The commission set up to monitor the environmental impact of the Games has announced; London 2012 has been the greenest Olympics ever.
The independent Commission for a Sustainable London 2012 said recycling and regeneration had been a success. But it said much more could be done to minimise the impact of future Olympic Games on people and the planet. Commission chairman Shaun McCarthy said London had set high standards for future Olympic host cities to follow.
Transport success
Previous Olympics have been criticised for the environmental damage they caused through waste, construction and transport.
Sustainability was at the heart of London's bid for the Olympics and the commission said organisers had largely succeeded in achieving it.
For example, the venues were told to be made of at least a quarter recycled materials - that included using disused gas pipes in the Olympic Stadium.
The Olympic Park was praised for regenerating a derelict area and benefiting wildlife, and the commission said it was amazed by the success of public transport.
But it said the challenges for future host cities were off the Olympic site, including the social ethics of some of the manufacturers and sponsors associated with the Games.
