Abstract
Although the transportation sector is a crucial component of economic growth, it also substantially contributes to environmental degradation. Thus, in alignment with the United Nations Sustainable Development Goals (SDGs), the decarbonization of the transportation sector is pivotal for achieving SDG 11. Therefore, this study explores the underlying role of biofuel consumption (BC), green technology innovation (GTI), and environmental policy stringency (EPS) in abating transport sector emissions for eleven emerging economies spanning from 2005 to 2022. This study examines the individual and moderation effects using the cross-sectional augmented autoregressive distributed lag (CS-ARDL) and augmented mean group (AMG) estimators while addressing the heterogeneity and unobserved endogeneity issues. The empirical findings posit that while biofuel has a positive impact, EPS has a modest but negative impact on transportation emissions. Conversely, GTI significantly abates transportation emissions in emerging countries. Besides, the moderation effect of EPS with BC and GTI significantly abates transportation emissions in the long run. Thus, this study suggests implementing coherent policies that include tax benefits, biofuel mandates to produce advanced biofuel products, and coordinated efforts to strengthen institutional and regulatory frameworks to decarbonize the transportation sector and achieve sustainable goals.
期刊介绍：
In our first issue, published in 1972, we explained that this Journal is intended to promote the free and vigorous exchange of ideas and experience among the worldwide community actively concerned with transportation policy, planning and practice. That continues to be our mission, with a clear focus on topics concerned with research and practice in transportation policy and planning, around the world.
These four words, policy and planning, research and practice are our key words. While we have a particular focus on transportation policy analysis and travel behaviour in the context of ground transportation, we willingly consider all good quality papers that are highly relevant to transportation policy, planning and practice with a clear focus on innovation, on extending the international pool of knowledge and understanding. Our interest is not only with transportation policies - and systems and services – but also with their social, economic and environmental impacts, However, papers about the application of established procedures to, or the development of plans or policies for, specific locations are unlikely to prove acceptable unless they report experience which will be of real benefit those working elsewhere. Papers concerned with the engineering, safety and operational management of transportation systems are outside our scope.
