Engineering measures in the London 2012 construction project have won praise from sustainability experts.
A report by charities Bioregional and WWF found construction methods had gone some way to delivering on a promise to make the Games a ‘One Planet Olympics’.
It said: “The use of temporary structures, lightweight venues, sustainable materials and legacy-proof design shows leadership with strong potential to be emulated at future sporting mega-events.”
Meanwhile, a failure to meet renewable energy targets or use relationships with sponsors to fully embed sustainable practices were highlighted as down sides of the London Games.
The report added: “Our assessment shows that in many areas the promise of moving towards a One Planet Olympics is on track, but that in some significant areas failures have occurred.”
