Costain, the infrastructure solutions company, has been awarded the Green Apple award for its efforts in reducing the carbon footprint of its works on the M6 motorway. The Costain Smart Motorways Alliance project successfully reduced emissions by 38% in both the construction plant and van fleet. The project achieved this by implementing innovative enhanced idling sensors and providing behavioral training to reduce vehicle idling on site. The use of trackers in site vans also contributed to a reduction in van idling by around 25%, resulting in a decrease in carbon emissions and cost.
