The mobility choices and behaviours of residents and businesses can vary greatly depending on the structure and design of the city. A sprawling city covering large areas with wide highways and no bike lanes discourages cycling and increases dependence on private vehicles, which contribute significantly to resource demand and GHG emissions. Meanwhile, a more compact city with mixed use developments, accessible public transport and extensive and appealing pedestrian and cycle networks enables and encourages walking, cycling and other non-motorised, low-carbon forms of mobility. Combined with urban planning that incentivises higher densities along major public transport routes, transit-oriented development can help to slow the outward expansion of cities into the surrounding countryside.

Compact city planning can help local communities build and create more efficient, safe and viable cities. This concept includes ideas such as the 15-minute city or ‘complete neighbourhoods’, whereby all of the basic needs and services of a resident can be accessed within 15 minutes by walking, cycling or public transport. This concept has also attracted attention as a way to reduce inequality by ensuring that all neighbourhoods have access to affordable mobility options.

Local governments can support the development of compact and low-carbon cities by integrating such concepts into the city’s urban plans, and ensuring that all residents are easily able to conduct their day-to-day lives using non-motorised or public transport. Cities can also ensure that necessary and facilitating infrastructure is provided, such as cycle lanes, pedestrianised areas and public transport options, to enable the shift away from dependency on personal vehicles.
