These include measures for waste diverted from landfill, the recycled content of the building, energy performance ratings and a monthly environmental audit of all sites.

Carillion may have fallen down the list but it is still ranked the third greenest construction company. It's electricity and gas consumption have both fallen by more than 20% in the past year. The firm aims to halve its carbon emissions by 2010 against a 2006 baseline.
