On key issues such as energy, waste and the use of resources, as well as the effects on public health, the management of London 2012 has fallen short, said WWF and BioRegional, two green campaigning groups.
They found that the Games would neither be zero carbon nor zero waste, with not enough new renewable energy generated to cover the amount consumed, while many opportunities have been lost – which may be in part owing to the practices of the sponsors and major commercial partners – to use locally grown food and Fairtrade products. Air quality is also likely to fall short of targets.
Sue Riddlestone, executive director of BioRegional, who was involved in drawing up the original strategy, said: “London 2012 has set the sustainability bar high for future summer Olympics [but] there were some promises made in 2005 which London 2012 didn’t keep, even though we know they tried. We were especially disappointed about the failure to meet the renewable energy targets. So the journey to deliver a sustainable Olympics will continue.”
But the London Organising Committee of the Olympic and Paralympic Games (Locog) defended its performance, saying that it had met the majority of its targets, even though the blueprint for the environmental aspects of the games had been published eight years ago and that expectations for environmental sustainability had increased in that time.
David Stubbs, head of sustainability for the Games, told the daily Guardian: “We have kept the spirit, and in most cases the letter, of what was promised, and we will leave a long-term legacy that is positive, environmentally. To use a footballing analogy, we did not necessarily win every match but we did win the league.”
He said that the committee had been thwarted in some of its attempts to improve the environmental performance – for instance, in trying to set up a wind turbine close to the main Olympics site in east London, and that its attempts to ensure a legacy of drastically cutting the waste sent to landfill from the sites proved impossible to fulfil because of local conditions beyond the organisers’ control.
The report found that the games would score well on some environmental indicators, such as public transport and ensuring the upkeep of local natural habitats and wildlife.
David Nussbaum, chief executive of WWF-UK, which co-wrote the report, said: “We are pleased that London has set the bar higher and has moved faster than previous comparable events. But as batons are passed in the next few weeks to those responsible for delivering a legacy from London 2012, and for putting on future Games, we expect that a stronger commitment to sustainability will continue.”
Riddlestone added: “It is important that all the great things which London 2012 have achieved and the lessons learned are passed on and that a commitment to sustainability is a key criteria by which the 2020 summer Olympics bids are judged.”
