Introduction Provision of environmentally sustainable (or green) private transport throughout the world faces two main challenges. The first is ur and even regional air pollution, particularly in the rapidly growing cit the industrializing world. The second is global climate change, caused mainly by rising concentrations of greenhouse gases (GHGs) in the atmosphere. These two barriers to green car mobility differ in several important ways. First, road traffic air pollution problems are more locali because of the short atmospheric lifetimes of most vehicle pollutants andThus regional solutions are often not only possible, but also essential- Australian cities, for example, can (and must) solve their air pollution problems themselves- Matters are very different for global climate chang Except possibly for geo-engineering measures such as placing large quantities of sulphate aerosols in the lower stratosphere or erecting huge reflecting mirrors in space，one country cannot solve this problem alone. Climate change is a global problem. Nevertheless, it is possible for some countries to ‘freeload’ if the majority of nations that are important GHG emitter. Second，there is agreement that air pollution, especially in urbaareas ，is potentially a serious health hazard ， and that road transport can contribute greatly to urban pollutant level For these reasons,• govern in many countries are already taking effective action on air pollution. until recently, climate change was not recognized as a major problem by some key policy...
