The news that the Olympic Delivery Authority’s business network will help companies across the UK compete for London 2012 business opportunities is a welcome announcement.

In my position as chair of the Commission for a Sustainable London 2012, I wholly approve of the open competition of more than 75,000 Games-related future business opportunities worth an estimated £6bn. Our expectation is that the companies that will be seeking this business will ensure that sustainability requirements will be embedded in every tier of the supply chain.

Shaun McCarthy, chair, Commission for a Sustainable London 2012
