British design firm Arup is set to announce that the Chinese government wants them to take their "eco-friendly city" model to up to four more major Chinese cities, the UK Guardian reports.
Up to four more eco-cities will be built, though exact locations have not yet been revealed. [...] The eco-cities are intended to be self-sufficient in energy, water and most food products, with the aim of zero emissions of greenhouse gases in transport systems.
Arup's work with the Shanghai expansion, Dongtan, is underway. The first phase, a 630-hectare development intended to house a 50,000-person community, is set to be completed by 2010.
