Our planet does a lot for us: it cleans the air we breathe, protects us from flooding, provides us with food and natural resources.

All essential elements for our everyday lives. However, climate change is putting increasing pressure on our planet and its ability to provide these services, whilst also causing more frequent extreme weather, loss of biodiversity, erosion of soil, and increased pollution.

We need to both reduce our contribution to climate change and adapt to our changing climate, to protect the lives and livelihoods of people and communities. Valuing nature and promoting resource efficiency are key to this effort. By prioritising sustainable practices and responsibly managing our natural resources, we can mitigate environmental impact and ensure that the vital services our planet provides are preserved for future generations.  

As a business we are committed to accelerate our action; doing more with less and playing our part to address the climate and nature emergencies.  


Climate action – we will reduce carbon emissions and work with clients to build resilient infrastructure against the effects of climate change. 


Valuing nature – we will work to protect and enhance biodiversity by managing nature risks and enhancing green spaces. 


Resource efficiency – we will work with our supply chain to use resources in a sustainable way throughout a project’s life cycle. 

Through Our Planet pillar, we prioritise strategic initiatives which drive climate action, value nature and encourage resource efficiency. Our strong focus on these topics supports our objectives to reduce our own carbon footprint, as well as that of our supply chain; protect and preserve the natural environment; and manage waste and water effectively. This is how we drive our purpose to sustainably deliver infrastructure that is vital to the UK.
