Digital Habit Quiz

The behaviours that put the most load on energy and networks in everyday digital life fall into roughly five areas. This quiz helps you quickly see where you stand in each one so you can pick what to improve first.

• Browser tab management — the more tabs are open, the more your browser refreshes content and uses memory and CPU. The number of tabs is a simple indicator of device load.
• Email habits — unneeded newsletters and promotions keep piling up and syncing on servers. How often you clean your inbox and unsubscribe is tied to real storage and transfer load.
• Video streaming quality — streaming is the largest share of digital traffic. A single quality setting can change the amount of data transferred several times over.
• Smartphone replacement cycle — the carbon emitted when a device is made can exceed what it emits in use. Replacing devices less often is one of the most effective ways to cut digital carbon.
• Cloud clean-up — duplicate files and unused backups keep sitting in data centers. Regular clean-ups affect both storage space and energy use.

This quiz is not a competition or a ranking. It is a tool to find your starting point. A low score simply means there is more room to improve. Read the tip for each question and pick the one change that is easiest for you to make.
