Demolition of the main 2012 London Olympics stadium after the games has been put forward as an option following concerns about its long term costs.
However, the London Development Authority and the Mayor of Londons office were keen to stress that this was only an option and not a plan.
The future use of the stadium has not been secured as no one has yet confirmed they will take it over after the games.
An LDA spokesman said: The LDA is responsible for what goes on at the site after the games. It has a duty to examine all the options no matter how likely or unlikely. The options for the main stadium are in double figures. The demolition option has come from the possibility that if a premiership football club liked the site it would have to demolish the stadium and rebuild a football ground. In reality this option is probably too expensive so its unlikely.
There are no plans to demolish the stadium and the LDA is working towards the three sports use within the 25,000 seat stadium.
London Assembly Green Party member Jenny Jones added that demolition of the stadium would damage the London Olympics green credibility. She said: Londons Olympic organisers said they would minimise the energy which goes into providing materials for 2012 venues. Demolishing and rebuilding the biggest of those venues after the games makes a mockery of efforts to provide sustainable stadia.
She said the environmental and sporting legacy appeared to be under threat from the need to cover costs.
However, a Mayor of London spokesman said: "The Mayor has made it clear that he envisages a long term future for the Olympic stadium. Expensive facilities should not be built unless they have a viable future. That's why he is determined to play his part in finding a suitable use for the big ticket London venues beyond the 2012 games.
