As already described, taxis are the “mile-eater” in city traffic. Therefore this relative small group of users is responsible for an unproporsional amount of energy consumption and emissions. Yet, this fact also offers the opportunity to achieve an enormous effect in reducing the fuel consumption as well as the negative environmental impacts with little effort.
There are numerous approaches which can contribute to higher efficiency and thereby to the lower fuel consumption of the vehicles. For example the application of just one of the following aspects already enables a substantial effect.
- Weight reduction (less weight of 50 kg): up to 3 % less fuel consumption
- Driving with closed windows: up to 10 % less fuel consumption
- Foresightful driving style: up to 20 % less fuel consumption
- Lowering the air resistance (e.g. container for ski / roof baggage): up to 22 % less fuel consumption
- Deactivation of the air conditioner: 17 to 30 % less fuel consumption
Of course, some of these issues are less useful than others for taxi drivers. As the taxi drivers spend most of the time in the vehicle and have to keep the concentration up on the road, comfort services (such as air conditioning) are usually indispensable. Since the available space should be kept free for passengers of the taxis, unnecessary additional loads are most likely prevented by the drivers, wherefore this topic is also rather marginal.
In contrast the driving style is an important effect for taxis as well as for every single driver on the road. This has already been recognized by the taxi companies, for which reason special trainings for an improved energy efficiency driving are offered to their employees. In most of the cases the success of these actions doesn’t last very long or isn’t measurable at all. It’s hard for everyone to lay off habits. For this reason a long lasting increase of the energy efficiency of the taxis is almost impossible by such means. By an appropriate incentive for the taxi drivers however more sustainable results could be achieve.
