The Chairman of the Commission for a Sustainable London 2012 has heaped warm praise on the London Games.
Shaun McCarthy said:
"I have no hesitation in confirming that London 2012 has delivered the most sustainable Games ever, and we congratulate the delivery bodies and all those who contributed to this excellent achievement.
"But we mustn't rest on our laurels - more could be achieved if London's lessons, both the good and the challenging, are heeded by others.
"London 2012 has raised the bar on sustainability, not just for future Olympic and Paralympic Games but for industry, and for the organisers of major events the world over - from music festivals to football World Cups. By being open to learning from these successes as well as the missed opportunities, future major projects could even outperform London 2012's sustainability achievements.
"The UK is hosting the Commonwealth Games in 2014, the Rugby World Cup in 2015, and the Olympic Stadium is hosting the World Athletics Championships in 2017 - what better way to deliver the legacy than by embedding leading sustainability practice in these events?
"I call on the organisers to pick up the sustainability baton and carry it forward, demonstrating to the UK public that we can rely on them to meet the spirit of London's sustainability achievements."
