At Harwell, we have a vision to develop a sustainable Campus for world-class science & innovation.

Our Areas of Focus

Harwell has identified seven focus areas, aligned with the UN Sustainable Development Goals, to turn our sustainability vision into measurable action. Our ambitious roadmap sets key milestones for this decade to tackle the climate and environmental crises and create a prosperous, net-positive future.

Sustainability starts with all of us

Our Sustainability Handbook provides practical guidance to help everyone at Harwell make more responsible choices. Discover simple ways to reduce environmental impact, support our sustainability goals and contribute to a greener, healthier campus.

How

Nature Recovery in Action

We’re protecting Harwell’s natural environment by preserving habitats, enhancing biodiversity, creating green spaces and preventing pollution.

Our Woodland Habitat Improvement Project demonstrates this commitment, winning the 2023 BIG Biodiversity Challenge Habitat Creation Award and Gold at the International Green Apple Awards.

Towards Sustainable Travel

We aim to encourage active travel choices and facilitate access to low emission options to commuters.

This is being achieved by:

  • Making sustainable travel options available to Campus staff and visitors (e.g., public transport, cycling routes)
  • Providing incentives for choosing greener travel choices (e.g., discounted bus season ticket, free bike loan)
  • Delivering the infrastructure for the future of mobility (e.g., EV charging, cycle hub)

    In 2024, Harwell was recognised at the Oxford Climate Awards for its continuing efforts towards sustainable commuting.
Towards Social Value

We aim to make a lasting positive contribution to communities & the local economy.

This is being achieved by:

  • Delivering a Community Employment Plan (CEP) and measuring Social Value on new developments
  • Encouraging our supply chain to employ a local & diverse workforce, and to use local businesses, SMEs and VCSEs
  • Providing financial and/or non-financial support to local charities and community groups
  • Inspiring young people through STEM and showcasing careers in construction while creating opportunities for apprentices and work experiences

Towards Circularity

We aim to shift the development of our Campus towards circular economy, maximising the value of materials and natural resources whilst avoiding waste.

This is being achieved by:

  • Avoiding waste & maximising Reuse & Recycling
  • Securing Zero Waste to Landfill
  • Applying Sustainable Procurement principles when selecting our Suppliers
  • Procuring responsibly sourced construction products & materials such as FSC/PEFC certified timber
  • Specifying construction materials with high recycled content
  • Designing buildings for disassembly to allow materials to be re-deployed at their end-of-life.
Towards Net Zero Carbon

We aim to transition our built environment towards Net Zero Carbon, halving greenhouse gas emissions by 2030.

This is being achieved by:

  • Developing and delivering low carbon buildings, with a focus on reducing upfront embodied carbon and operational energy demand
  • Quantifying & reducing the carbon emissions from managed buildings
  • Enabling the reduction of carbon emissions from leased assets, existing and future
  • Driving the reduction of carbon emissions from the supply chain (goods & services)
  • Facilitating the integration of on-site renewable energy generation (e.g., solar)
  • Procuring electricity backed by Renewable Energy Guarantees of Origin (REGOs)
  • Phasing out fossil fuel as primary energy source (e.g., natural gas, diesel)
Our Living Lab for Climate Action

Tackling the climate crisis is a key part of the research and innovation we conduct on campus.

To enable it, Harwell Campus has established a Living Laboratory which will allow new technologies to be piloted in a real-world environment – embedded into the onsite infrastructure.

The Harwell Living Lab will accelerate the adoption and accessibility of pioneering technology solutions including connected and autonomous travel, green fuel solutions, and integrated energy systems.

Furthermore, by drawing on expertise from its thriving Energy Tech Cluster, which has grown to 80 organisations including the Faraday Institution, Harwell will remain committed to supporting the UK in reaching national carbon targets and reducing greenhouse gas emissions to net zero by 2050.
