A 2024 study called The ABC of Mobility shows that 51.4% of commuters across 794 cities in 61 countries travel by car. Although the negative impacts of congestion and combustion engine cars are undisputed — air and noise pollution, GHG emissions and inefficient use of public space, to name a few — the transition to more sustainable options is slow.
The study finds considerable differences between cities, correlating with income and region:
- In cities with twice the average income, 37% more trips are made by car.
- In cities in Asia, a significant portion of trips are by public transport. In cities in the US, Canada, Australia and New Zealand, trips are mainly by car, regardless of city size. Within Europe, there are notable differences in the share of different modes of transport, from cities with predominantly active mobility (like cycling in Utrecht) to cities where public transport plays a crucial role (the subway in Paris or London), to cities where more than two out of three trips are made by car (such as Rome and Manchester).
