Management of the live sites, London 2012's slow development of an energy plan and the organisers' failure to put messages of sustainability in the the opening and closing ceremonies all came in for criticism but overall the Commission for a Sustainable London 2012 gave the event a thumbs up.

Such was London 2012's success in delivering against its sustainability pledges the watchdogs are calling for future British-based festivals and sports competitions such as the 2014 Commonwealth Games, the 2015 Rugby World Cup and the 2017 World Athletics Championships to follow its lead.
