The mining, manufacture and supply of materials used in construction, such as concrete and steel, impacts both the environment and communities living near our project works. Sourcing sustainable materials and methodologies can create benefits such as reducing the use of non-renewable resources and lowering emissions.
Reusing existing materials (such as spoil from tunnel excavation works) can also reduce the number of truck movements around project sites.
Given the scale of our construction projects, we are developing a circular economy strategy to help us integrate sustainable materials into our construction projects and road-maintenance works.
As part of this strategy, we’re also working with our suppliers with the goal of creating a more sustainable supply chain.
