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.
