This Thematic Research Summary on the environmental aspects of transport and
sustainable mobility aims to provide the reader with a synthesis of results of completed
European research projects related to that theme. It consists of two main parts. The first
part includes a brief overview of the scope of the theme and summarises the main policy
developments at EU level relevant to the theme. The second part contains a synthesis of
the main findings and policy implications from research projects and identifies the
implications for further research. The research projects for which the synthesis is provided
are European (EU-funded and national) projects that are completed and with results
publicly available. The EU projects have been funded by the Fourth, Fifth and the Sixth
Framework Programmes. Projects that had been reviewed in the related paper produced
within the predecessor project EXTR@Web [2] are only briefly summarised in the background
section for each sub-theme.
