Managing our resources responsibly
We recognise our responsibility to steward the planet’s resources with care and consideration. We’re committed to improving our efficiency and reducing our environmental impact to maintain a secure, reliable, and sustainable business for good.
We are working to ensure all aspects of responsible resource management are embedded throughout our product lifecycles and integrated into our business operations. Our immediate focus is to deliver Energy Action Plans to reduce the energy intensity of our operations and to improve awareness across the organisation to maximise opportunities to improve efficiency and eliminate energy leakage.
Within our [FY25] sustainability strategy, responsible resource management has been identified as a core enabler of operational excellence and long-term value creation.
Sustainability in action
Through collaboration with our supply chain, we have applied a new and innovative methodology which will enable around 90% of the dismantled submarine structure and components to be reused or recycled – leading the way for the UK, providing a proven approach for recycling the current UK decommissioned fleet of submarines.
Read about how we are innovating to deliver high levels of recycling for submarine dismantling.
We have invested in a solar power system, consisting of a 150-kilowatt hybrid inverter and 198 x 550-watt solar panels, at one of our largest operational hubs in South Africa. Since its installation, it has generated 100,489 kWh of electricity, reducing our CO₂ emissions by 109.73 tonnes. The system not only reduces our reliance on the grid during the day but also integrates battery storage to ensure power availability at night and during power outages, effectively reducing the need for diesel-powered generators.

Our hydrogen derived from wastewater project – a pioneering initiative aimed at developing radical fuel-switching technologies to support the decarbonisation of our Devonport facility and the wider maritime sector – won the Net Zero Resource Efficiency category at the MOD’s Sanctuary Awards in 2025.
The project focused on demonstrating the feasibility of producing sustainable hydrogen fuel from contaminated wastewater.
