One of the greatest challenges facing humanity in the current millennium is the need to mitigate climate change, and one of the most viable options to overcome this challenge is to invest in renewable energy. The study dynamically examines the links between renewable energy consumption, non-renewable energy consumption, climate change, and economic growth in five emerging Asian countries during the period 1975-2020. Variables selected in the model have long-term cointegration, as explored by the Pedroni cointegration test and the Westerlund cointegration test. The long-term estimated parameters of the augmented mean group (AMG) method show that renewable energy consumption significantly reduces climate change, while non-renewable energy consumption significantly promotes climate change. The results also show that GDP, investment in transport infrastructure, and urbanization can significantly contribute to climate change in selected emerging Asian countries. Moreover, the results validate the inverted U-shaped EKC hypothesis for emerging Asian economies. Country-specific analysis results using AMG estimates shows that renewable energy consumption reduces climate change in selected emerging Asian countries. Non-renewable energy consumption and investment in transport infrastructure have had significant progressive impacts on climate change in all countries. Urbanization contributes significantly to climate change, with the exception of Japan, which does not have any significant impact on climate change. GDP contributes significantly to climate change in all countries; however, GDP2 has significant adverse effects on climate change in India, China, Japan, and Korea, validating the inverted U-shaped EKC assumption for all countries except Bangladesh. Moreover, the Dumitrescu and Hurlin causality test confirmed a pairwise causal relationship between non-renewable energy consumption and GDP, supporting the feedback hypothesis. The results suggest that the best option for climate change mitigation in selected emerging Asian countries is to transition from non-renewable to renewable energy sources.
当前千年人类面临的最大挑战之一是需要减轻气候变化，而克服这一挑战最可行的选择之一是投资于可再生能源。本研究在 1975 年至 2020 年期间，动态地考察了五个亚洲新兴国家可再生能源消费、不可再生能源消费、气候变化和经济增长之间的关系。通过 Pedroni 协整检验和 Westerlund 协整检验，模型中选择的变量具有长期协整关系。增强型均值组（AMG）方法的长期估计参数表明，可再生能源消费显著减少了气候变化，而不可再生能源消费则显著促进了气候变化。结果还表明，在选定的亚洲新兴国家中，国内生产总值、交通运输基础设施投资和城市化进程可以显著促进气候变化。此外，结果验证了亚洲新兴经济体的倒 U 型 EKC 假说。使用 AMG 估计值的国家特定分析结果表明，可再生能源消费减少了选定亚洲新兴国家的气候变化。不可再生能源消费和交通运输基础设施投资对所有国家的气候变化都产生了显著的累进影响。城市化进程对气候变化有显著贡献，但日本除外，日本对气候变化没有任何显著影响。国内生产总值对所有国家的气候变化都有显著贡献；然而，国内生产总值 2 对印度、中国、日本和韩国的气候变化产生了显著的不利影响，验证了除孟加拉国以外所有国家的倒 U 型 EKC 假设。此外，Dumitrescu 和 Hurlin 因果检验证实了不可再生能源消费和 GDP 之间的两两因果关系，支持反馈假设。结果表明，在选定的亚洲新兴国家中，缓解气候变化的最佳选择是从不可再生能源向可再生能源过渡。
