A consortium made up of green organisations, Forum for the Future and the London Sustainability Exchange, together with auditor Pricewaterhouse Coopers, has been appointed by the Greater London Authority to monitor sustainability on the 2012 Olympic Games.

The team beat off competition from other international consultants, including Accenture and Environmental Resource Management, to secure the 2012 sustainable development assurance framework deal.

The team will work with the mayor’s London Sustainable Development Commission 2012 subgroup, which is also charged with monitoring the sustainability of the games.

The two groups will monitor the design and construction of the Olympic facilities, the staging of the Games, the regeneration of the Lower Lea Valley, and other contributory programmes. They will report to the Olympic Delivery Authority’s executive management board and the ODA board.

The news comes as the mayor last month launched a search for a sustainability champion to head the LSDC sub group. The chair, who is expected to be appointed in October, will receive £500 a day, for up to 130 days a year over three years.

Critics have argued that this is too little too late. One source said there were not enough resources supporting the job to make it meaningful. The source said: “The contract for the chair is for only two days a week to co-ordinate the monitoring of the whole of the Olympics. It’s ridiculous.”
