Environmental degradation is significantly studied both in the past and the current literature; however, steps towards reducing the environmental pollution in carbon emission and haze pollution like PM2.5 are not under rational attention. This study tries to cover this gap while considering the carbon emission and PM2.5 through observing the role of renewable energy, non-renewable energy, environmental taxes, and ecological innovation for the top Asian economies from 1990 to 2017. For analysis purposes, this research considers cross-sectional dependence analysis, unit root test with and without structural break (Pesaran, 2007), slope heterogeneity analysis, Westerlund and Edgerton (2008) panel cointegration analysis, Banerjee and Carrion-i-Silvestre (2017) cointegration analysis, long-short run CS-ARDL results, as well as AMG and CCEMG for robustness check. The empirical evidence in both the short- and long-run has confirmed the negative and significant effect of renewable energy sources, ecological innovation, and environmental taxes on carbon emissions and PM2.5. Whereas, non-renewable energy sources are causing environmental degradation in the targeted economies. Finally, various policy implications related to carbon emission and haze pollution like PM2.5 are also provided to control their harmful effect on the natural environment.

过去和现在的文献都对环境退化进行了大量研究；然而，减少碳排放和PM2.5等雾霾污染等环境污染的举措并未受到理性关注。本研究试图通过观察 1990 年至 2017 年亚洲主要经济体的可再生能源、不可再生能源、环境税和生态创新的作用，在考虑碳排放和 PM2.5 的同时弥补这一差距。研究考虑了横截面相关性分析、有和没有结构断裂的单位根检验 (Pesaran, 2007)、坡度异质性分析、Westerlund 和 Edgerton (2008) 面板协整分析、Banerjee 和 Carrion-i-Silvestre (2017) 协整分析、长期-短期CS-ARDL结果，以及用于稳健性检查的 AMG 和 CCEMG。短期和长期的经验证据都证实了可再生能源、生态创新和环境税对碳排放和 PM2.5 的负面和显着影响。然而，不可再生能源正在导致目标经济体的环境恶化。最后，还提供了与碳排放和雾霾污染（如 PM2.5）相关的各种政策含义，以控制其对自然环境的有害影响。
