Imagine a city where private car ownership is optional: metros, buses and trains are just a tap away; bikes, scooters and other micromobility options are docked nearby; and self-driving cars are ready when you need them. For years, the promised deployment of new mobility solutions — such as mobility-as-a-service, micro- and shared mobility and autonomous vehicles — alongside urban policies focused on ”cities of proximity” and climate change mitigation, have held out the prospect of this future. Yet an Arthur D. Little analysis found that car trips still account for around 70% of all miles traveled in urban areas and about 90% in rural areas. Overcoming the barriers to mobility systems is vital. A joint Arthur D. Little/POLIS study, The Future of Mobility 5.0, provides a deep dive into key challenges and highlights promising solutions to overcome them. The solutions necessary for a transformative shift toward urban mobility are within our grasp. Clear game changers to accelerate the transition have already been identified. With comprehensive implementation, appropriate funding and robust governance, the following eight high-impact solutions could potentially double the global share of sustainable mobility from approximately 30% to 60% of passenger miles within the next decade. Climate change mitigation Mitigating climate change’s impact requires a more coordinated policy approach with transport electrification complemented by other levers. This requires a three-step framework: avoid, shift and improve. Avoid: Reduce demand by encouraging drivers to eliminate unnecessary car trips, shortening travel distances and employing behavioral change strategies. Shift: Move to less energy-intensive mobility, away from private cars toward mass public transport, active mobility and new mobility modes. Improve: If the default mode remains a private car, journeys need to be made as sustainable as possible through electrification, better energy efficiency and
