London shows the world how to host a greener, more sustainable Olympics.
From the outset of the project, the Olympic Park has set new standards in sustainability, including the delivery of lightweight venues, the recycling or reuse of waste materials, using concrete with a high recycled content, and delivering materials by rail or water. We have achieved new standards for a project of this size and scale and have raised the bar for the industry.

LONDON, UK, July 31, 2012 (ENS) – The London Organizing Committee of the Olympic Games has met the vast majority of its sustainability targets, says the United Nations official in charge of helping Olympic Games host cities produce events that protect the environment and make smart use of their resources.
The whole environmental sustainability agenda is incredibly important for these buildings,” [architect] Sheard says. Forty percent of the 80,000-seat venue’s concrete is recycled aggregate, and the stadium is one of the lightest of its size. “If you build less, you’ve got a smaller carbon footprint,” the architect says. Built with just over 10,000 tons of steel, the stadium is far lighter than similarly sized buildings, which normally require five to ten times as much.
