Securing our environment

Alongside the risks faced by people and infrastructure from climate change are the challenges presented by the economic climate.

Managing fuel costs and the impact of ‘carbon taxes’ through programmes to improve the group's energy efficiency and reduce its environmental impacts are important to the continued effectiveness and sustainability of our business.

We recognise the impact that our business activities can have on the environment and are committed to managing this impact in a responsible manner. Through our climate action programme we measure, report and reduce the intensity of our environmental impact. We have partnered with our customers, employees and suppliers to invest in energy efficient technologies and work to reduce waste and water consumption.

We are very proud of the progress we have made and the steps we have taken to develop an environmentally sustainable company by increasing our energy efficiency and reducing our environmental impact through new ways of working.

Climate change

There is now broad recognition that climate change is impacting the natural environment and that nations and people around the world could face severe consequences. Nations are responding to the threat of rising sea levels with contingency plans and resilience measures. The populations of less developed countries will suffer the results of climate change worst, and many will suffer earliest. 

Crop cycles are changing as climatic conditions change, displacing the communities that rely on their yields or forcing them to develop other crops, and possible subjecting them to poverty. Food security in fragile economies will be impacted by these agricultural changes and this could lead to conflict for resources, particularly water. The supply chains of multinational corporations whose operations are dependent upon crops and agricultural produce will be adversely affected. 

This is not just a future threat: it is apparent in the world today. Governments and multinational corporations will be required to secure their food resources and supply chains, requiring innovative security solutions by companies such as G4S.


  • G4S total carbon footprint in 2015 was 522,901 t/CO2e
  • Achieved a carbon intensity of 77 t/CO2e per £m of revenue in 2015, representing a reduction of 4.6% since 2014
  • Measured 52% of the waste generated by the group, totalling 9,298 tonnes of mixed waste with 32% diverted from landfill
  • Measured 74% of the group’s water usage with a total consumption of 1,917,196 litres
  • Increased use of video conferencing and virtual meeting technology has helped us reduce the carbon emissions generated by our business air travel by 6% since 2014
  • Continued to invest in telematics technology to monitor driver behaviour, leading to reductions in fuel usage and maintenance costs, as well as improving driver and road safety. At the end of 2015, some 4,700 of our cash solutions vehicles had been fitted with telematics devices
