Climate Change & End User Computing

Over 1% of global GHG emissions are caused by end user computing device production and use

A forest the size of Argentina is required to remove this carbon footprint from Earth’s atmosphere every year

Making simple changes to your end user computing operations can significantly reduce both GHG emissions plus utility and device procurement costs meaning that sustainable IT is good for planet and profit.

As an example, comparing devices ahead of purchase by carbon footprint rather than simply ensuring they are energy and eco-label certified can reduce environmental impact by as much as 82%

Equally, extending device lifespans by 2-years can on average reduce supply chain carbon footprints by 40%

Almost 50% of organisations suggest a lack of data to support IT sustainability projects prevents success. With Px3 all barriers are removed.

Using Px3 applications our customers are accurately calculating and reporting end user computing scope 2 (electricity) and scope 3 (supply chain) GHG emissions, utility consumption and costs plus offsetting for over 5 million devices.

They are also transitioning to strategies such as low carbon footprint new devices or remanufactured devices by using our Dynamic Carbon Footprint device comparison tool.

Together we are realising the UN Sustainable Development Goals of responsible consumption and driving climate action via sustainable IT

So why not avoid green wash and trust the only applications suite scientifically validated to drive climate action with sustainable IT?

FAQs

Why is Px3 IT carbon footprint approach more accurate than others?

Other computer carbon footprint companies use computer energy consumption benchmark data that excludes electricity consumed when humans use computers. Instead their data focuses only on low power modes such as off, sleep and idle which is counterintuitive as computers are purchased to be used. Considering that computers experience the highest level of electricity consumption when subject to human-computer interaction, excluding what is known as the 'active state' from electricity consumption and associated GHG emissions causes considerable errors. Px3 is the only company that has developed a methodology that enables the inclusion of the active state. The method and applications Px3 uses were developed during PhD research with the University of Warwick computer science faculty by Dr. Sutton-Parker, a leading scientist in the field of sustainable IT. As such, unlike competitive offerings, our results are founded in science, tested rigorously in the field and peer reviewed by leading academics and scientists.

Do you work with companies and brands that I recognise?

Px3 conducts IT carbon footprint consulting for many of the world's leading information technology companies, national governments, plus brands that you will use every day. See our 'trusted by' logos or our case study pages for more details. We have currently calculated GHG emissions for over 5m computers.

Can I calculate computer GHG emissions for free?

Yes. While we offer chargeable sustainable IT services, we also offer a free of charge online application to get you started. Simply go to https://itcf.px3.org.uk and register. Once your account has been activated you will be able to use the application to generate an average electricity consumption (kWh/y) value, a carbon footprint (kgCO2e) value and an offset value (trees) for all of your end user computing devices (such as notebooks, desktops, monitors etc.) based on how many years you intend to keep the devices and where in the world you will use them.

Do you have an application to compare computers by carbon footprint to help our procurement strategy?

Yes. It's called the Dynamic Carbon Footprint application. It enables you to rank computers by carbon footprint and make the right choice based on sustainability as a criterion. The application is unique as it enables you to select how long you may keep devices for and where they will be used. This is important as manufacturer reports don't allow this. Instead they determine retention and location periods, such as 3-years and 'the USA', while you may keep devices for 5-years and be based in Europe where electricity is less carbon intensive. As such, the application assures that your decisions are based on data relevant to you and your organisation. This application is a paid subscription and can be purchased at https://px3.org.uk/applications/compare/

Can I speak to an expert without being 'sold to'?

Yes. We were founded as a research organisation and do not employ selling tactics. Simply go our contact page at https://px3.org.uk/contact and ask to speak to a Px3 consultant. We offer a 30 minute free of charge discussion to help you to understand how sustainable IT can not only reduce your organisation's carbon footprint but also reduce associated costs such as electricity consumption and procurement through efficiency and longevity.
