ABSTRACT
This chapter explains the modelling of potential transport CO2 mitigation and the impacts of available policy interventions. There is a need for cities to lead the way in developing carbon efficient lifestyles, particularly with the recent difficulties in finding a consensus for change at the international level. Cities can certainly push a more radical agenda than seems possible at the international level. But even in the leading cities, such as London, there is an enormous gap between the current strategic 60 per cent emissions reduction targets and business as usual (BAU) trends. Reducing transport emissions is thus a very complex problem; it involves us understanding the sociological factors behind people's rationales for mobilities, and it requires huge investment and social change. The focus of the chapter has been on travel within London, there is a considerable amount of air travel in and out of London as the city is a global hub on the international aviation network.
