The Tianjin Eco-city is set to be the largest in the world and when completed in the early part of the next decade will be the home to some 350,000 people.

The new city, which is 40 kilometers from the center of Tianjin and is a joint venture between the Chinese and Singaporean governments, could be one of around 100 eco-cities eventually established around China.

Chris Twinn, senior sustainability consultant and a director of UK engineering giant Arup, based in Shanghai, says

Tianjin looks set to achieve a 10 to 15 percent energy saving on a conventional city.    (a pathetically small improvement on ObeCities)
