Cities and Pollution
For years cities have been painted as environmental villains. Just as cities dominate global trading systems so they lie at the heart of global systems of resource consumption and pollution.
Yet resource consumption and pollution is created not by cities but people. London may produce approximately 60 million tonnes of CO2 a year but would these environmental impacts be any less if London's 7 million inhabitants were living in eco-villages spread across the south of England? If this were possible, we might imagine more food growing, local power generation, even reed beds for sewage treatment.
Cities are central to cultural and economic life. The dense, walkable city may be the most sustainable form of human settlement for the majority of people. For all their benefits, new settlements and eco-villages will only ever serve a fraction of the population. However urban sustainability is a complex issue as Robert and Brenda Vale have said: "Green Architecture must encompass a sustainable form of urban development. The city is far more than a collection of buildings, rather it can be seen as a series of interacting systems - systems for living, working and playing - crystallised into built forms. It is by looking at these systems that we can find the face of the city of the future". These systems are not neatly confined to the neighbourhood or even the whole city but operate on a regional, national and global level.
