Our carbon emissions

G4S UK has committed to achieving net-zero emissions by 2050, in line with the international Paris Agreement goals and the UK Government’s target. In addition, G4S has also set science aligned targets to achieve near-term emission reductions across its value chain for UK operations, which are aligned with the SBTi’s methodologies.


By 2030, G4S UK will:

2020 Baseline:

► Reduce absolute Scope 1 & 2 GHG emissions by at least 42%

► Reduce absolute Scope 3 emissions by 25%* 

(*) * c.80% of UK Scope 3 emissions have been generated by our supply chain

By 2050, or sooner, G4S UK will meet all net-zero global targets.

   t/CO2e market based  2022  2021 2020
   Scope 1 and 2  22,168 21,541 30,457
   Scope 3*  119,395 129,491 132,802

We use Green House Gas protocol methodology to undertake a measurement of our Scope 1 and Scope 2 carbon emissions – vehicle fleet, fuel, refrigerants, and electricity usage for G4S occupied businesses over which we have operational control on an annual basis. We also calculate the material scope 3 emissions of our businesses in the UK.
