A growing number of studies empirically investigate the nexus between CO2 emissions and technological progress in the existing literature. However, these studies largely ignore sectoral-level differences. We argue that as the contribution of different sectors to carbon emissions are not equal, the environmental impact of technological progress might vary across sectors. The main purpose of this paper is to fill this research gap for the transport sector. To this end, we specifically focus on the EU15 countries over the period between 1977 and 2015. In order to empirically analyze this link, we use the Mean Group, Common Correlated Effects Mean Group, and the Augmented Mean Group estimators. Unlike the earlier country-level empirical studies, our findings reveal that environmental technologies have a statistically insignificant positive effect on CO2 emissions from the transport sector. Moreover, while economic growth and energy consumption lead to more pollution, the effect of urbanization on emissions is not statistically significant. It is recommended that the policymakers of EU15 countries should pay special attention to the transport sector for becoming a carbon-neutral economy by 2050.

环境技术是否有助于减少交通部门的二氧化碳排放?来自欧盟 15 国的证据

在现有文献中,越来越多的研究对二氧化碳排放与技术进步之间的关系进行了实证研究。然而,这些研究在很大程度上忽略了部门层面的差异。我们认为,由于不同部门对碳排放的贡献不相等,技术进步对环境的影响可能因部门而异。本文的主要目的是填补交通部门的这一研究空白。为此,我们特别关注 1977 年至 2015 年期间的 EU15 国家。为了实证分析这种联系,我们使用了平均组、共同相关效应平均组和增强平均组估计量。与早期的国家级实证研究不同,我们的研究结果表明,环境技术对交通运输部门的二氧化碳排放量具有统计学意义的积极影响。此外,虽然经济增长和能源消耗导致更多污染,但城市化对排放的影响在统计上并不显着。建议欧盟 15 国的政策制定者应特别关注交通运输部门,以便到 2050 年成为碳中和经济体。
