Efficient energy is crucial in reducing CO2 emissions. The researchers are digging for a new efficient source of energy in the modern era. Therefore, this study explores the dynamic impacts of energy efficiency and renewable energy consumption on CO2 emissions from 1991 to 2019 for China. By using the non-linear ARDL approach, we found that a negative shock in energy efficiency has a positive impact on CO2 emissions in long run. Furthermore, renewable energy consumption with positive shock has a negative significant impact on CO2 emissions, but negative shock in renewable energy consumption leads to increase pollution emissions in long run. Besides, positive shocks to energy efficiency and renewable energy consumption have also a favorable negative effect on CO2 emissions in the short run. While a negative shock in energy efficiency has only unobservable negative impacts on CO2 emissions in the short run. Based on findings, some policy measures are suggested to attain environmental sustainability in China.
提高能源效率对于减少二氧化碳排放至关重要。研究人员正在现代社会中寻找新的高效能源。因此，本研究旨在探讨 1991 年至 2019 年期间能源效率和可再生能源消费对中国二氧化碳排放的动态影响。通过使用非线性 ARDL 方法，我们发现能源效率的负冲击会对长期的二氧化碳排放产生积极影响。此外，可再生能源消费的正冲击对二氧化碳排放有显著的负面影响，但可再生能源消费的负冲击会导致长期污染排放的增加。此外，能源效率和可再生能源消费的正冲击也会对短期的二氧化碳排放产生有利的负面影响。而能源效率的负冲击对短期的二氧化碳排放只有不可观测的负面影响。基于这些发现，我们提出了一些政策措施，以实现中国的环境可持续性。
