“We need to exploit the opportunities that electric mobility offers” In order to achieve our climate targets, we must take a new approach to road transport in the future. Therefore, it is essential for governments to set a clear course at an early stage. In this interview, Dr. Uwe Lahl, Director-General at the Baden-Württemberg Ministry of Transport, explains how we can redesign and restructure our mobility systems.
ATZ _ Dr. Uwe Lahl, how can public and
i ndividual transport be better coordinated in the future to enable traffic to flow more smoothly and to reduce emissions of CO2, NOx and particulate matter? LAHL _ Public
transport can always interact more successfully with individual transport, which includes walking, cycling, car driving and bike and car

sharing, when users are able to make continuous journeys on different modes of transport. We can achieve the greatest benefits for the environment and the climate if ecomobility solutions – in other words, public transport, walking and cycling – are given priority. The transition between the different means of transport should be made easier by
establishing mobility hubs, mobility stations and park-and-ride facilities and by modernizing existing bus stops, for example. This applies to both urban and rural areas. To ensure a better flow of traffic in large cities, car drivers need to be given information via a satnav system or an app not only about congestion but also about available parking spaces and
public transport services during their journeys. The Ministry of Transport has created MobiData BW, which lays the foundations for the information to be provided. The car manufacturers and their suppliers are then responsible for implementing the information services. To what extent can a “green wave” reduce the amount of pollution produced?
It would be a mistake to think that making the traffic flow more smoothly will significantly lower pollution levels. It is true that less stopping and starting brings benefits, but only to a limited extent. We once calculated the hypothetical impact of the “perfect green wave” in Stuttgart. Depending on the type of pollution, the reduction in emissions amounts to between 2 and 5 %.
ular option at the moment. This is because they are much more energy-efficient than fuel cell vehicles or cars that run on synthetic fuels, for example. We need to continue focusing on producing energy from renewable sources in order to achieve our climate targets. Battery electric vehicles are currently market-ready and can therefore make a better contribution to achieving technology neutrality, lowering emission levels and reducing noise. However, we must not lose sight of the other technologies available.
“The EU and Germany became involved in electric mobility far too late”
The EU is focusing its efforts on making mobility carbon-neutral, which almost exclusively involves electric vehicles. Is this the right route to take? Or are we making electric mobility our top priority when this is not technical
