As it enters its final few days, officials in London say the 2012 Olympics are on track to be the ‘greenest Games’ in history.
The original bid to host the 17-day event included plans to holding the most environmentally friendly tournament possible.
Organisers point to the regeneration of what was wasteland leftover from London’s industrial past, which has been transformed into the Olympic park.
David Stubbs, Head of Sustainability for the Games’ organisers LOCOG said the area had been polluted and then neglected for generations.
“This was a derelict wasteland with contaminated land, rivers full of rubbish, broken down buildings.”
The Olympic cauldron uses just 15 percent of the gas used at the Beijing Games, organisers claim.
Following the games, the site will become the Queen Elizabeth Olympic Park with plans to convert even more of the land into precious London parkland.
But environmental campaigners wanted London 2012 to generate enough renewable energy to replace the amount consumed. The WWF says the games will neither be zero carbon nor zero waste.
They hope Rio, a city that has become a symbol of sustainability, will do more for the green cause in 2016 when it hosts the next Olympic Games.
