CO2 emissions are the leading causes of deterioration in air quality and global warming. Likewise, it has been shown that clean energy reduces air pollution, so this would be a way out of environmental pollution. Some previous studies have focused on knowing the determinants of environmental pollution; however, they have omitted the State's role. Thus, this study explores the long-term nexus between CO2 emissions and renewable energy, energy efficiency, fossil fuels, GDP, property rights from 1995 to 2019 in nine developed countries. The results reveal a long-term equilibrium relationship in developed European countries, but not in developed non-European countries. The main results show that renewable energy and energy efficiency are negatively correlated with CO2 emissions. In developed European countries, a 1% increase in renewable energy consumption represents a 0.03% decrease in CO2 emissions. Finally, some policy measures are suggested to achieve environmental sustainability.
二氧化碳排放是空气质量恶化和全球变暖的主要原因。同样，研究表明清洁能源可减少空气污染，因此这将是解决环境污染问题的一条出路。此前一些研究着重于了解环境污染的决定因素；然而，这些研究忽略了国家的作用。因此，本研究探讨了1995年至2019年九个发达国家中二氧化碳排放与可再生能源、能源效率、化石燃料、国内生产总值、产权之间的长期联系。结果显示，在欧洲发达国家存在长期均衡关系，但在非欧洲发达国家则不然。主要结果表明，可再生能源和能源效率与二氧化碳排放呈负相关。在欧洲发达国家，可再生能源消费每增加1%，二氧化碳排放就会减少0.03%。最后，本文提出了一些实现环境可持续性的政策措施。
