Achieving sustainability in urban transport in developing and transition countries | Umweltbundesamt

Transport accounted for 23% of global ⁠CO2⁠ emissions in 2007. It is expected that both the overall emissions and the demand for energy in transport will continue to rise in the next decades unless appropriate policy measures are introduced. While fossil fuels will become scarce over the next decades, mobility is one of the basic needs of people today and there is a reinforcing correlation between economic and social development on the one hand and mobility and accessibility on the other. There is a pressing need to improve the sustainability of transport in order to reduce its impact on climate change, better support economic growth, improve energy security and achieve the Millennium Development Goals (MDGs). Unsustainable transport can cause air pollution, noise, accidents and other negative sideeffects harming people and the environment. These effects are especially relevant in urban areas. Today about 50% of the world’s population of 6.9 billion people lives in cities.
