Green charity WWF is helping the London 2012 Olympic bid team to design the most environmentally friendly Games in history.
Last week's bid proposals outlined an event that would run with sustainable transport, zero waste, low carbon emissions, and conservation of natural habitats and wildlife.
The commitment makes London the only Olympics candidate city to adopt the sustainable-living principles devised by WWF and environmental organisation Bioregional.
Both organisations joined the bid team's environmental steering group, which comprised 10 charities advising on various aspects of the bid, this spring. Paul King, campaign director of WWF's One Planet Living programme, said: "We encouraged the bid team to go further than perhaps they thought they would be able to."
WWF and Bioregional will spend the next three months shaping crucial bid details to present to the International Olympic Committee's evaluation team in February. "We plan to present a business plan that other NGOs will be happy to endorse," said King.
