Costain wins environmental award for reducing emissions by nearly 40% on M6

Costain, the infrastructure solutions company, has won a Green Apple award for significantly reducing the carbon footprint of their works on the M6 motorway.

The Costain Smart Motorways Alliance project on the M6, between J21a and 26, successfully reduced the carbon footprint in both the construction plant and van fleet, cutting emissions by 38%. Emissions from vehicles ‘idling’ on site was reduced from 56% to 18%, between the start of 2022 and June 2023, using innovative enhanced idling sensors and behavioural training. Site vans were fitted with trackers and between February and June 2023, this reduced van idling by around 25%, with associated carbon emissions and cost falling, on average, by 35kg and £4.19 per driver.

Switching from diesel fuel to hydrotreated vegetable oil (HVO) in February 2022 reduced carbon emissions by 679tCO2e; which is the equivalent of 27,000 trees absorption of CO2 in one year.[1]

Catherine Warbrick, Costain’s executive lead on sustainability said: "I’m really proud of the work the team has done on the M6, and the amazing results they have achieved. Costain aims to be a force for change and to safeguard the future of our planet for generations to come. Projects like this one on the M6 demonstrate our commitment to finding solutions to tackle the environmental challenges facing our planet.”

The Green Apple Environment Awards were established in 1994 as an annual campaign to recognise, reward and promote environmental best practice. Entries are invited from any company, organisation, community or individual that is helping the environment. It was the first scheme to be accredited as an official feeder scheme into the European Business Awards for the Environment and it is now the only official feeder scheme into the global Green World Awards, which are held in a different country every year.

This stretch of the M6 extends from the Croft Interchange at junction 21a, just north of Warrington, to the Orrell Interchange at junction 26 near Wigan.
