About this report
A clean, efficient and effective city transport system is critical to economic growth and to the health and welfare of inhabitants and workers. Yet transport users in most cities experience slow journey times, crowded transport systems and the direct and indirect impacts of inefficient and polluting vehicles.The International Energy Agency has identified three critical factors to guide policy makers in improving city transport systems to increase efficiency while simultaneously mitigating the negative climate, noise, air pollution, congestion and economic impacts of rising urban transport volumes.
