Speaking at the event, Jonathan Murray, Powershift manager, said that businesses had a major part to play in driving environmental issues forward. He said: 'When we go to see fleets they are asking more detailed questions now, which shows the message about alternative fuels is getting through.
'Instead of wanting to know what liquefied petroleum gas is, fleets are asking about installation, costs and residual values. We have to focus on fleets at the moment, particularly depot-based ones, both in the public and private sectors, because they are the people who can make most use of alternative fuels and an infrastructure could be created more easily for them. But we are also targeting vehicle manufacturers and fuel suppliers to make sure they are helping provide for fleets and private buyers.'
