Larger vehicles are better on long distances in order to increase volumes trans- ported, but there is no real benefit of using them in city distribution, according to CEOTGM and CEOGBF. Instead, the vehicles are both shorter and smaller than the maximum allowed in order to make deliveries on time and to gain acces- sibility in the streets and loading docks. CEOGBF points out that normally economy and the environmental impacts go hand-in-hand, but not always. He exemplifies this with the investment cost for a gas- and petrol-fuelled lorry being higher than an ordinary lorry.
