energy reduction and decarbonisation


In order to provide our customers and their communities with a safe and secure environment, we utilise a fleet of approximately 15,000 vehicles, including security patrol and armoured cash transportation vehicles. It is this fleet that produces some 62% 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 technologies such as solar cells to power ancillary systems and vehicle replacement programmes to introduce lighter and more efficient alternatives including hybrid and electric vehicles.


G4S occupies a wide range of buildings across the globe, covering more than 750,000 square metres. Our facilities include corporate offices, employee accommodation, detention centres, industrial cash processing centres and vehicle depots.

Around 30% 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.
