The 3.7% figure is widely cited in research from The Shift Project and other sustainability studies analysing the global carbon footprint of digital technology. It estimates that the internet and associated digital infrastructure, including data centres, networks and user devices, account for a similar level of emissions as the aviation industry.
While exact figures evolve as technology and energy grids change, the direction of travel is clear. Digital demand is increasing, and so is its environmental impact.
That is why measuring, reducing and optimising digital carbon is not theoretical. It is a practical opportunity for businesses to improve efficiency, reduce waste and lead with credible action.
