Abstract

Deterioration of urban air quality caused primarily by the large amounts of urban vehicle traffic, has led to increasing scrutiny of vehicle technologies and their exhaust emissions. Legislation has been put in place in recent years to force a reduction in the exhaust emissions of new vehicles running on conventional petrol and diesel fuels. Such legislation should have a significant impact on air quality, but is it enough?

This question has lead many urban local authorities and urban fleet operators to consider what benefits might accrue from the use of alternative vehicle fuels such as natural gas or electricity. In particular there is growing activity in the use of alternative vehicle fuels in urban buses - we see for example the electric buses in Oxford and the use of liquid petroleum gas in buses in Bath.

This paper is based on the work of two projects carried out by ETSU for the UK government.

The first is a life-cycle study into the costs, energy use and emissions associated with a range of alternative vehicle fuels and the second is an energy and emissions assessment of alternative fuels currently in use with UK vehicle fleets. Both these projects have produced a wealth of data concerning the energy use, emissions and costs associated with alternative vehicle fuels in the UK. Combining this information the paper will draw a picture of the different alternative fuels that are in use today in public transport, discussing the costs of using these fuels and the benefits that can be achieved in terms of improved air quality.
