Vom öffentlichen Verkehr zur multioptionalen Mobilität? Regulierung digitaler Mobilitätsangebote im Kontext der Klimaschutzziele

By 2030 the German government has set itself the goal of reducing transport related CO2-emissions by 40 %. Scenario studies show that this necessitates a modal shift away from car traffic. As a possible strategy to achieve this, the article discusses the concept of a transition to a “multioptional” mobility system which combines individual and collective modes of transport. In this scenario, public transport will increasingly be combined with new mobility services. The article argues that the sustainability potential of this vision can only be realised if the regulatory framework of transport is fundamentally changed. Within the context of climate protection and digitalisation, municipalities will need to have new regulatory instruments to steer car traffic as well as new mobility services in the direction of sustainability. The article highlights key elements of such a regulatory framework using the examples of car traffic, new mobility services such as car, bike and scooter sharing as well as app-based passenger transport services.
