Energy reduction and decarbonisation


We continue to source and implement new technologies into our business which help to reduce carbon emissions. Operating around the globe, Allied Universal’s fleet comprises more than 19,000 vehicles of many different sizes and roles, from small patrol vehicles to armoured cash transports. It is our fleet that is responsible for around 75% of our core Scope 1 and 2 GHG emissions, and therefore the primary focus of our decarbonization efforts. For over a decade we have been installing telematics systems in operational vehicles to significantly improve fuel efficiency and reduce emissions, investing in driver skills training and behaviour monitoring systems, and where possible, introducing more efficient engine options and vehicle types into our fleet. Additionally, we continue to drive the integration of business intelligence applications into traditional patrolling operations, thus reducing vehicle use.

Road to Zero (Europe)

As part of a global partnership to explore low carbon solutions, Shell Mobility and Fleet Solutions is providing G4S in the UK with a countrywide public charging infrastructure for its growing electric vehicle fleet; and in 2023 will begin a program to install EV chargers at G4S managed facilities, including cash transportation branches, patrol and response depots, and care and rehabilitation facilities.

  • During 2022, 74% of all vehicles ordered in the UK were low emission vehicles. These include 10 state of- the-art electric cash transport vehicles, as part of a city-based trial; and 136 hybrid-electric powered patient transport ambulances, which will operate across the southeast of the country. In total 35% of the addressable fleet are now hybrid-electric or full electric low emission vehicles (62% including ordered vehicles).
  • In Europe, starting with the Netherlands, Shell is supporting G4S to implement the Accelerate to Zero program, a tailored roadmap for decarbonizing fleet operations.
  • In key markets, where the infrastructure permits, such as the United States, UK, Netherlands, Denmark and Belgium, we are exploring the use of electric vehicles in corporate car fleets and specific operational contexts.
  • Implemented global programs to ensure vehicles are well maintained, delivering safety and environmental benefits.
  • In collaboration with a valued customer in Belgium, we are executing mobile opening and closing rounds using bicycles.

Our Buildings

Allied Universal occupies a wide range of buildings across the globe, covering almost 10 million square feet. Our managed facilities include corporate offices, technology centres, cash processing facilities, employee accommodations and vehicle depots. Around 25% of our Scope 1 and 2 GHG emissions are generated by energy and fuel usage at these buildings, and we are continuing to carry our equipment replacement programs and explore opportunities for sourcing renewable energy.

Since mid-2020, all businesses in the UK, which represent 15% of our global electricity consumption, have procured electricity from certified renewable sources, saving c.7,000 t/CO2e over the past two years.

Supporting our customer objectives

As well as striving for a more sustainable business, by embedding carbon reduction strategies into our business, we are supporting our customers’ ambitions for a low carbon supply chain. By utilizing renewable energy sources in our operational delivery, embracing new technologies such as A.I. analytics or drone surveillance, or integrating the latest business intelligence applications into our service design, we are reducing vehicle use. With more and more of our security officers being technology enabled, they can capture and provide data directly back to customers thus demonstrating our efforts in this space.

In addition, we participate in leading climate reporting initiatives, such as the CDP Climate Change and Supply Chain Surveys, providing information to our customers. We are proud of our strong heritage of engaging with our clients to ensure their business continuity and the safety and security of their personnel and infrastructure in the even of extreme weather and other challenging geopolitical circumstances.

Reducing energy in our UK business

The G4S UK fleet utilises satellite tracking to enable real-time monitoring and feedback on driver behaviour, reducing traffic accidents and increasing fuel efficiency.
