PARTNERSHIPS FOR SUSTAINABLE MOBILITY: The Polot Region of Basel

摘要

The rising use of motor vehicles is providing increasing parts of the global population with convenient and comfortable mobility options for trips related to commuting, shopping, leisure activities, and other pursuits. However, the world's vehicle fleet poses major challenges for local air quality in urban areas as well as for global climate protection: Motor vehicles contribute up to an estimated 64 percent of sulfur dioxides, 69 percent of suspended particles, 97 percent of carbon monoxide, 95 percent of hydrocarbons, and 92 percent of nitrous oxides found in some urban areas—mainly in developing countries. At the same time, motor vehicles are responsible for roughly 20 percent of carbon dioxide (CO_2) emissions in developed countries such as the United States.
