Anthropocene is a term recently used to address the age we live in, since the world is deeply affected by human actions. Climate change is now a matter of facts.
Cities are an emblem of the human impact: they are nowadays hosting more than half of the global population, continuously expanding and representing the biggest source of environmental pollution, but also, possibly, the main key solution.
Theories for a sustainable living started being developed in the previous century and now, more than ever, their application is required.
Eco-cities implement sustainable regulations and technological innovations to provide the urban environment with alternative sources of energy and green living. However, eco-city is a quite common term that is nowadays used to describe a wide variety of phenomena, assimilating completely different implementations, applied in various ways and at contrastive scales. Eco-cities now comprehend projects designed to create entire new cities, built from scratch and isolated from the outside, but also small scale interventions taking place in already existing settlement. Moreover, some of these projects are designed to be models to be exported, without concerns about the contexts.
The aim of the thesis is to investigate and describe all the various applications of the ecological urbanisation, identifying three main models - defined as formulae – and researching their reasons, the issues each one is trying to answer, investigating which one and in which context could represent an effective answer to climate change.
