There is no progress without mobility. Mobility is a key factor for both economic growth and safe, social and climate-friendly development. Not only is well-developed transport infrastructure essential for exchanging goods; it also connects people and gives them access to jobs and basic services such as education and healthcare. Transport infrastructure also forms the backbone of other supply services, such electricity and water pipes, which generally run along main roads. In addition to the expansion of rural roads and long-distance transport, there is particular need for action in cities. The transport sector is the fastest-growing emitter of greenhouse gases, nowadays urban transport in OECD cities alone accounts already for one quarter of greenhouse gas emissions. In view of the rapidly growing vehicle ownership rates in developing and emerging countries, this share will increase significantly globally. The critical traffic condition in cities does not just have a negative impact on the environment; it also puts people’s health at risk, reduces the overall quality of life and is detrimental to the economy. In view of this situation, KfW is promoting projects worldwide, aiming to improve urban transport, expand rural roads and support the economy on account of better long-distance and freight transport.
