end, Egyptian policymakers should prioritize low-carbon research and development techniques, as well as the adoption of renewable energy sources to mitigate environmental degradation.
这项研究为不断增长但仍然有限的关于经济政策不确定性、可再生能源使用以及经济增长对埃及环境恶化影响的文献做出了贡献。本研究使用自回归分布滞后（ARDL）边界检验，检验了 1990-2018 年埃及是否存在协整关系。研究结果表明，经济政策不确定性在短期和长期内都与环境恶化呈正相关。此外，我们发现经济增长在短期和长期内都加剧了环境恶化。最后，可再生能源消费在长期内对环境恶化有显著的负向影响。因此，确保经济政策的稳定性对于维护环境质量至关重要。为此，埃及政策制定者应优先考虑低碳研发技术以及采用可再生能源来减轻环境恶化。
