Emissioni zero e sostenibilità ambientale: il Sustainable Energy Action Plan (SEAP) come strumento operativo per la pianificazione di interventi eco-razionali su di un sistema dei trasporti

A city without oil is a general goal aimed at gradually reducing the use of fossil fuels and greenhouse gas emissions in the different urban funcitions. These objectives are widely acknowledged both at the world (Kyoto and Cancun) and European (White paper and 20/20/20 strategy) levels. The impact of the transport sector is in the range of 30%-50% in terms of consumption of fossil fuels and emissions of greenhouse gases and particulate matter. In this context, policies aimed at reducing these effects are very important. Furthermore, the recent economic crisis has forced the public administrations to cut investments for urban mobility projects, forcing planners to consider explicitly the problem of a rational use of economic resources. The paper discusses the concept of eco-rationality applied to the Naples Sustainable Energy Action Plan (SEAP) by comparing the effects of consolidated "sustainable" transport policies simulated by a set of mathematical models extended to capture energy and pollutant emissions and implemented in a Decision Support System.
