Abstract: European Union countries’ current energy policies for the transport sector promote, amongst other initiatives; urban mobility plans, the renewal of fleets of cars and industrial vehicles and the introduction of biofuel. From the point of view of eco-efficiency and Life Cycle Assessment (LCA), energy policies must go further. The objective of this paper is to analyse the current transport model and the policies on energy efficiency being promoted in the EU from a LCA point of view. Special attention has been paid to private vehicles, in assessing the environmental impact of the various stages of manufacture, their use and disposal, and the consequences of plans to renew fleets. How old should a vehicle ideally be so that when it is changed, the embodied energy in the materials of the vehicle is less than the gain in energy efficiency due to changing the model for example? In addition the paper analyses the different means of transport in the energy consumption–time ratio from a LCA viewpoint. The fact that reducing transport times leads to greater energy consumption gives rise to the question: how long does nature take to repair the environmental damage caused?
