Eco City

ON AN island at the mouth of China's Yangzi River, plans are afoot to build the city of the future. The first residents will move in within five years. The city will be self-sufficient in energy and water and will generate almost no carbon emissions. Petrol and diesel vehicles will be banned in favour of solar-powered boats and fuel-cell-driven buses. The developers of this “eco-city”, called Dongtan, hope that it will come to be seen as a model for the rest of the world: London's mayor, for one, is already inspired by it.
