Metabolic Impact Assessment for urban planning

The functioning of urban systems involves high levels of resource consumption and a complex web of energy, water and material flows. The fundamental aim of this paper is to understand how future urban systems could be designed to be consistently less damaging to the environment. Its main contribution is the proposal of a methodology for evaluating the urban development process from ametabolic perspective, the Metabolic Impact Assessment (MIA). After a brief introduction to evaluation in environmental planning, the paper describes the main influences of MIA, presents a set of principles for a metabolic assessment, and describes in detail the methodology's evaluation procedure.
