Dan Epstein, Olympic Delivery Authority’s (ODA) head of Sustainability said: “The construction of the new permanent venues and infrastructure and the creation of the largest new urban park in Europe for 150 years will require large amounts of aggregate materials.

This is an essential contract for the 2012 project and it is important that it has sustainability at the heart of its plans.” 

The ODA required competing companies to emphasise their 'green' credentials and their plans for meeting the ODA's sustainability targets.

Specifically, tenderers were asked to ensure that they either meet or exceed the following targets:
* At least 25% of aggregate content to be recycled material
* At least 50% of materials, by weight, to be transported to the Olympic
Park by sustainable methods

Aggregate Industries were able to commit to transporting 99% of aggregate materials via sustainable transport methods, surpassing the ODA's target of 50%. Approximately 74% of the aggregate materials will be transported by rail and 25% by water, with only 1 per cent transported by road for specialist materials which do not have established rail and water links.
