An expected 1.9 million tonnes of greenhouse gases are expected to have been produced over the seven years of the project - from London winning the bid to the Games taking place.

 

This is after sustainability and reduction measures, according to London 2012 who have billed the Olympics as the most sustainable Games.
 

It means that London 2012's carbon footprint amounts to 0.05 per cent of the UK's total emissions.
 

The figures are included in London 2012's Sustainability Plan - Towards a One Planet 2012 - the first time that a summer Games has produced a study projecting its potential carbon footprint.

 

It is seen as a way to look at the possible impact.
 

Sustainability climate change, waste, biodiversity, inclusion and healthy living are the main issues focused on.
 

Shaun McCarthy, the chairman of the Commission for a Sustainable London 2012, the body set up to independently assure London's 2012 pledge to host the most sustainable Games to date and its legacy, described the study as an "honest appraisal of progress to date".
 

He said: "It is a significant improvement on previous documents in that it provides a rich picture of the huge range of initiatives under way to support the sustainability agenda.
 

"We accept that LOCOG are breaking new ground in the event management sector and that it is impossible to set comparative targets.

 

"We believe that LOCOG are in a position to present greater focus to some of the absolute targets related to the five key themes.
 

"Specific, outcome-based targets for biodiversity and healthy living would be welcome. More prominence should be given to targets already in place, such as emissions limits for vehicles.
 

"We welcome LOCOG's new commitment to waste diverted from landfill for temporary materials."

 

Simon Lewis from WWF, the global conservation organisation which worked with London 2012 on the bid for the Olympic Games and Paralympic Games said: "WWF recognises the strides that London 2012 is making towards the goal of a One Planet 2012 - and the first sustainable Olympic and Paralympic Games.

 

"The 2009 sustainability plan brings achieving this goal closer to reality. WWF look forward to working with London 2012 on the next stage, engaging sponsors and audiences in creating a new Olympic and Paralympic movement for the planet."

 

David Higgins, the chief executive of the Olympic Delivery Authority (ODA), said: "We have made sure that sustainability is at the heart of this project from the outset and the 'green build' is on track.

 

"As we create the Olympic Park, cleaning the area of contamination, creating world-class new sports venues, thousands of new homes, new infrastructure, transport links and a new green space for Londoners that will remain many years after 2012, we are doing so in as sustainable way as possible.
 
"Whether it is in the design of venues, the innovative use of sustainable building materials, using water and rail to reduce vehicle emissions, reusing and recycling waste on site or planting thousands of new trees and plants, we are determined to minimise carbon emissions and leave a green legacy for industry to follow."
