Reflections on Transport Development is being given in this short paper. Specifically : How it was portrayed in the forum on Development and Mitigation and the ways in which it is argued differently in the ‘sustainable transport’ field. The focus is on passenger transport in urban areas. The matter of space, particularly urban space, was largely absent from the forum discourse, (except where highlighted by the provocateurs) and yet it is a central matter in the sustainable transport discourse, which argues for a multi faceted view of transport emissions. From a sustainable transport perspective, distance travelled is a key variable.
