By retaining heat in the atmosphere, pollution from the transport industry plays an indispensable role in climate change. In order to reduce transportation-related emissions, employing electric vehicles (EVs) offers an economical solution for attaining emission-free road mobility. In this context, the present study revisits the Environmental Kuznets Curve (EKC) and evaluates the consequences of EVs, innovations in environment-related technologies and renewable energy on the environment. To accomplish this, the study analyzed panel data from 38 economies covering the period 2013-2023, using the system GMM technique. The results demonstrate that employing EVs, renewable energy sources, and environmental technology are each significantly associated with reductions in carbon emissions. Specifically, a one-unit increase in EV adoption is linked to a decrease in carbon dioxide emissions by approximately 0.00000732 units, whereas renewable energy and environmental technology reduce emissions by 0.0005975 and 0.0548603 units, respectively. The findings support an N-shaped relationship between economic growth and CO emissions and a U-shaped link between innovations in environment-related technologies and CO emissions. To reduce emissions associated with transportation, this study suggests installing renewable energy to power EVs. Further, the study offers policy recommendations aimed at accelerating electric vehicle adoption, promoting sustainable economic growth, and supporting advancements in environmental technologies to effectively reduce CO emissions, while also outlining avenues for future research.
交通运输行业的污染通过在大气中留存热量,在气候变化中扮演着不可或缺的角色。为了减少与交通相关的排放,采用电动汽车为实现无排放道路交通提供了一种经济的解决方案。在此背景下,本研究重新审视了环境库兹涅茨曲线(EKC),并评估了电动汽车、环境相关技术创新和可再生能源对环境的影响。为此,该研究使用系统广义矩估计(GMM)技术分析了38个经济体在2013 - 2023年期间的面板数据。结果表明,采用电动汽车、可再生能源和环境技术均与碳排放的减少显著相关。具体而言,电动汽车采用量每增加一个单位,二氧化碳排放量大约减少0.00000732单位,而可再生能源和环境技术分别使排放量减少0.0005975单位和0.0548603单位。研究结果支持经济增长与碳排放之间呈N形关系,以及环境相关技术创新与碳排放之间呈U形关系。为了减少与交通相关的排放,本研究建议安装可再生能源为电动汽车供电。此外,该研究还提出了政策建议,旨在加速电动汽车的采用、促进可持续经济增长以及支持环境技术进步以有效减少碳排放,同时还概述了未来研究的方向。
