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.
Carbon emissions
Our direct operations have a relatively low carbon intensity, which contributes to our proportionally small environmental impact on a global scale.
Despite this, the threat to the natural environment and social infrastructure from climate change is an important and ongoing issue for our organization, customers, employees, and communities.
G4S has committed to achieving net-zero carbon emissions by 2050.
GHG Emissions
We follow the GHG Protocol to measure our greenhouse gas emissions - focusing on the operational emissions (scope 1 and 2) for businesses over which Allied Universal has
financial control. In addition, during 2024, we measured a range of scope 3 emissions across our business:
Global: Employee business air travel
UK and Ireland: Material scope 3 emissions categories
Recognizing the complexity of the organization’s indirect emissions, and the emerging legislated reporting requirements in both the United States and Europe, we began a global scope 3 GHG emissions assessment in 2024. Collaborating with TRC, this in-depth analysis will pinpoint key emissions categories, refine data collection and assumption methodologies, and ultimately help produce our first comprehensive global scope 3 emissions inventory in 2026, reporting on 2025. The companies that reported data in the 2024 GHG measurement represent 96% of Allied Universal’s global business across a 12-month period. This level of measurement, covering each of our main business types, allows reliable calculation of the total GHG emissions for 100% of the organization.
