Hong Kong leads the world for sustainable transport according to the 2017 Sustainable Cities Mobility Index from Arcadis, the leading global Design & Consultancy for natural and built assets. European cities dominate the top of the overall Index, occupying seven of the leading ten spots.

Boosted by its innovative and well-connected metro network and a high share of trips taken by public transport, Hong Kong manages to achieve many of the aims of an effective urban transport system - enabling comprehensive mobility, creating economic opportunity and enriching the lives of citizens, business and tourists alike.

Cities benefiting from 'money, mass or maturity', namely high wealth, significant global cities, do not necessarily lead the ranking in sustainable urban mobility. Although these factors can help, we do see wealthy, large and/or older cities not automatically punching their ticket to sustainable urban mobility.

Although there is no magic recipe for the creation of successful and sustainable urban mobility, higher ranking cities have a better balance across the three pillars of sustainability - social (People), environmental (Planet) and economic (Profit). The Index was compiled for Arcadis by the Centre for Economic and Business Research (Cebr) and explores mobility through these three pillars of sustainability to develop an indicative ranking of 100 of the world's cities.

Zurich, Paris and Prague are the highest placed European cities, ranking second, third and fourth respectively, with strong scores in the Planet and Profit sub-indices - due to established infrastructure, efficient metro systems and commitment to green technology.
