After the Paris Climate Conference (Conference of the Paris COP: 21), many countries started progressing towards carbon neutrality. In doing so, the present study aims to assess the role of eco-innovation and globalization in mitigating CO2 emissions in the case of the USA. The study applied Quantile Autoregressive Distributed Lag (QARDL) approach to estimate the short-run and long-run relationship among the selected variables. According to the empirical results, gross domestic product (GDP) positively influences the level of CO2 emissions for the USA economy at all quantiles. However, GDP square is negatively associated with CO2 emissions in the USA; therefore, our study supports the existence of EKC for the USA. Further, eco-innovation is the mitigating factor of CO2 emissions in our empirical analysis. Our study proved that globalization is the stimulating factor of CO2 emissions in the US economy. The empirical estimates of the Granger causality test show the bidirectional causality from GDP, eco-innovations, and globalization to GDP for the USA economy. To mitigate CO2 emissions, the study provides useful insights for policymakers in the USA economy.
巴黎气候大会(巴黎第21届缔约方会议)之后,许多国家开始朝着碳中和迈进。在此背景下,本研究旨在评估生态创新和全球化在美国减少二氧化碳排放方面的作用。该研究采用分位数自回归分布滞后(QARDL)方法来估计所选变量之间的短期和长期关系。根据实证结果,国内生产总值(GDP)在所有分位数上均对美国经济的二氧化碳排放水平产生正向影响。然而,GDP的平方与美国的二氧化碳排放呈负相关;因此,我们的研究支持美国存在环境库兹涅茨曲线(EKC)。此外,在我们的实证分析中,生态创新是二氧化碳排放的缓解因素。我们的研究证明,全球化是美国经济中二氧化碳排放的刺激因素。格兰杰因果检验的实证估计表明,对于美国经济,存在从GDP、生态创新和全球化到GDP的双向因果关系。为减少二氧化碳排放,该研究为美国经济的政策制定者提供了有益的见解。
