Energy use in the global transport sector is poised to double by 2050 despite ongoing improvements in vehicle technology and fuel economy, and urban transport accounts for 40 percent of total transport-related energy consumption. Under a business-as-usual scenario, the total number of urban passenger-kilometers traveled could triple in the period 2010–2050.

Cities must find ways to meet mobility challenges while also reducing overall greenhouse gas emissions from transport. Cities offer an immense opportunity to scale up sustainable, low-carbon transport solutions to contribute to climate change mitigation, to achieve positive health outcomes through non-motorized transport, and to create more-compact developments that increase residents’ access in addition to improving mobility.

“Many cities already have the necessary ingredients to reduce climate change impacts, and the current need is to prioritize these existing factors for success.”
