Energy reduction - fleet

In order to provide our customers and their communities with a safe and secure environment, we utilise a fleet of approximately 22,000 vehicles, including security patrol vehicles, prisoner escort vehicles and armoured cash transportation vehicles. It is this fleet that produces some 61% of our carbon emissions and where we focus our primary efforts to reducing our energy consumption.

Since 2009, we have been introducing a range of fuel efficiency measures into our fleet management, from real-time monitoring of driver behaviour and eco-driver training to investing in new technologies such as solar cells to power ancillary systems, stop-start systems and vehicle replacement programmes to introduce lighter and more efficient alternatives G4S’ Retail Cash Solutions technology results in 40-60% fewer journeys by cash transportation vehicles saving on fuel costs and helping reduce traffic congestion and carbon emissions.


G4S occupies a wide range of buildings across the globe, covering more than 1.1 million square metres. Our facilities include corporate offices, employee accommodation, detention centres, industrial cash processing centres and vehicle depots.

Around 34.3% of our carbon emissions are generated by the energy and fuel consumption from these buildings and so we continually carry out a series of replacement programmes to implement lower energy environmental solutions wherever possible.
