The developing world is facing pivotal challenges in recent times. Among these, global warming has ominous repercussions on every segment of society, thus tracing its underlying causes is imperative. This research attempts to investigate the impact of urbanization and energy consumption on carbon dioxide emissions (CO2) for a panel of 8 Asian countries (Bangladesh, China, India, Indonesia, Malaysia, Nepal, Pakistan, and Sri Lanka) over the period 1982 to 2017. The analyses are executed using panel co-integration and Granger causality techniques. The main findings of panel co-integration reveal a long-run relationship between urbanization, energy consumption, and CO emissions. Furthermore, the results indicate a positive and significant impact of urbanization and energy consumption on CO emissions, indicating that urban development and high energy consumptions are barriers to improve environmental quality in the long run. The results also highlight bi-directional causality between energy consumption and urbanization, while unidirectional causality exists between energy consumption and CO emissions. Based on the obtained results, this study offers useful policy implications for plummeting carbon emissions.
发展中国家正面临着近年来的重大挑战。其中，全球变暖对社会的各个阶层都产生了不祥的影响，因此，追溯其根本原因势在必行。本研究旨在调查城市化和能源消耗对二氧化碳（CO2）排放的影响，选取了 1982 年至 2017 年期间的 8 个亚洲国家（孟加拉国、中国、印度、印度尼西亚、马来西亚、尼泊尔、巴基斯坦和斯里兰卡）作为研究对象。该研究采用面板协整和格兰杰因果关系技术进行分析。面板协整的主要结果表明，城市化、能源消耗和 CO 排放之间存在长期关系。此外，结果还表明城市化和能源消耗对 CO 排放有正向和显著的影响，这表明城市发展和高能源消耗从长远来看是改善环境质量的障碍。结果还强调了能源消耗和城市化之间存在双向因果关系，而能源消耗和 CO 排放之间存在单向因果关系。基于研究结果，本研究为降低碳排放提供了有益的政策建议。
