The primary objective of this study is to explore the links between fossil fuel energy consumption, industrial value-added, and carbon emissions in G20 countries over the period 1990-2020. Panel unit root test, co-integration test, and CS-ARDL estimator were used to determine the relationship among variables. The empirical results suggest that the driving force of carbon emissions in G20 countries varies significantly in advanced versus emerging economies. Evidence in a whole sample of G20 countries and advanced economies supports environmental Kuznets curve (EKC) hypothesis, while no evidence emerging economies supports EKC hypothesis. Apart from this, the empirical results show trade opens, FDI, government expenditures on health and education, research and development, and information and communication technology are other determinators of carbon emissions in G20 countries. Our results suggest that countries upgrade industrial structures by shifting their energy structures away from fossil fuels toward renewable energy sources in order to achieve sustainable environmental goals.
本研究的主要目的是探讨 1990-2020 年间 G20 国家化石燃料能源消费、工业增加值和碳排放之间的联系。使用面板单位根检验、协整检验和 CS-ARDL 估计器来确定变量之间的关系。实证结果表明，G20 国家的碳排放驱动力在发达经济体和新兴经济体之间存在显著差异。在 G20 国家的全样本和发达经济体的证据支持环境库兹涅茨曲线（EKC）假说，而新兴经济体的证据则不支持 EKC 假说。除此之外，实证结果还表明，贸易开放、外国直接投资、卫生和教育支出、研发以及信息和通信技术是 G20 国家碳排放的其他决定因素。我们的结果表明，各国应通过将能源结构从化石燃料转向可再生能源来升级产业结构，以实现可持续的环境目标。
