London of the UK will be the focus of the world’s attention between July and September 2012, when the city will host the 30th of the International Olympic Games. The city has placed sustainability at the heart of its bid for the event and The London 2012 Sustainability Plan has been produced to illustrate how such a bid will be carried out on time. It is structured according to five priorities: climate change , waste , biodiversity , inclusion and healthy living – all of which will be addressed throughout the Olympic construction period, during the Games, and in the future legacy the event will leave behind.
