Transport is one of the major global consumers of energy and therefore has an important role in meeting the primary objective of the World Energy Council, sustainable energy for all. Transport is the only energy sector in which the energy itself is mobile during consumption, rather than being delivered for use at a fixed location. For this reason, energy for transport is dominated by petroleum, which is widely available, relatively inexpensive and from which easily transportable liquid fuels of high energy density such as gasoline and diesel are made.
The sustainability of petroleum and other fossil fuels within the timeframe of this study, to 2050, has been put into question by scientists, policymakers and other stakeholders. Sustainability is measured in terms of the 3 A’s criteria of accessibility, availability and acceptability, differentiating between the relative importance of different regions. Sustainability of fuels brings into question the sustainability of the associated vehicle technologies. In this study, existing and potential fuel and vehicle technologies are assessed both qualitatively (by the 3 A’s criteria) and quantitatively (by the contribution to reduced consumption) to determine a roadmap for technologies which can help meet the objective of sustainable energy. Other non-technical measures are also considered. The roadmap of technologies and measures is put into a practical context by considering the policies necessary to ensure that the objectives are met in the most efficient and effective way possible.
