The mobility systems of the participating cities rely largely on fossil fuel based motorized traffic. Reliance on private cars increasingly causes congestion. The use of fossil fuels leads to air pollution and substantial CO2 emissions. One participating city noted that 70% of its CO2 emissions derive from mobility. Changing this system is challenging, many cities feared that measures reducing car-use would be met with strong political backlash. A complicating factor is the complexity of the mobility system, it is often difficult to predict the impact and monitor the results of measures. However, changing a city’s mobility system is worth it. When approached in an integrated manner, a sustainable shift in mobility leads to better air quality, good public spaces, and improved equality. In some cases, a shift in mobility functions as a lever for other sustainable transitions. Due to the sizeable spatial and financial claim of mobility this integrated way of working is not only desirable, but necessary. Below are three strategies employed by the Multiply cities to make mobility more sustainable, click on each strategy to reveal specific solutions.


Congestion, CO2 emissions and air pollution are reduced by shifting the modal split, from car-use ]towards walking, biking, and public transport. This shift requires not only alternative options, but also for these options to be appealing.

Reduce car movements

In many cities unnecessary or excessive car movements came forward as an issue. Peak traffic and crowded roads lead to congestion which in turn leads to higher CO2 emissions and air pollution.


Electric mobility reduces emissions and pollution. E-mobility demands more electricity and requires infrastructure. It cannot be addressed separately from the planning of local energy systems.
