London 2012 Olympic games organisers release first green report

London 2012 Olympic games organisers have published the first environment report and have claimed they can deliver the world's first "truly sustainable" Olympic Games.

The report aims to cut the carbon footprint by 100,000 tonnes of carbon emissions in the procurement of materials and venue construction.

In the report's introduction, the organising committee's chairman, Lord Coe, outlined what he felt were among the innovative highlights of the London Games.

"No one had tried to calculate the complete carbon footprint of a Summer Games, and no one had built an 80,000-seat stadium as light in structure and environmental impact as ours," the BBC quoted Coe, as saying.

David Stubbs, the committee's head of sustainability, said the concept of sustainability played a defining role in the whole project.

The main stadium has been constructed using a range of techniques, including recycled material, Stubbs explained.

Jonathon Porritt, a sustainability ambassador for London 2012, praised organising committee's efforts and said progress to date is truly impressive.

"The report speaks volumes about the way in which the very high ambition level for genuinely sustainable Games in 2012 is being translated into action on the ground," he observed.

The report focused on the five main themes of the 2012 Games' environmental strategy- climate change, biodiversity, waste, inclusion and healthy living.

The organising committee plans to publish two reports over the coming two years.
