The goal of this paper is to demonstrate how system dynamics modelling can be used in e-government policy and systems as an aid to spport territorial ananlysis, planning and governance, sustainable performance in urban areas and the assessment of policy outcomes. Topics such as renewable energy, efficiency, the design and exploitation of urban energy, water and waste management infrastructure and the alignment of different stakeholders provide relevant fields of study for the analysis of this paper. Specifically, we reflect upon the way in which a preliminary dynamic performance management model of an exemplary case study can be used to foster a common shared view among different policy makers as a way to highlight new ways to enable sustainable development in urban areas.
