摘要

The world's carmakers have been actively engaged in finding alternative fuels for motor vehicles for some years and one already used in the US and continental Europe, if not yet significantly in the UK, is liquefied petroleum gas. Although motor vehicles emit 80 per cent fewer pollutants than they did up to 15 years ago, there are millions more cars on the roads today that are responsible for 80 per cent of carbon monoxide pollution and at least 40 per cent of ozone-forming pollutants in urban areas.
