The Commission for a Sustainable London 2012 found that the transport system during the Games delivered an excellent service and said London 2012 should be praised for being the first Games to offer a fully comprehensive mobility service.
It also found that comprehensive public transport options and effective planning meant that the logistical operation for the Games was delivered with minimal disruption to Londoners.
It came to the conclusion that another Games success story was the food, with a wide variety of healthy, sustainably sourced, affordable meals available at most London 2012 venues, driven by the development of the London 2012 Food Vision - a first for major event catering.
The Chairman of the Commission for a Sustainable London 2012 has heaped warm praise on the London Games.
Shaun McCarthy said:
The London Olympics have been named the most sustainable Games ever by an independent watchdog. The Commission for a Sustainable London 2012 praised the Games' recycling and transport policies - and said they could provide a model for future sports events.
These photos demonstrate the phenomenal transformation that has occurred at a former Victorian pumping station in Hackney.
The Grade II listed building is now an indoor climbing centre that is winning awards for its sustainability.
Later today, ITV London will be getting a tour of the Castle Climbing Centre in Hackney, which has recently been recognised at the Sustainable City Awards.
The indoor climbing centre is housed in what was once a Victorian pumping station.
The building is energy efficient, and a patch of waste ground at the back has been transformed into a market garden, which grows organic produce.
