The challenge of rethinking our approach to housing and economic development to meet the climate change challenge may seem like a big change, but our scale is small compared to the emerging economies in China and India.
A new Arup project in Dongtan, China, visited by John Prescott last month, shows what could be possible. The project team is creating a new city on a carbon-neutral basis.
The Chinese authorities have selected Arup to develop the masterplan for the new 'eco city' of Dontang to shift from an environmentally unsustainable model of development. Dongtan will be a city of three villages. Phase one should be completed by 2010, in time for the World Expo in Shanghai, and will accommodate a population of 50,000, rising to a projected 500,000 by 2040. Dongtan will be self-supporting, generating all its energy needs, including transport, from renewables and will have zero emissions from the tailpipes of vehicles.
The city region will supply the bulk of its energy from wind turbines, bio-fuels and recycling organic material. An Energy Centre will contain the energy supply centre for the entire city of Dongtan. Most of the city's waste will be recycled and organic waste will be composted or used as bio-mass for energy production. There will be no landfill of waste and human sewage will be processed for irrigation and composting.
A combination of traditional and innovative building technologies will reduce energy requirements associated with heating and cooling of buildings by up to 70%. Dongtan will be a city linked by a combination of cycle-paths, pedestrian routes and varied modes of public transport, including buses and water-taxis.
You get the picture. Arup believe this is transferable to the UK. The Thames Gateway will help us to find out.
