We require our supply chain to tell us where materials have come from and ask them to provide details of the processes and people employed in producing them. This is so we know that the materials we use have not been produced through the exploitation of people or land. Our policy sets out a clear strategy for responsible sourcing, including short, medium and long term expectations.
We have set progressive targets for recycled content levels on our construction projects and regularly achieve over 20%.
Global warming potential (GWP)
To reduce the contribution we make to climate change, we require our suppliers to specify and use substances, (including refrigerants and insulants) with a GWP of less than five, where technically feasible.
Volatile organic compounds (VOCs)
We are seeking to minimise the impact of materials containing toxic VOCs sourced by Willmott Dixon directly and through its supply chain.
Polyvinyl chloride (PVC)
We consider alternatives to PVC with relation to environmental, economic and social impacts. Where PVC is required we will ensure that it is responsibly manufactured and disposed of.
All paper we use must either be recycled or, if virgin fibres are used, these must have been sourced under an approved and certified chain of custody.
We engage with manufacturers, suppliers and contractors to jointly develop strategies to reduce packaging on our projects.
Renewable and non-renewable materials
Renewable resources are those which come directly from the natural environment and which can be replenished. Timber is probably the most consumed natural material we use, and to ensure that this is sustainably grown and sourced, we only use timber and timber products which are certified as such by either FSC or PEFC.
A non-renewable resource is a natural resource which cannot be reproduced, grown, generated, or used on a scale which can sustain its consumption rate, for example, minerals and metals. We use these responsibly and wherever we can we ensure they can be recycled. We also encourage the use of non-renewable recycled resources.
