Carbon emissions

G4S recognises that the threat to the natural environment and infrastructure from climate change is an important and ongoing concern for our organisation, our customers, our shareholders and our employees.

Alongside the risks faced by people and infrastructure from climate change are the challenges presented by global economic conditions. We recognise that these threats are an important and ongoing concern for our organisation, customers, employees and communities. Managing fuel costs and the impact of climate legislation through programs to improve the organisation’s energy efficiency and reduce its environmental impacts are important to the continuing effectiveness and sustainability of G4S.

Beginning with our businesses in the UK and Ireland, we have committed to achieving net-zero carbon emissions, as defined by the net-zero standard, by 2050 or sooner. In 2022, G4S UK and Ireland committed to the Science Based Targets Initiative (SBTi) to reduce its emissions in line with climate science and, subsequently, published the details of its net-zero strategy and science-based targets for UK and Ireland. G4S has submitted its UK and Ireland targets to the SBTi for validation.

Building on the lessons learned from our experience in the UK and Ireland, we will undertake a review of our current global approach to environmental impact and reporting, with the aim of developing a new climate action strategy. A program to review our approach and develop a full road map and science-based targets to achieve this ambition will commence in the future.

GHG Emissions

We follow World Business Council for Sustainable Development and World Resources Institute’s Greenhouse Gas Protocol to measure our Scope 1 and 2 emissions - vehicle fleet, fuel, refrigerants, and electricity usage for Allied Universal businesses (including G4S) over which the company has financial control. In addition, we measure global Scope 3 emissions from employee business air travel, and the material scope 3 emissions of our businesses in the UK and Ireland region.

The businesses that reported data in the 2022 GHG measurement represent 96% of Allied Universal’s global operations across a 12-month period. This level of measurement allows reliable calculation of the total GHG emissions for 100% of the organisation.

We have made considerable progress to date, with a reduction of some 18.4% in carbon emissions since 2019. (This figure includes the impact of the divestment of the majority of the Cash Solutions businesses and the Covid-19 pandemic.) We have taken steps to reduce the energy footprint of our fleet (Fleet to Zero project) and facilities and to reduce business travel through new technology.
