Winner

BYRNE BROS (formwork)

In today鈥檚 economic climate contractors might be tempted to take their eye off the sustainability agenda, but this isn鈥檛 the case for Byrne Bros, which over the past 18 months has refused to compromise its environmental commitments. The firm received ISO 14001 certification in 2007 and since then has been targeting waste, It now diverts 95% of its waste from landfill. But it鈥檚 the carbon emissions arising from its products and transport fleet that can鈥檛 be ignored, and the judges were impressed by the strides it has taken in this area. During the past two years the company has managed to reduce the embodied carbon of its concrete mixes by 50%. The renovation of its transport fleet has reduced emissions by 4% and it is targeting 10% next year.

Highly commended

Willmott Dixon

Willmott Dixon Group has set itself some tough sustainability targets, including delivering zero waste to landfill by 2012. The best way to achieve them, it believes, is from the boardroom down and it has put in place online training modules to spread the work. The firm is also on the core task group developing the UK Green 黑洞社区 Council鈥檚 Code for Sustainable 黑洞社区s and is helping subcontractors develop their own environmental management systems: 36 signed up by June 2009 and a further 80 will join them by the end of the year.

NG Bailey

How a building looks is no longer important; it is how it operates that counts. This is a bold statement but it underlines NG Bailey鈥檚 attitude to sustainability. As a firm responsible for designing, installing and maintaining primary energy-using systems, such as lighting and air-conditioning, the firm is well placed to have an impact on energy use. It has also embarked on a campaign to reduce its own carbon emissions by 5% every year. It now monitors the carbon consumption across its own estate and has introduced technologies, such as video conferencing, to ensure it meets its target.
