Following the annual G20 meeting in Mexico, where for the first time urban public transport was specifically mentioned, the International Association of Public Transport (UITP) reiterates its stance that a commitment to, and investment in, public transport is crucial to achieving sustainable development. 

With the world’s urban population set to rise to 4.5 billion in 2025 from 3.2 billion in 2005, efficient urban mobility and adequate urban public transport infrastructure are critical to helping achieving sustainable, green growth.  

The number of trips made in urban areas every day will increase by 50% between 2005 and 2025, reflecting not only the growth in urban population but also the increase in the number of trips made by each citizen, mainly in developing economies. 

If current trends prevail, the most notable change in urban transport patterns between 2005 and 2025 will be the shift from walking and cycling to private motorised vehicles, driven by fast economic development notably in Asian countries, with the associated economic and environmental costs. Urban congestion will gridlock cities whilst energy consumption and greenhouse gases will increase by 30%, endangering not only the climate but bringing green growth to a halt.  

Cities are the powerhouses of the economy. They concentrate 80% of the world economic output. Efficient mobility in cities creates economic opportunities and social integration, enables trade, and facilitates access to markets and services. Fast urban population growth - associated with urban sprawl - generates more and longer daily trips in cities, exerting significant pressure on transport infrastructure and natural resources, particularly in emerging economies.
