Willmott Dixon has led the charge of construction companies on to the Sunday Times Green List, as the industry continues to prove its environmental credentials.
The Hertfordshire-headquartered contractor is listed as the third greenest company in the UK on the list, which will appear this Sunday.
Skanska is hot on its heels in fourth, with five construction-related firms in the top 20; and 10 in the top 30.
The Sunday Times compiled the list using the results of two surveys – one of employers themselves, and one of employees.
Willmott Dixon Group, which employs almost 3,000 people across the country, aims to be carbon neutral and send zero waste to landfill by 2012. It has used Formula One tyres on a school roof, and recycled denim and T-shirts as wall insulation.
Earlier this year the contractor welcomed famed sustainability campaigner Jonathon Porritt to the board of Willmott Dixon Ltd.
Willmott Dixon group chief executive Rick Willmott said: “To do so well at our first attempt is brilliant news for the business.”
He added: “What makes this accolade so special is that alongside the online survey, our detailed submission was subjected to a rigorous verification process. To be placed so highly after this scrutiny really does show how we are leading the sustainable development agenda for our industry.”
The other construction industry firms in the top 30 are: Skanska (4th), Carillion (11th), Morgan Lovell (14th), MCM Architecture (20th), Kingspan (21st), Johnson Tiles (25th), Wates (26th), Aggregate Industries (28th) and H&H UK (29th).
