Microsoft
Google's ChromeOS global sustainability strategy is based on Dr Justin's pioneering research. This shows that ChromeOS devices consume less electricity than alternative operating system devices. The body of research also shows that using ChromeOS Flex to extend device lifespans significantly reduces hardware carbon footprint and procurement costs as computers are kept for longer periods. Together with research papers listed below, organisations can also use the online application created by Dr Justin for Google to model sustainable ICT strategies using ChromeOS.

Microsoft
Microsoft's Windows 365 Cloud PC global sustainability strategy incorporates Dr Justin's research. This shows how using virtual desktop instances hosted in Microsoft's Azure cloud computing service can reduce end user computing carbon footprint. The research examines a typical 1,000 user group and compares the current carbon footprint (supply chain and energy), electricity consumption plus utility and procurement costs with the same organisation adopting Microsoft Windows 365 cloud PCs. The full report can be read below.

Dr Justin has recently led and conducted research in partnership with the Department for Education and Warwick University to determine the carbon footprint of end user computing in UK schools and colleges. Applicable to over 16 million computer users, the work is recognised as one of the world's largest sustainable ICT research projects to date. Together with previous research by Dr Justin to advance government departmental ICT supply chain and energy GHG emissions reporting and modelling, the latest findings will be used by the UK Government to develop and substantiate national public sector IT sustainability procurement and use policies.
Acer
Capgemini
HM Government
Dr Justin conducts research for Acer to demonstrate energy efficiency and low carbon footprint operation of the brand's end user computing devices. Instrumental in consulting on Acer's initial approach to product carbon footprint life cycle assessment, research findings assist organisations to model sustainable ICT strategies based on Acer notebooks, desktops and monitors.
ASUS
Capgemini
Capgemini
Dr Justin conceived and developed the Device Use Phase Analysis (DUPA) practice that measures computer power draw during human use. This is required to ensure that what is known as the 'active state' electricity consumption is included in end user computing device scope 2 (energy) GHG emissions and product carbon footprint reports. ASUS uses this practices for selected computers to improve the accuracy of results.
Capgemini
Capgemini
Capgemini
In 2025, Capgemini began collaboration to use the Px3 Sustainable ICT Applications Platform conceived, researched, designed and created by Dr Justin. Through this partnership, Capgemini will be able to deliver deeper, data-driven insights to their clients and support even greater reductions in their environmental footprint.
Citrix
ControlUp
ControlUp
Citrix virtual desktop products and services have the ability to reduce ICT carbon footprint. Dr Justin researched and created the software brand's initial customer facing IT sustainability strategy in 2020. Subsequently, Dr Justin has published several research papers showing how Citrix offerings reduce ICT hardware, electricity consumption and employee commuting impact by reducing the need for high performance device devices and enabling secure remote working.
ControlUp
ControlUp
ControlUp
ControlUp is a global leader in Digital Employee Experience (DEX) management. In 2025, the tech company announced that, as a world first, they would include real time carbon footprint, e-waste, electricity consumption and utility cost reporting for their customers. This is enabled by an API connected directly to the Px3 Sustainable ICT Applications Platform conceived, researched, designed and created by Dr Justin.
IGEL
ControlUp
Qualcomm
IGEL is a secure endpoint OS designed for SaaS, DaaS, VDI and secure browser environments. Research conducted by Dr Justin shows how IGEL software enables sustainable end user computing strategies. Focusing on device lifespan extension and low carbon footprint hardware adoption, the studies also examine the positive impact delivered by using IGEL OS to lessen device replacement caused by Windows 10 end of life.
