Sustainability & Supply Chain

Colas Rail are committed to a proactive sustainable development approach in our purchasing, which is an important component of our activities.

We embedded sustainability into our business processes and behaviours and consider our impact on the environment, and local communities aiming to create a circular economy. We acknowledge that we need the support of our supply chain as they are intrinsic to our performance and can deliver resource efficiencies, low carbon solutions and reduce our whole life impacts but only if they have the support, knowledge, capability and capacity to do so.

Why a Partner?

We will embrace being a Partner in the School firstly as it allows us to collaborate with other industry partners, secondly because our suppliers are supported by the school and work with us on our sustainability journey and thirdly to keep our staff updated on all relevant issues utilising the vast Supply Chain Sustainability School resources.
