The transportation industry plays a vital role in the achievement of the United Nations’ 17 Sustainable Development Goals (SDGs). These goals target economic, social, and environmental dimensions of sustainable development, with the transportation sector having a significant impact on each of these areas. This essay will discuss the relationship between the transportation industry and SDGs, focusing on the challenges, opportunities, and strategies for aligning transportation policies and practices with sustainability objectives.
The transportation sector is a key driver of economic growth, contributing to SDG 8: “Promote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all” [1]. The industry facilitates the movement of goods and people, fostering trade, enhancing productivity, and promoting regional integration. According to the World Bank, investments in transportation infrastructure can lead to increased economic growth and job creation [2].
However, the transportation sector also presents significant sustainability challenges, such as environmental degradation and social inequalities. For instance, the sector accounts for approximately 23% of global energy-related CO2 emissions, contributing to climate change and air pollution [3]. Additionally, transportation systems often prioritize private vehicles, leading to urban sprawl, traffic congestion, and limited accessibility for low-income populations. These issues highlight the need for a sustainable transportation paradigm that supports SDGs.
An essential principle for sustainable transportation is the “avoid-shift-improve” (ASI) framework [4]. The ASI framework promotes policies and practices that encourage reducing the need for motorized transport (avoid), shifting towards more sustainable modes of transportation (shift), and improving the energy efficiency and environmental performance of vehicles (improve). By implementing the ASI principles, the transportation sector can contribute to various SDGs, such as SDG 7 (affordable and clean energy), SDG 11 (sustainable cities and communities), and SDG 13 (climate action).
To illustrate the potential of sustainable transportation strategies, the following examples showcase interventions that support SDGs.
First, promoting public transport and non-motorized modes of transportation, such as cycling and walking, can contribute to SDG 11 and SDG 13. An analysis of 483 cities worldwide found that cities with higher public transport usage had lower CO2 emissions and better air quality [5]. Moreover, a study in Denmark showed that investments in cycling infrastructure yield positive returns in terms of health benefits, reduced congestion, and decreased CO2 emissions [6].
Second, the development of electric vehicles (EVs) and the expansion of charging infrastructure can support SDG 7 and SDG 12 (responsible consumption and production). A comprehensive review of the environmental impacts of EVs concluded that they generally have lower life-cycle emissions than conventional vehicles, especially when powered by renewable energy sources [7]. Furthermore, a study in the European Union found that EVs could reduce oil dependency, lower greenhouse gas emissions, and create employment opportunities along the supply chain [8].
Third, implementing land-use planning and urban design strategies that encourage compact, mixed-use, and transit-oriented development can support SDG 11 and SDG 10 (reduced inequalities). A review of 46 studies on the relationship between urban form and travel behavior found consistent evidence that compact and diverse urban environments are associated with reduced car use, increased walking and cycling, and improved public transport accessibility [9]. These findings suggest that sustainable urban planning can promote social equity and environmental quality.
In conclusion, the transportation industry has a crucial role in achieving Sustainable Development Goals. By adopting sustainable practices, prioritizing public health, and developing innovative solutions, the sector can contribute significantly to global efforts toward a more sustainable future. As the world continues to urbanize and the demand for mobility grows, it is imperative that policymakers, industry stakeholders, and citizens work together to create a transportation system that supports the economic, social, and environmental dimensions of sustainable development.
