A new report by Arup has been seized on by environmentalists, who claim it backs the commercial and practical viability of a 'zero-carbon' Olympic Village.
The study into the proposed zero-carbon Gallions Park development in London's Docklands claims that carbon-free construction is both 'financially viable and technically feasible'.
Now leading members of the London Assembly's Green Party are claiming the Arup findings prove a zero-carbon Olympics is not just a pipe dream.
Ex-archaeologist and former chair of the Green Party Jenny Jones said: '[Gallions Park] is an exciting project which will demonstrate what is possible in London.
'The London Mayor should apply these high environmental standards to all new developments which are under his control, including the Olympic village.
'We want to show what can and should be done with every new development in London.'
London Mayor Ken Livingstone is committed to delivering a number of carbon-free developments as part of his budget agreement with the London Assembly and, earlier this week, revealed his latest targets to reduce carbon emissions by 60 per cent before 2050.
The Arup findings come just days before RIBA president-elect Sunand Prasad is set to deliver his proposals on addressing climate change. The outline policy - details of which are being kept firmly under wraps - will be unveiled at the institute's full council meeting next Thursday (5 October). by Richard Waite
