Sustainable transportation strategies for decoupling road vehicle transport and carbon dioxide emissions

Abstract

Purpose

The purpose of this paper is to identify research priorities to guide transportation stakeholders in their practice, education, and research.

Design/methodology/approach

A literature review of published, conference proceedings, agency reports, books, and web site documents was conducted, aiming at the identification of the diverging strategies and practices undertaken by transportation stakeholders in order to be able to generate initial meaningful insights about a sustainable transportation system.

Findings

Sustainable transportation systems are in certain way a new paradigm where a business-as-usual approach is not possible. Vehicle makers produce more energy efficient vehicles. Nevertheless, fossil fuel is still the predominant source of energy. Regarding the level of carbon dioxide (CO₂) emissions, non-motorized transport modes are preferable over motorized transport modes, and public transportation modes preferable to private transportation modes. It is also import to include environmental consideration along the design, construction, maintenance, and operation of the transportation infrastructure. While vehicles powered by alternate fuel such as biofuel, electricity, and/or fuel cell are becoming more popular, shifting to more sustainable transport modes would also require changes on commuter behaviors and individual preferences.

Practical implications

The paper discusses the efforts that are underway for decoupling transport and CO₂ emissions, being useful for transportation stakeholders to implement or improve the effectiveness of their potential or current sustainability transport initiatives through the identification of strategies, opportunities, and barriers.

Originality/value

Although there is plenty of good information about sustainability and transportation modes in literature, most of the articles analyzed focus on specific factors of the whole transportation system. The originality/value of this paper is found in the holistic perspective, here presented, of the state of the art issues that a sustainable transport system would encompass.
