One of the greatest challenges we face today lies in sustainable and innovative mobility. People require a seemingly endless network of vehicles and transportation systems. Sustainable urban mobility requires a mind shift: where transport in private cars and trucking give way to different modes of public transport. Like bicycle and pedestrian lanes, electric vehicles, car sharing. Cities all over the world are rising to meet the challenge. The above fact has motivated the current study, having as main goal to provide a literature review of the topic, investigating the current situation in eight megacities around the world, those of Istanbul, Tokyo, London, Sao Paulo, New Delhi, Cairo, Shanghai and Chongqing. Comparative analysis is adopted as a methodological tool, taking into account a wide range of aspects within sustainable mobility and using Deloitte’s city mobility index as metric. The results show that each one of the megacities differs in terms of the adoption of sustainable development measures for their urban mobility. The level of integration of these measures varies due to several factors, such as the economic and technological development of each one of them as well as their social background. Although, all eight cities “realize” the importance of transition and adopt policies in that particular direction, they still have a long way to go so as to guarantee the maximum benefits.
