Climate change is one of society’s greatest challenges. There is a growing recognition of the impact of climate change on the future success of businesses. This includes, for our business, the physical impacts of climate change and the impacts of transitioning to a low carbon economy.


Our climate change strategy

Solving the challenge of climate change requires all of us to act together, with urgency. One of the focus areas of our sustainability agenda is to play our part in addressing the significant and lasting impact of climate change. As a defence and security company, technology is at the core of our business and we must leverage this while progressing our ambition of net zero greenhouse gas emissions. Our goal is to develop and implement a long-term strategy that reduces the impact of our activities, supply chain and the products on the environment. We are progressing our net zero ambition and are developing milestones in line with the UN Race to Zero via the Business Ambition for 1.5°C pathway. Part of our strategy is to reduce our energy consumption, purchase renewable energy and develop on-site renewable electricity supplies where practicable.

Race to Zero  

A year ago we joined the United Nations’ Race to Zero campaign, making progress with more to go.

Electric drive systems

More than 14,000 of our electric-hybrid systems are in operation, saving the environment from more than 30 million gallons of fuel emissions and 335,000+ tonnes of Co2 Read more

Our ambition to achieve net zero


We strengthened our net zero pathway by signing up to the UN Race to Zero via the Business Ambition for 1.5°C campaigns. Our UK business intends to submit net zero milestones for the Science Based Targets initiative during 2022. We will look to extend this to other parts of the Group as we mature the development of our net zero roadmap and our related internal processes.


To play our role in solving the challenge of climate change, we launched our ambition for net zero during 2021 setting ourselves the target of:

BY 2030

Achieving net zero greenhouse gas emissions across our operations (Scope 1 and 2) by 2030. We aim to do this by reducing our emissions as a minimum in line with the 1.5°C pathway.

BY 2050


Working towards a net zero value chain by 2050.

Our net zero programme


During 2021, we progressed our net zero programme by developing a net zero roadmap for the Group and scoping the change management, governance, planning requirements and assessed the level of investment which we will need to transition to a net zero organisation.


Setting environmental targets and initiatives at business level

The nature of our business makes it challenging to set global emissions reduction targets. Therefore, we set and implement environmental targets and initiatives at business level, to contribute to an overall reduction. Businesses set objectives to reduce energy used, water consumption and the generation of waste, emissions, and other discharges.
