What people say about us

We’re already using the Px3 Compare app and it is golden. So far it seems they have included more or less exactly the filtering options that makes sense, which is great! The ability to select region of use – which I imagine is a major USP for the tool – is particularly useful. As far as I know there’s nothing like it out there and as the list of devices grows I can’t imagine why companies would go anywhere else to get CO2e information for their hardware inventory and purchasing decisions.

Kjetil Neergaard, Green Tech Manager, Strawberry Hotels, Norway

“Sustainability is at the heart of Google and Chrome OS. It is so important that we ensure we have a solid, science-based validation of the benefits our solutions can offer. That’s where Px3 come in. They are an independent, research-based company who provide analysis and benchmarking of the environmental impact of IT and workstyles. We have used their services to benchmark the sustainability benefits of Chrome OS, evaluate the impact from customer deployments, and create calculators to help our teams compute the sustainability impact of our product. Their research and contribution has helped to shape our approach to sustainability at a global level.

Michael Wheeler-Wyatt, Director Chrome Enterprise EMEA, Google

To manage towards a goal of Net Zero emissions we first needed to understand where we are today. This research work by Px3 provides a starting point for us to now aim to drive down the emissions from the DWP IT infrastructure to meet the Greening Government commitments.

Tony Sudworth, Sustainability Lead, DWP Digital

Px3‘s report gave us the actual figures and benchmarked a 32 percent reduction in energy with the move to Citrix and Acer Chromebooks – building on previous Px3 research about Chrome OS and energy savings. We received clear metrics from actual energy usage – that way, we have a level of assurance and confidence that we can validate our sustainability objectives.

David Grasty, Corporate Head of Digital Strategy & Portfolio, Royal Borough of Kingston and Sutton Councils

Acer’s goal is to be the leading sustainable device manufacturer in the industry and to support our customers to deliver meaningful change aligned to CO2 reduction.  Achieving our sustainability goals requires partnerships industry wide and also importantly with independent experts like Px3

FAQs

Why is sustainable IT important?

There are three great reasons to adopt sustainable IT. 1) Information technology generates as much as 5% of global greenhouse gas emissions. Using the Px3 tools to calculate and reduce IT carbon footprint, customers avoid over 30% IT GHG emissions. 2) Sustainable IT strategies often reduce utility and capital costs as computers become more energy efficient and are replaced less often. 3) New legislation such as CSRD requires companies to report the carbon footprint of capital owned goods. This includes IT such as notebooks, desktops, tablets and monitors. The Px3 reports enable companies to calculate and report the GHG emissions instantly.

Why Px3?

Px3 reports and applications are uniquely backed by science. Created during PhD research with the University of Warwick, the results are the most accurate on the planet. In fact, Px3 was the first company in the world to produce end user focused tools of these kind.

Do many organisations use Px3?

Yes, our applications are used by over 1,000 organisations across the globe. IT giants such as Google, Microsoft and ControlUp also use ours tools to help customers model sustainable IT baseline reports and strategies.

How long do reports take to produce?

The time to produce either a baseline or strategy report averages at around 5-10 minutes. Based on your data input (such as a list of what computers you have) the report will be calculated by our systems and emailed to you as a PDF.

What’s included in the ‘Calculate’ baseline report?

The report contains headline executive summary details including carbon footprint by total and scope such as electricity and supply chain. Plus electricity consumption and cost together with equivalent values such as how many trees are required to remove the resulting carbon from Earth’s atmosphere. The in depth table and graphs that follow concentrate on showing what equipment you have by type (e.g. desktops) and what the average impact is. There is also a section to quickly show which equipment is causing the greatest impact. More detail is included to specifically show GHG emissions, energy consumption and cost and e-waste by computer type. The report can be used as a baseline to understand your organisation’s current impact and/or to comply with CSRD reporting requirements.

What’s included in the ‘Change’ sustainable IT strategy report?

The report takes the results from the baseline report and models sustainable IT strategies. These include extending device lifespans organically or using alternative operating systems, plus introducing carbon footprint as a selection criterion. Similar to the baseline report, this strategy report includes a exec summary page follow by detailed tables showing current carbon footprint, electricity consumption, e-waste, utility and procurement costs and the reductions and savings available by implementing each of the 6 proposed strategies.

What does the ‘Compare’ app do?

Compare enables businesses and organisations to introduce carbon footprint as a selection criterion during purchasing exercises. Users can stack rank computers, monitors and displays by carbon footprint and or energy efficiency to help select low carbon footprint devices. As the selection is based upon where your company operates and how long your usually keep computers, the results are tailored especially for you. This means that you can select with confidence and buy your computers via your usual supply channel.
