Following questions from Jenny Jones, a Green Party member of the London Assembly, he also admitted that decisions on the sustainability of the games depend upon the budget negotiations with the Government.
He said: As things stand at the moment, there are areas where the Olympic Delivery Authority (ODA) approach falls short of where I wish to be, particularly on waste, water and timber procurement issues.
You wont get a final decision out of the ODA until we have a final budget or somebody has come with the price. Thats why its important that we actually see the Government pick up the gap. If we fail to do that we might very well fall short of where we want to be in sustainability.
Livingstone added that he is pushing the Government to come with the funding for that gap, while he will follow the issue through as far as it will go.
Jones commented: Londoners were promised the greenest games ever, but the Olympics policies on energy, water use and sustainable timber are unambitious and deeply disappointing.
Strong environmental standards for the Olympics should be non-negotiable. The environmental commitments in the Olympics bid were among the key reasons that London won the games. They must not be jettisoned in an attempt to cut costs.
