Changes in urban mobility have direct impacts on the quality of the built and natural environment. These impacts concern primarily air quality and emissions as well as noise levels, vibration and visual intrusion - and in nearly every case they are adverse and getting worse. The urban poor in developing countries are especially vulnerable to these adverse environmental impacts. Many initiatives have been implemented to reduce negative environmental impacts but continuing growth in transport activity is offsetting the gains achieved. Overall, insufficient progress has been made towards achieving environmental sustainability in the urban transport sector.
