| dc.description.abstract | Previous research has showed that the era of cheap fossil fuels is over. Also, 23% of the
worldwide emission of CO2 is produced by road transport. These problems demand a change
in the propulsion of vehicles. Because the diffusion of clean-fuel vehicles is not happening at
this moment, something has to change Rogers’ diffusion of innovation theory is used to state
that a critical mass of vehicles is needed to stimulate the diffusion of these vehicles. Due to
public procurement Dutch local authorities (DLA’s) can help stimulating this diffusion.
Unfortunately these DLA’s are not purchasing clean-fuel vehicles yet. To gain insight in what
is hampering the diffusion of these vehicles by DLA’s, a discrete choice experiment was
created about the preferences by these DLA’s. Six vehicle attribute were used to describe
each vehicle. The results showed that the initial purchase price and the amount of local
emission were experienced as the most important attributes by DLA’s, where initial purchase
price has a negative influence and local emission a positive influence in the choice for a new
vehicle. Next, fuel price, range and availability of the fuel were found evenly important. Fuel
price had a negative influence and both range and availability of fuel had a positive influence
on the choice for a new vehicle. Finally time to refuel/recharge was found least important and
also negatively influencing the choice. | |
