A paper presented at the 2011 State of Australian Cities Conference reports on the development of VIBAT-Auckland. VIBAT (Visioning and Backcasting for Transport) is a model which enables the carbon impacts of transport policy measures and urban form and planning measures to be assessed in an integrated manner. VIBAT demonstrates the scale of intervention that is likely to be required across a range of policy areas in order to meet carbon emissions targets and has already been developed for a number of overseas cities. This paper explores the potential its application to Auckland in order to make visible the kinds of choices that would need to be made in order to reach the aspirational targets. It also considers how the model enables the more extreme policies to be considered against their potential impacts on the communities that make up the city.
