Abstract: The reducing use of fossil fuels and greenhouse gas emissions is one of the main aims of urban planning. These objectives directly involve urban activities which are responsible for 80% of energy consumption and CO2 emissions and indirectly the transport sector which contributes in the range of 20%-40% in terms of consumption of fossil fuels and emissions of greenhouse gases and particulate matter. In this context, the simulation, the evaluation and the implementation of sustainable mobility policies are a crucial challenge for decision makers and analysts. At this aim, the paper proposes an integrated modelling framework which, following a bottom-up approach, combines a transportation simulation model (demand, supply and supply-demand interaction) with traffic fuel consumption and vehicle emission models. The aim was twofold: 1) specify and implement a modelling framework characterised by a level of detail not usual in literature and able to estimate fuel consumptions and greenhouse gas emissions with respect to any transportation scenario; 2) investigate the effects of different transport policies by applying the system of models. The proposed methodology was implemented to the urban context of Salerno municipality (Southern Italy), within the development of the sustainable energy action plan.
